P0366 2020 Honda CR-V Code - Camshaft Position Sensor 'B' and Crankshaft Position Sensor Incorrect Phase Detected

P0366 indicates that the Engine Control Module (ECM) has detected an incorrect phase relationship between the camshaft position sensor 'B' (exhaust side) and the crankshaft position sensor.

Symptoms may include the check engine light illuminating, rough idling, reduced engine performance, poor acceleration, stalling, or difficulty starting the engine.

Potential causes include a faulty camshaft position sensor, damaged wiring or connectors, a malfunctioning crankshaft position sensor, timing issues, or engine control module (ECM) problems.

Yes, a stretched or misaligned timing chain can cause the camshaft and crankshaft sensors to detect an incorrect phase relationship, triggering the P0366 code.

Diagnosing involves scanning the ECM for additional codes, visually inspecting the sensors and wiring, testing the camshaft and crankshaft position sensors, and verifying proper engine timing.

Repairs may include replacing a faulty camshaft position sensor, repairing damaged wiring or connectors, correcting timing chain issues, or updating/replacing the ECM if necessary.

Driving with the P0366 code is not recommended, as it can cause engine stalling, poor performance, and potentially lead to further damage.

Repair costs vary depending on the cause but typically range from $100 to $300 for sensor replacement, or higher if timing chain repairs are needed.

While unlikely, a weak battery or charging system issues can cause voltage fluctuations that may affect sensor readings and trigger this code.

In most cases, reprogramming is not needed, but the ECM should be reset, and the system rescanned to ensure the issue is resolved.
