Diagnostic Aids

WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Do not operate AIR pump for more than 60 seconds. Continuous operation of AIR pump in excess of 60 seconds will damage the AIR pump.

If the DTC cannot be duplicated and is determined to be intermittent, reviewing the Failure Records can be useful in determining when the DTC was last set. Also refer to INTERMITTENT CONDITIONS  under SELF-DIAGNOSTIC SYSTEM.
