Checking components and wiring

Check the boost pressure sensor connector. Check for contact resistance and oxidation.
Check the signal cable between engine control module (ECM) terminal #A23 (#A23) and boost 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 boost pressure sensor terminal #1. Check for an open-circuit.

Remedy as necessary.
