Data note: No recalls found in NHTSA database for this make/model/year. No owner complaints are listed in the provided dataset for this specific issue. Data limitations apply: absence of complaints/recalls in the dataset does not guarantee that the issue cannot occur in the real world. Use this guide as a diagnostic framework supported by general automotive knowledge.

CODE MEANING AND SEVERITY

• What P0336 means:
  • P0336 = Crankshaft Position Sensor A Range/Performance (Bank 1 or Engine). It indicates the crankshaft position (CKP) sensor signal is not within expected range or is not performing reliably. The PCM/ECU uses the CKP signal to synchronize ignition timing and fuel injection with engine position.
• Why it matters:
  • If the CKP signal is out of spec, the engine may fail to start, stall unexpectedly, or run poorly with misfires or irregular idle. In severe cases it can leave you stranded.
• Severity for a 2017-2023 Honda CR-V:
  • Moderate to severe. Potential no-start, rough operation, stall, or misfire. Depending on accompanying codes or voltage conditions, the impact can range from intermittent performance to complete engine failure to start.

COMMON CAUSES ON HONDA CR-V

• Faulty CKP sensor:
  • Worn or failing sensor element, internal degradation, or exposure to heat can degrade waveform consistency.
• Damaged or corroded CKP wiring/connectors:
  • Broken or chafed wires, poor or corroded connector pins, oil contamination near the sensor harness, or poor grounding.
• Oil or coolant intrusion:
  • Oil leaks around the sensor or wiring harness can contaminate the sensor or plug, causing erratic signals.
• Electrical supply or ground issues:
  • Weak battery or charging system problems can create voltage dips that affect sensor readings.
• Timing-related issues:
  • On rare occasions, timing belt/chain wear or jumping timing can disrupt the CKP signal (less common for P0336 specifically, but possible if the engine timing is mechanically out of spec).
• ECU/PCM concerns:
  • A failing or water-damaged ECU can misinterpret CKP data, though this is less common than sensor or wiring faults.
• Model-specific nuances:
  • The CR-V (2017-2023) uses a CKP sensor at the crankshaft area. Variants (gasoline 1.5T and hybrid configurations) rely on CKP data for proper ignition/fuel control; wiring harness routing and sensor placement can vary slightly between trim levels and engine options.

SYMPTOMS YOU MIGHT SEE

• Check Engine Light (CEL) or MIL illuminated with P0336 stored.
• Engine cranks but may not start or starts briefly then stalls.
• Engine may run rough, sputter, or misfire.
• Intermittent no-start or stalling while driving.
• Erratic tachometer behavior or inconsistent idle.
• In some cases, paired codes such as P0335 (CKP circuit malfunction) or P0300 (random/mashboard misfire) may appear alongside P0336.
• No obvious external mechanical damage; symptoms are largely electrical/electronic in nature.

DIAGNOSTIC STEPS (structured approach)

Note: Perform these steps with proper safety precautions. If you’re not comfortable with electrical harness work or timing-sensing components, consult a qualified technician.

Step 0 – Prepare and confirm

• Use a good OBD-II scan tool to confirm code P0336 and check freeze-frame data. Note engine RPM, load, temperature, and any other codes.
• Check the battery and charging system voltage. P0336 can appear or be aggravated by low voltage; aim for a healthy battery voltage around 12.6V with engine off and 13.5–14.8V while running (charging).
• If the vehicle has multiple CKP-related codes (P0335–P0339), record them; this helps determine if the symptom is sensor, wiring, or ECU related.

Step 1 – Visual inspection

• Locate the CKP sensor (location varies by engine option; in many CR-Vs it sits near the crank pulley or along the lower front of the engine).
• Inspect the CKP sensor, connector, and wiring harness for:
  • Visible damage, wear, or chafing.
  • Oil leaks or contamination around the sensor or connector.
  • Corrosion at pins or loose connectors; ensure plug snaps firmly.
  • Any signs of heat damage or abrasion from belts, hoses, or the exhaust.
• If accessible, unplug the connector and inspect the pins for bent or pushed-in contacts. Reseat firmly if appropriate.
• Clean any dirt or oil from the connector terminals if you see contamination, and apply a small amount of dielectric grease on the connector (when reconnected) to resist moisture and corrosion.

Step 2 – Test the CKP signal with live data

• Use a diagnostic scan tool capable of live CKP data or an oscilloscope (preferred) to observe the CKP waveform while the engine cranks and/or runs.
• Expected behavior:
  • With the engine cranking, you should see a stable, repeating CKP waveform that correlates with engine speed (RPM). The waveform should be clean; no dropped pulses or erratic gaps.
  • If the CKP signal is missing, sporadic, or severely noisy, suspect the sensor or wiring.
• If you can access multi-signal data, compare CKP RPM signal against actual engine RPM. Large discrepancies or no signal at all indicate a CKP sensor or wiring problem.
• If you can’t access live CKP data, a diagnostic environment that supports the CKP feed is essential to avoid guessing.

Step 3 – Check for auxiliary causes

• Inspect ignition and fuel system in case P0336 is accompanied by other drivability issues (though P0336 itself is CKP signal related).
• Verify all related fuses and grounds (including those feeding the PCM and CKP sensor circuit).
• If the vehicle has a timing belt/chain service history, verify there’s no obvious timing misalignment or mechanical issue. A major mismatch would typically trigger multiple codes and more severe symptoms.

Step 4 – Rule out related circuits

• If CKP wiring and connector check out, temporarily monitor for any other CKP codes (P0335–P0339). A persistent P0336 with clean wiring and a verified CKP signal strongly points to a sensor issue or ECU interpretation problem.
• If you have access to a replacement CKP sensor, you can perform a swap test to see if the symptom resolves (more precisely, a controlled test: replace CKP sensor with a known-good unit and recheck).

Step 5 – Replacement considerations

• If you determine the CKP sensor is faulty or the wiring is damaged beyond repair, replace the sensor.
• After replacement, follow any re-learn or adaptation procedures your scan tool requires (some Hondas require a crankshaft position sensor relearn or PCM adaptation). Check your tool’s capabilities or the service manual for the exact procedure.

Step 6 – Post-repair verification

• Clear the codes and take the vehicle for a test drive. Monitor for reappearance of P0336 and confirm that related symptoms (start, idle, driveability) have improved.
• Recheck live CKP data during the test drive to confirm stable, proper signal across RPM range.
• If P0336 returns despite a new sensor and clean wiring, broader engine management questions (ECU fault, wiring harness harness routing, or a larger electrical issue) may need professional evaluation.

RELATED CODES

These are commonly seen alongside P0336 or in the same CKP family. They help narrow the fault domain (sensor, wiring, or ECU).

• P0335 – Crankshaft Position Sensor A Circuit Malfunction
  • Indicates a fault in the CKP circuit (sensor, wiring, or PCM) but not necessarily range/quality of the signal.
• P0337 – Crankshaft Position Sensor A Circuit Low Input
  • CKP signal is lower than expected (signal level is too weak).
• P0338 – Crankshaft Position Sensor A Circuit High Input
  • CKP signal is higher than expected.
• P0339 – Crankshaft Position Sensor A Circuit Intermittent/No Signal
  • Signal loses intermittently; can be wiring, connector, or sensor fault.

REPAIR OPTIONS AND COSTS (2025 prices)

Prices vary by region, shop rate, and whether you use OEM or aftermarket parts. The ranges below reflect typical U.S. prices in 2025 and include parts and labor estimates.

• Parts: ECU/PCM replacement or reprogramming.
• Labor: 1–3 hours plus potential programming/tool costs.
• Estimated total: $350–$1000+ depending on supplier and programming needs.
• Notes: This is uncommon and typically pursued only after sensor, harness, and wiring checks have ruled out simpler causes.

Option E: DIY cost savings

• If you have the tools and confidence to replace the CKP sensor yourself (and you confirm wiring integrity), you can save on labor. Expect to spend mainly on the sensor and any small parts (dieslectric grease, connectors).

Important caveats

• Labor rates vary widely by region and shop; use these as ballpark estimates.
• If the CKP sensor is replaced but the fault recurs, a deeper electrical issue or ECU problem may exist and require a more thorough diagnostic by a pro.
• For hybrids or some trims, there may be small differences in sensor location or re-learn requirements; consult for the specific engine code (e.g., 1.5L turbo vs hybrid) if you’re doing a DIY repair.

DIY vs PROFESSIONAL

• DIY pros:
  • Cost savings on labor.
  • Good learning experience if you’re comfortable with basic automotive electrical work.
  • CKP sensor replacement is often straightforward on many Honda engines; however, access varies by model year and trim.
• DIY cons:
  • Some CR-Vs place the CKP sensor in a location that is difficult to access without disassembly; risk of dropping bolts or damaging nearby components.
  • You may need a crankshaft-position relearn or ECU adaptation after replacement, which typically requires a capable scan tool.
  • If oil leaks or wiring harness issues are present, you’ll need to address them properly to prevent future failures.
• Professional route:
  • Faster resolution when a misdiagnosis is suspected, especially if multiple CKP-related codes appear.
  • Access to OEM service information, factory re-learn procedures, and advanced diagnostic tools (scope, advanced data, overlapping diagnoses).
  • Possible warranty coverage if a defect is suspected in the CKP sensor or harness.

DIY step-by-step quick reference (CKP sensor replacement)

• Tools you may need: jack stands, wheel chocks, basic hand tools, Torx or hex drivers as required, multimeter, dielectric grease, replacement CKP sensor, possibly a scan tool with crank relearn capability.
• Steps:
  • Disconnect the negative battery terminal and wait a few minutes.
  • Locate the CKP sensor; unplug the electrical connector and release any locking tab.
  • Remove the sensor mounting bolts; carefully extract the old sensor.
  • Compare the old and new sensors; install the new sensor with the correct orientation and torque to spec.
  • Reconnect the harness; apply dielectric grease to the connector if desired and reseat.
  • Reconnect the battery; start the engine and watch for a test drive; clear codes if you have a relearn tool.
  • If required, perform crankshaft position relearn using a compatible scan tool.
  • After replacement, monitor for recurrences of P0336.

PREVENTION

• Regular maintenance helps reduce the likelihood of CKP-related problems:
  • Keep engine oil leaks under control; clean up any oil around the front of the engine and wiring harness.
  • Use quality oil and ensure the engine is not starved for oil pressure, as poor lubrication can affect sensor performance indirectly through heat and contaminants.
  • Inspect the CKP sensor and wiring during routine service (especially on higher-mileage CR-Vs) for signs of wear, oil exposure, or corrosion.
  • Protect wiring harnesses from heat exposure, sharp edges, and moving components. Use protective sleeves or routing adjustments if necessary.
  • Address electrical system health (battery voltage and charging system) to avoid voltage dips that can affect sensors.
  • If replacing the CKP sensor, opt for a reputable part (OEM or well-known aftermarket) and ensure proper torque and seating; perform relearn/adaptation if required by your tool.

Important data caveat

• The provided NHTSA data indicates no recalls and no owner complaints for this issue (P0336) on the 2017-2023 Honda CR-V within the given dataset. This does not rule out real-world occurrences; it only reflects the specific dataset. Always base decisions on your vehicle’s actual symptoms, diagnostic findings, and service information for your particular engine variant (gasoline 1.5T or hybrid).

Summary

• P0336 on a Honda CR-V usually points to a CKP sensor signal range/quality issue. Common root causes are a faulty CKP sensor, damaged wiring or connectors, or oil/contamination at the sensor. Diagnostic steps emphasize confirming the code, visually inspecting the sensor and harness, testing the CKP signal with live data, and performing a sensor swap if the signal is out of spec. Related codes (P0335–P0339) can help confirm whether the issue is sensor, wiring, or ECU-based. Repair costs vary but replacing the CKP sensor is the most common fix, with typical total costs in the low to mid-hundreds depending on parts choices and labor. DIY replacement is feasible for many hands, but some CR-V configurations may require professional tools or programming. Finally, preventive care includes keeping the CKP area clean and dry, ensuring proper electrical health, and routing/wrapping to protect the sensor and wiring from heat and oil exposure.
