Code P0335 2021 Honda CR-V Description
The P0335 diagnostic trouble code (DTC) indicates that the engine control module (ECM) has not received a signal from the crankshaft position sensor (CKP). The CKP sensor is a crucial component that monitors the position and rotational speed of the crankshaft, providing essential data for the ECM to control ignition timing and fuel injection. Without this information, the ECM cannot accurately adjust the engine's performance parameters, leading to potential drivability issues and decreased fuel efficiency.
Common Causes of P0335 2021 Honda CR-V
- Faulty crankshaft position sensor
- Damaged or corroded sensor wiring
- Loose or disconnected sensor connector
- Issues with the reluctor ring on the crankshaft
- ECM software malfunction
Symptoms of P0335 2021 Honda CR-V
- Engine misfires
- Rough idling or stalling
- Reduced fuel efficiency
- Difficulty starting the engine
- Check engine light illuminated
How to Fix P0335 2021 Honda CR-V
- Diagnose the issue by using a scan tool to verify the P0335 code and perform a visual inspection of the CKP sensor, wiring, and connectors.
- Test the CKP sensor's resistance and voltage output to determine if it is functioning correctly.
- Replace the faulty CKP sensor if it fails the tests, ensuring proper installation and connection.
- Clear the DTC from the ECM's memory using the scan tool and perform a road test to verify that the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying issues with the reluctor ring or ECM.
Cost to Fix P0335 2021 Honda CR-V
The typical repair costs for replacing a faulty crankshaft position sensor on a 2021 Honda CR-V can range from $150 to $300, including parts and labor.
