Cylinder 10 Pressure Sensor Circuit Intermittent/Erratic

Where it lives

For P2356, the circuit described runs through the sensor. The description of P2356 puts it on cylinder 10.

Check these first

• An intermittent open or short in the cylinder 10 pressure sensor circuit
• Corrosion or water in the cylinder 10 sensor connector
• A failing cylinder 10 pressure sensor element
• Loose mounting letting the cylinder 10 sensor vibrate

What to do next

1. Read cylinder 10 pressure sensor data on a scan tool while wiggling the harness
2. Inspect the cylinder 10 sensor connector for corrosion or water
3. Test the cylinder 10 sensor circuit for an intermittent fault
4. Check the cylinder 10 sensor mounting
5. Replace the cylinder 10 pressure sensor if the circuit tests good
6. Clear the code and retest
