Checking components and wiring

Check the signal cable between control module terminal #A23 (#A23) and boost pressure sensor terminal 1. Check for an open-circuit. Check for a short-circuit to supply voltage.

HINT: With the ignition on and the boost pressure sensor connector disconnected, the voltage between terminal 1 and ground terminal must be approximately 5 V. 

Check the ground lead between control module terminal #A60 (#A60) and boost pressure sensor terminal 2. Check for an open-circuit.

Remedy as necessary.
