Cylinder 5 Pressure Sensor Circuit Range/Performance

Where it lives

For P03BE, the description names the sensor as the part involved. The description of P03BE puts it on cylinder 5.

Check these first

• A failing cylinder 5 pressure sensor
• Damaged or corroded wiring at the cylinder 5 sensor
• A sensor 5 installed at the wrong depth or torque
• An ECM misreading the cylinder 5 signal
• Carbon or oil fouling on the sensor 5 tip

What to do next

1. Compare cylinder 5 pressure to the other cylinders on a scan tool
2. Inspect the cylinder 5 sensor connector and wiring
3. Check the sensor 5 installation depth and torque
4. Look for oil or carbon on the sensor 5 tip
5. Replace the cylinder 5 pressure sensor if the signal reads off
6. Clear the code and retest
