P0750 Code: Honda CR-V (2017-2023) - Causes, Symptoms & Fixes

Here is a comprehensive diagnostic guide for OBD-II code P0750 as it applies to 2017–2023 Honda CR-V. The guide sticks to the data you provided, and then adds practical diagnostic and repair guidance based on general automotive knowledge.

CODE MEANING AND SEVERITY

• Code meaning: P0750 typically indicates a shift solenoid A malfunction or its control circuit is out of range. In Honda CVTs, this solenoid helps regulate hydraulic pressure to adjust the pulleys and belt ratio. A fault can prevent proper transmission shifting or cause reluctance to shift into or out of certain ranges.
• Severity (high level): Moderate to high. If left unaddressed, it can lead to slipping, erratic shifts, reduced drivability, or the transmission entering a limp/limited-performance mode. In some cases the vehicle may run with the MIL illuminated but still drive; in others you may experience hard shifts or failure to upshift. Replacing or repairing the solenoid/valve body or related wiring is usually required to restore proper operation.
• Data note: No recalls found in NHTSA database for this issue on 2017–2023 CR-V, and owner complaint data for this exact issue/model/year is not listed in the provided dataset.

COMMON CAUSES ON HONDA CR-V (2017–2023, CVT)

• Faulty shift solenoid A (S/A) or its internal valve body passage
• Electrical problems: damaged, corroded, loose, or unplugged wiring harness or connector to the transmission solenoid or TCM/ECU
• Transmission fluid issues: low level, degraded, contaminated, or incorrect fluid for Honda CVT (Honda CVT Fluid Type 2 in many markets)
• Control module/wiring issues: TCM (transmission control module) communication error or software/calibration needs an update
• Mechanical valve body wear or internal sticking of solenoids
• Sensor or command misreads: related sensors causing the TCM to command the wrong solenoid operation
• Intermittent faults: intermittent electrical ground or harness chafing

SYMPTOMS (typical in 2017–2023 CR-V with P0750)

• Transmission may not shift smoothly or may hesitate to upshift/downshift
• Harsh or delayed shifts, especially when moving from drive to higher gears or during acceleration
• Transmission entering “limp home” or reduced-power mode; speed may be limited
• Check Engine Light (CEL) or Transmission Malfunction Indicator Light (MIL) on
• Small or no movement occurs when commanded in certain gears (e.g., stuck in a lower or higher gear)
• DTC P0750 may appear alongside related codes such as P0751, P0752, P276B, P077? depending on the CVT/gear selection logic and fault history

DIAGNOSTIC STEPS (structured approach)

Note: Use a capable OBD-II scan tool with live data, freeze frame data, and the ability to read manufacturer-specific transmission data. If you’re not comfortable with transmission work, seek a qualified technician.

• Step 1: Confirm and scope the fault

  • Read DTC P0750 plus any related codes (P07xx family, or P2700/others tied to CVT controls) to understand the fault history.
  • Note freeze-frame data (vehicle speed, RPM, gear selected at the time of fault, engine load, coolant temp, etc.).

• Step 2: Visual inspection and basic checks

  • Inspect transmission fluid level and condition. For CVTs, level is checked with the engine idling and the vehicle on level ground; fluid should be amber to reddish, with a slightly sweet scent if clean. If fluid is dark, burnt, or has a metallic smell, it may indicate contamination or wear.
  • Check for obvious wiring/connectors at the transmission end of the solenoid pack. Look for loose connectors, broken/shorted wires, corrosion, or damaged harnesses.
  • Inspect the battery and charging system. Poor electrical supply can trigger transmission electronics faults.

• Step 3: Fluid and condition related tests

  • If the fluid is old or contaminated, perform a CVT fluid service per Honda guidelines (note: some CVT designs require a specific Honda CVT fluid and procedures; using the wrong fluid can cause performance issues or damage).
  • If the vehicle has not had a CVT fluid change within the recommended interval, plan for a replacement or flush if advised by a Honda service procedure.

• Step 4: Electrical tests (solenoid harness and control circuit)

  • With the ignition OFF, inspect for damaged grounds near the transmission; verify battery negative terminal and chassis grounds are clean and tight.
  • Check resistance of the shift solenoid A (S/A) and any related solenoids per Honda service data for the CVT (values vary by model year; you’ll need the official spec from Honda’s service data). Compare readings to schematic tolerances.
  • Inspect continuity and resistance of the wiring between the TCM/ECU and the solenoid. Look for high resistance, open circuits, or shorts.
  • If possible, perform a live data test to watch solenoid activation (duty cycle, voltage supply) when commanded by the TCM. Abnormal signals often indicate a faulty solenoid or a wiring issue.

• Step 5: Software and control module checks

  • Confirm there are no pending software updates for the TCM/ECU that affect transmission control. In some cases, a software update fixes shift logic or calibration that could trigger P0750.
  • If a TCM fault is suspected, perform a specific diagnostic test for the TCM circuits and consider a reflash or replacement if indicated.

• Step 6: Mechanical assessment

  • If electrical tests pass and fluid is good, consider valve body condition and internal cleanliness. Debris or varnish can cause sticking or improper valve operation.
  • In cases where a valve body or solenoid is suspected but not easily accessible, a professional flush/clean or replacement of the valve body might be necessary.

• Step 7: Road test and re-check

  • After any service, clear codes and road test the vehicle through typical driving cycles (cold and warm starts, acceleration, cruising, and deceleration) to verify if P0750 returns.
  • Re-scan if symptoms persist to see if newly stored codes appear.

RELATED CODES

• P0751, P0752, P0753, etc. (variants indicating shift solenoid A/B issues or related control circuit faults)
• P2710, P2714, P279D and other CVT-related control codes (valve body, pressure control, or TCM communication codes)
• P0868 (transmission fluid pressure sensor or related CVT pressure concerns)
• P0850, P0852, etc. (torque converter or shift solenoid circuitry in some systems)
  Note: In the Honda CR-V CVT, many P07XX codes revolve around shift solenoids and their control circuits. Always review the full DTC set and freeze-frame data to identify the most relevant driver fault.

  • Dealers typically charge higher labor rates but may have more direct access to Honda service data and updated software.
  • Independent shops can be cost-effective but ensure they have CVT-specific experience and proper diagnostic equipment for Honda CVT systems.

DIY vs PROFESSIONAL

• DIY considerations:

  • If you have a solid understanding of transmission electronics, wiring, and CVT operation, you can perform initial diagnostics (visual checks, fluid condition, basic solenoid resistance checks) and possibly replace a solenoid or clean/flush the valve body with proper guidance.
  • Risks: CVT failures due to improper fluid type, improper valve body work, or improper torque on transmission components. CVTs are sensitive to contamination; incorrect fluid can cause further damage.

• When to seek a professional:

  • If you observe persistent DTCs with P0750 plus related codes, intermittent symptoms, or you don’t have diagnostic access to CVT-specific data (solenoid resistance specs, pin-out diagrams, live data for solenoid duty cycles).
  • If the car exhibits limp mode or you lack a safe environment to perform transmission work.
  • If the valve body or solenoids need removal from the CVT, which typically requires special tools, transmission jigs, and knowledge.

• What a professional will likely do:

  • Confirm DTCs with a Honda-compatible scanner
  • Test solenoids, wiring, and TCM communications
  • Inspect or replace shift solenoids and/or valve body
  • Inspect and service CVT fluid as per Honda specification
  • Recalibrate or update TCM software if required
  • Perform road testing and re-scan

PREVENTION

• Regular CVT maintenance:
  • Use the correct Honda CVT fluid as specified for your CR-V year/model.
  • Change CVT fluid at the intervals recommended by Honda for your model; do not mix fluids.
  • If you notice fluid level or condition changes, check promptly.
• Avoid contamination:
  • Only service CVT using clean tools and avoid introducing contaminants into the transmission.
  • If you service it yourself, ensure caps, funnels, and containers are clean and unused.
• Gentle driving habits:
  • Avoid aggressive acceleration and heavy loads at low speeds, which can increase hydraulic pressure demands and wear on solenoids.
  • When towing (if applicable to your model), follow Honda’s guidelines for towing limits to reduce strain on CVT components.
• Electrical health:
  • Maintain good battery health and clean grounds; electrical faults can manifest as transmission control issues.
• Software updates:
  • Periodically check for TCM/ECU software updates from Honda; updates can improve shift control and fault handling.
