Signal Too High - Intermittent Fault
Signal too high. Intermittent fault
Checking wiring and connectors
Check the boost pressure sensor connector. Check for contact resistance and oxidation. Check for loose connections.
Check the signal cable between control module terminal #A23 (#A23) and boost pressure sensor terminal 3. Check for an intermittent open-circuit. Check for an intermittent short-circuit to supply voltage.
Check the ground lead between control module terminal #A60 (#A60) and boost pressure sensor terminal 2. Check for an intermittent open-circuit.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
