EMISSION CONTROL - V8
Checking Malfunctions
In the event of faults in the Secondary Air Injection system such as noticeable noise, scorching on the lines or fault
indication P Codes, all components and the system must be tested for proper functioning on completion of repairs.
Long term malfunctions with some components can result in damage to other system components. This can result in
excessive instances of No Fault Found (NFF) components in warranty returns and multiple repeat complaints from
the customer before the fault is rectified.
For example; a malfunction of the vacuum solenoid could result in uncontrolled opening of the SAI control valves. The
could eventually lead to damage to the SAI valves and also the SAI pump. In this case, if only the pump was replaced,
repeated failure may eventually occur over a period of time.
