What does Error Code P0365 mean?
Moderate Issue
DTC Code P0365 indicates an issue with the Camshaft Position Sensor 'B' Circuit Bank 1. This code is triggered when the Engine Control Module (ECM) fails to detect a signal from the camshaft position sensor during initial engine cranking, affecting ignition and fuel injection timing.
What are the symptoms of Error Code P0365?
- Engine Light ON: The Check Engine Light or Service Engine Soon Warning Light illuminates, indicating a potential issue with the camshaft position sensor 'B' circuit on bank 1.
- Lack/Loss of Power: The vehicle may experience a noticeable reduction in power output, which can be linked to incorrect camshaft timing due to sensor malfunction.
- Engine Stall: The engine may stall unexpectedly, which can be attributed to the camshaft position sensor failing to provide accurate data for engine timing.
What causes Error Code P0365?
- The camshaft position sensor may be malfunctioning, leading to incorrect readings and triggering the error code.
- An open or shorted harness in the camshaft position sensor can disrupt the signal, causing the error.
- Poor electrical connections in the camshaft position sensor circuit can result in intermittent or no signal.
- A faulty starter motor can affect the engine's ability to start, indirectly causing the error code.
- Issues in the starting system circuit can lead to improper engine cranking, affecting sensor readings.
- A dead or weak battery can cause insufficient power supply, impacting the sensor's performance.

How to fix Error Code P0365?
- Verify DTC Code: Confirm the presence of DTC P0365 using an OBD-II scanner. Check for any additional codes that may be related, such as P0010 through P0025 or P0335 through P0349.
- Inspect Camshaft Position Sensor: Locate the Camshaft Position Sensor 'B' on Bank 1. Inspect the sensor and its connector for any signs of damage, corrosion, or loose connections.
- Check Wiring and Connectors: Examine the wiring harness and connectors leading to the Camshaft Position Sensor for any signs of wear, fraying, or disconnection. Ensure all connections are secure.
- Test Sensor Voltage: Using a multimeter, test the voltage supply to the Camshaft Position Sensor. Compare the readings to the manufacturer's specifications to ensure proper voltage is being supplied.
- Perform Sensor Resistance Test: Measure the resistance of the Camshaft Position Sensor. Compare the resistance values to the manufacturer's specifications to determine if the sensor is functioning correctly.
- Check Timing Components: Inspect the timing chain or belt and related components for wear or misalignment, which could affect the camshaft position.
- Replace Faulty Components: If any components are found to be faulty, replace them. Clear the DTC code and perform a test drive to ensure the issue is resolved.
