Camshaft Position Sensor Circuit High (Bank 1)
The P0368 code indicates that the Engine Control Module (ECM) has detected a voltage signal from the camshaft position sensor on Bank 1 that is higher than the expected range. This sensor monitors the position of the camshaft relative to the crankshaft to optimize fuel injection and ignition timing. A high circuit condition typically points to a short to voltage, a faulty sensor, or wiring issues. This can cause drivability problems and may prevent the vehicle from starting.
01. Most Common Causes
- Faulty camshaft position sensor
- Short to voltage in the sensor circuit
- Damaged wiring or connector
- Corroded terminals
- ECM failure (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine hard to start or no start
- Rough idle or stalling
- Poor acceleration or hesitation
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the camshaft position sensor connector and wiring for damage, corrosion, or shorts.
Step 3: Test the sensor's voltage supply and ground circuits with a multimeter.
Step 4: Check the sensor signal voltage at the ECM connector; compare to specifications.
Step 5: If all circuits are good, replace the camshaft position sensor.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with P0368 as it can cause stalling or no-start conditions, leading to unsafe driving situations.
How much does it cost to fix?▼
The typical repair cost ranges from $50 to $150 for a DIY sensor replacement, or $100 to $250 if professionally diagnosed and repaired.
