Checking Components And Wiring
Check the fuel pressure sensor connectors. Check for contact resistance and oxidation.
Check the signal cable between engine control module (ECM) terminal #A2 (#A2) and fuel pressure sensor terminal #4. 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.
Try a new fuel pressure sensor if no fault is found during the above fault-tracing.
