Secondary Air Injection System (EMISSION CONTROL - V8) (page 5 of 8)

EMISSION CONTROL - V8

17-2-30 DESCRIPTION AND OPERATION

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:

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.

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.
