Checking The Component 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 between terminals #1 and #2 (sensor side). Check the resistance.

  Check the signal cable between engine control module (ECM) terminal #A66 (#B6) and fuel pressure sensor terminal #2. Check for a short-circuit to supply voltage. Check for an open-circuit.

  Check the ground lead between engine control module (ECM) terminal #A15 (#A15) and fuel pressure sensor terminal #1. Check for an open-circuit.

  Remedy as necessary.
