Checking components and wiring

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

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 ground.

Remedy as necessary.
