Signal Too High. Intermittent Fault

SIGNAL TOO HIGH. INTERMITTENT FAULT





Checking Cables and Terminals

- Check fuel tank pressure sensor and control module connectors and connectors 24/2 and 24/4 for loose connections, contact resistance and oxidation.
- Check cable between tank pressure sensor terminal 3 and engine control module (ECM) #B31 via connector 24/4 terminal E5 and connector 24/2 terminal C6 for an intermittent short-circuit to supply voltage and an intermittent open-circuit.
- Check cable between tank pressure sensor terminal 2 and engine control module (ECM) #B28 via connector 24/4 terminal E6 and connector 24/2 terminal C7 for an intermittent open-circuit.

- Then proceed to test step below.

Fault-Tracing Information

- For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.
- Do you want to repeat fault-tracing?

Yes:
- Return to Checking Cables and Terminals section above.

No:
- Operation done.
