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 2 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 1 and engine control module (ECM) #B28 via connector 24/4 terminal E6 and connector 24/2 terminal C7 for an intermittent open-circuit.
Then continue with:
