Where it lives

For P2348, the sensor sits on the circuit this code reports. The description of P2348 puts it on cylinder 9.

Check these first

• An open or short in the cylinder 9 pressure sensor circuit
• A failed cylinder 9 pressure sensor
• A backed out pin at the cylinder 9 sensor connector
• Chafed wiring along the cylinder 9 sensor harness

What to do next

1. Read cylinder 9 pressure sensor voltage on a scan tool
2. Test the cylinder 9 sensor circuit for open and short faults
3. Check the cylinder 9 sensor connector pins
4. Verify reference and ground at the cylinder 9 sensor
5. Replace the cylinder 9 pressure sensor if the circuit tests good
