P0335 Code: Toyota Camry (2018-2024) - Causes, Symptoms & Fixes

Note on the data you provided

• No recalls found in NHTSA database for 2018-2024 Toyota Camry in the information above.
• Owner complaint in the data set involves P0442 (evaporative system small leak) with no mention of P0335.
• This guide uses general, model-relevant knowledge for Toyota Camry along with the code meaning and common failure modes. The data provided does not list P0335-specific complaints or recalls, so the guide focuses on typical CKP (Crankshaft Position Sensor) A Circuit issues as they relate to Camry models in this age range.

CODE MEANING AND SEVERITY

• What P0335 means:
  • P0335 = Crankshaft Position Sensor A Circuit
  • The Crankshaft Position Sensor (CKP) provides the PCM with the engine crankshaft’s position and rotational speed. The PCM uses this information to control ignition timing and fuel injection.
  • A failure code indicates the PCM is not receiving a valid CKP signal or the signal is out of expected range. This can result from a faulty sensor, wiring problems, or PCM issues.
• Severity and potential impact:
  • High severity. In many Camry engines (4-cylinder and V6), a P0335 can cause no-start, stalling, misfires, reduced power, or irregular idle. In some cases the vehicle may run poorly or enter a limp mode to protect the engine.
  • Because ignition timing and fuel delivery rely on CKP data, a confirmed P0335 should be addressed promptly to avoid abrupt stalling or engine damage.

COMMON CAUSES ON TOYOTA CAMRY

• Faulty CKP sensor itself (most common)
• Damaged or fractured CKP sensor wiring harness or connectors (insulation wear, corrosion, loose connectors)
• Wiring shorts to power, ground, or signal line
• Damaged reluctor ring or intermittent clearance (the reluctor/ toothed ring near the crankshaft that the CKP sensor reads)
• Timing chain/belt alignment or tension issues affecting the CKP signal
• PCM/ECU fault or software/calibration discrepancy
• Oil or contamination affecting sensor or connector (especially if sensor sits close to oil pathways)
• Aftermarket modifications or wiring interference

SYMPTOMS TO EXPECT (P0335 in a 2018-2024 Camry)

• Engine cranks but does not start, or starts intermittently and stalls
• Engine starts but stalls soon after or runs very poorly
• Check Engine Light is on (DTC P0335)
• Rough idle or misfires
• Decreased power, poor acceleration, or hesitation
• Possible intermittent no-spark/no-fuel events
• In some cases, other related CKP/PCM-related codes may appear as secondary DTCs

DIAGNOSTIC STEPS (systematic approach)

Important notes:

• Start with a scan tool that can view live data and freeze-frame data.
• Safety: follow standard vehicle-service precautions; disconnecting battery may set additional codes; if the engine runs, ensure it is in a safe operating environment before performing any tests.

Step-by-step:

Confirm DTC and capture freeze-frame data

• Use a professional scan tool to confirm P0335 is current (not history) and note engine RPM, load, and other related data in the freeze-frame.

Visual inspection

• Inspect CKP sensor and its connector for signs of damage, corrosion, oil contamination, or loose connections.
• Inspect the wiring harness for wear, chafing, cracked insulation, or bent/pinched wires, especially where routing passes near moving parts or the exhaust.

Check CKP sensor location and condition

• Identify CKP sensor location on your Camry engine (both 4-cylinder and V6 models have CKP near the timing cover area). Look for any signs of oil seepage or mounting issues.
• If accessible, gently wiggle the sensor in its harness to test for intermittent connection. Do not apply excessive force.

Test the sensor signal with a scan tool or oscilloscope (live data)

• With the engine cranking (or running if possible), observe the CKP sensor signal waveform or digital data:
  • The CKP should produce a clean, regular signal corresponding to rotating teeth or reluctor marks.
  • If the signal is absent, erratic, or missing intermittently, suspect sensor, wiring, or reluctor ring issues.
• If your tool can display a voltage or digital pattern, compare it to the manufacturer’s spec for Camry CKP sensors (if available in service data).

Verify power, ground, and signal circuits with a multimeter

• Power (reference voltage) to the CKP sensor: verify within spec (often 5V reference on many vehicles, but confirm with service data for Camry).
• Ground: verify a solid ground path from sensor to engine block/PCM ground.
• Signal circuit (data line): check for continuity and inspect for short to ground or short to voltage.

Inspect the reluctor ring and mechanical timing relation

• If accessible, inspect the crankshaft reluctor ring for damage, misalignment, or missing teeth.
• If timing chain components (tensioner, guides) are known to cause timing irregularities, these should be evaluated by a professional. In Camry engines with timing chains, a stretched chain or worn tensioner can affect CKP reliability.

Check for related codes and data

• Look for P0330, P0336, P0337, P0338, P0339 (other CKP-related codes) or P0340/P0341 (Camshaft Position Sensor) which can indicate broader timing/sensor issues.
• If multiple CKP-related codes appear, the problem may be electrical or PCM-related, or there may be a more systemic timing issue.

Perform a manual test (where trained)

• If you have the knowledge and tools, you can perform a known-good-signal substitute test (some technicians temporarily apply a simulated signal) to see if the engine will start, helping isolate sensor vs PCM vs wiring issues. This is advanced and not recommended for casual DIYers.

Decide on repair path based on findings

• If the CKP sensor shows physical damage, poor signal, or wiring faults, plan replacement and wiring repair as needed.
• If the reluctor ring or timing components are damaged, plan those repairs, which are more involved and costly.
• If the PCM appears at fault (rare), professional diagnosis is required.

After repair — verification

• Clear codes and perform road test or simulated driving to ensure the CKP signal remains valid.
• Re-scan for DTCs to confirm P0335 does not return.

Tips for test interpretation

• A true mechanical timing problem may produce a P0335 along with other CKP-related codes; however, a random intermittent CKP signal loss with no mechanical fault can also trigger P0335.
• A vehicle that starts, runs briefly, then stalls, often suggests an intermittent CKP signal or a wiring issue rather than a completely failed sensor.

DIY vs PROFESSIONAL

• DIY feasibility:
  • Moderate difficulty for a capable home mechanic with basic tools.
  • CKP sensor replacement is generally straightforward where the sensor is accessible without removing major components.
  • Common risks: misdiagnosing wiring issues, damaging connectors, or inadvertently causing oil leaks or short circuits.
• Professional route:
  • Recommended if:
    • Access to the CKP sensor is limited or you suspect timing-chain related issues.
    • You do not have appropriate diagnostic tools (live data, oscilloscope) to verify CKP signal quality.
    • The vehicle is stalling at speed or fails to start in hazardous conditions.
  • A dealer or experienced shop can also handle PCM-related issues or timing-chain work with proper torque specs and programming.

PREVENTION

• Regular inspections of electrical connectors and wiring near the engine (protect wiring from heat, oil, and abrasion).
• Address oil leaks promptly; oil on sensor connectors can cause intermittent signals.
• Use high-quality replacement parts (OEM or reputable aftermarket) to reduce early failure risk.
• Maintain the battery and charging system; a weak battery or poor grounding can complicate sensor operation and diagnostic results.
• If performing heavy maintenance that involves engine timing components, follow Toyota service procedures for timing and sensor calibration to avoid WP (wrong perspective) CKP issues.
• Periodically re-check with a scan tool after any work on the ignition/fuel/instrument cluster to ensure no new DTCs appear.

Important caveats and data limits

• The provided NHTSA data set does not include a P0335 complaint or recall for 2018-2024 Toyota Camry. Therefore, the diagnostic guide focuses on general, model-relevant CKP sensor failures typical for Camry vehicles in this generation, not on a documented official defect that appeared in the supplied data.
• Costs are estimates for 2025 and can vary by region, shop, and whether the work is done at a dealership or independent shop.
• While P0335 is commonly a CKP sensor or circuit problem, a proper diagnosis should rule out wiring issues and, if necessary, timing-related concerns before replacing the sensor.

If you want, I can tailor the diagnostic steps to your exact Camry variant (engine code, year, trim) and provide more precise labor times and part numbers for that specific model.
