Cylinder 12 Pressure Sensor Circuit Low

Where it lives

For P2368, the sensor sits on the circuit this code reports. The description of P2368 puts it on cylinder 12.

Check these first

• A short to ground on the cylinder 12 pressure sensor signal wire
• An open in the cylinder 12 sensor ground circuit
• A failed cylinder 12 pressure sensor
• A low reference voltage at the cylinder 12 sensor

What to do next

1. Read cylinder 12 pressure sensor voltage on a scan tool
2. Test the cylinder 12 sensor signal wire for a short to ground
3. Check the cylinder 12 sensor ground and reference circuits
4. Replace the cylinder 12 pressure sensor if the circuit tests good
5. Clear the code and retest
