Cylinder 11 Pressure Sensor Circuit

Where it lives

For P235C, the sensor sits on the circuit this code reports. The description of P235C puts it on cylinder 11.

Check these first

• An open or short in the cylinder 11 pressure sensor circuit
• A failed cylinder 11 pressure sensor
• A backed out pin at the cylinder 11 sensor connector
• Rub through on the cylinder 11 sensor harness

What to do next

1. Read cylinder 11 pressure sensor voltage on a scan tool
2. Test the cylinder 11 sensor circuit for open and short faults
3. Check the cylinder 11 sensor connector pins
4. Verify reference and ground at the cylinder 11 sensor
5. Replace the cylinder 11 pressure sensor if the circuit tests good
6. Clear the code and retest
