EMISSION CONTROL - V8
If the SAI vacuum solenoid valve malfunctions, the following fault codes may be stored in the ECM diagnostic
memory, which can be retrieved using TestBook/T4:
P-code
P0412
Description
SAI vacuum solenoid valve powerstage fault - harness damage, short circuit to
battery supply voltage
P0413
P0414
SAI vacuum solenoid valve not connected, open circuit
SAI vacuum solenoid valve short circuit to ground
NOTE: Refer to 'SAI System Fault Finding' and 'Checking Malfunctions on SAI System' at the end of this section to
determine root cause of fault codes.
As a result of the SAI vacuum solenoid malfunction, other fault codes may also be stored in the ECM diagnostic
memory. These may include the following:
NOTE: A malfunction of the valve is logically expected to result in both engine banks reporting the same fault.
