Checking components and wiring

HINT: The fuel temperature sensor is integrated in the fuel pressure sensor. 

Check the fuel pressure sensor connectors. Check for contact resistance and oxidation.

Check the fuel pressure sensor resistance. Take readings between terminals #1 and #2.

Check the signal cable between control module terminal #A3 (#A3) and fuel pressure sensor terminal #2. Check for a short-circuit to supply voltage. Check for an open-circuit.

Check the ground lead between control module terminal #A60 (#A60) and fuel pressure sensor terminal #1. Check for an open-circuit.

Remedy as necessary.
