Signal Sporadic. Intermittent Fault

Checking cables and terminals
- Check fuel tank pressure sensor and control module connectors for loose connections, contact resistance and oxidation.
- Check cable between fuel tank pressure sensor terminal 3 and control module #B15 for an intermittent open-circuit, an intermittent short-circuit to ground and an intermittent short-circuit to supply voltage.
- Check cable between fuel tank pressure sensor terminal 2 and control module #B31 for an intermittent open-circuit, an intermittent short-circuit to ground and an intermittent short-circuit to supply voltage.
- Check cable between fuel tank pressure sensor terminal 1 and control module #B28 for an intermittent open-circuit.
- The fuel tank pressure sensor power cable is connected inside the engine control module (ECM) to the air conditioning (A/C) pressure sensor, atmospheric pressure sensor and accelerometer power cables. If anything happens to any of these cables all four will be affected.

Check cables between:
- air conditioning (A/C) pressure sensor terminal 3 and engine control module (ECM) #B29.
- atmospheric pressure sensor terminal 1 and engine control module (ECM) #B15.
- accelerometer terminal 1 and engine control module (ECM) #B1 for an intermittent short-circuit to supply voltage and an intermittent short-circuit to ground.
