Camshaft Position Sensor Circuit Malfunction (Bank 1)
The P0365 code indicates a problem with the camshaft position sensor circuit on bank 1 (typically the side of the engine with cylinder #1). The sensor monitors the position of the camshaft relative to the crankshaft, which is critical for proper ignition timing and fuel injection. When the PCM detects an abnormal voltage or signal from the sensor, it sets this code. Common causes include a faulty sensor, wiring issues, or a damaged reluctor ring.
01. Most Common Causes
- Faulty camshaft position sensor
- Wiring or connector issues (open, short, corrosion)
- Damaged reluctor ring or timing chain issues
02. Symptoms You Will Notice
- Check Engine Light on
- Engine misfire or rough idle
- Hard starting or no start
- Reduced engine power and poor fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the sensor and wiring for damage or corrosion.
Step 3: Test sensor resistance and voltage with a multimeter.
Step 4: Check for proper sensor gap and reluctor ring condition.
Step 5: Replace sensor if faulty; clear codes and test drive.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the engine may stall or run poorly, potentially causing further damage.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on the vehicle and shop rates.
