Signal Too Low. 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 fuel 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 ground.
- Check cable between tank pressure sensor terminal 3 and engine control module (ECM) #B15 via connector 24/4 terminal E4 and connector 24/2 terminal C5 for an intermittent short-circuit to ground and an intermittent open-circuit.
- Check cable between accelerometer terminal 1 and engine control module (ECM) #B1 for an intermittent short-circuit to ground.
- Check cable between air conditioning (A/C) pressure sensor terminal 3 and engine control module (ECM) #B29 for an intermittent short-circuit to ground.
