Checking cables
Check fuel tank pressure sensor connector for contact resistance and oxidation according to Contact resistance and oxidation and loose connections according to Loose connections (terminals) . Check particularly for any damage.
Check ground lead between control module #B4 (#B14) and fuel tank pressure sensor connector #1 for an intermittent open-circuit according to Open-circuit, intermittent faults .
Check signal cable between control module #B31 (#B41) and fuel tank pressure sensor connector #2 for an intermittent open-circuit according to Open-circuit, intermittent faults .
Check power supply cable between control module #B10 (#B20) and fuel tank pressure sensor connector #3 for an intermittent open-circuit according to Open-circuit, intermittent faults .
Check signal cable between control module #B31 (#B41) and fuel tank pressure sensor connector #2 for an intermittent short-circuit to supply voltage according to Short-circuit to supply voltage, intermittent faults .
HINT: Use a test screwdriver with at least a 3 W bulb to determine if the cable is short-circuited to supply voltage.
