Circuit Description
WARNING: This page is about a different car, the 2000 Saturn LW2 and 2000 Saturn LS2. However, it is still accessible from the selected car via links, so may be relevant.
Anytime a throttle body or ECM is replaced, or there is loss of battery power, ECM must relearn the throttle. Throttle is relearned when ignition is turned on (engine off) for one minute. ECM learns the throttle valve travel and records sensor readings at extreme position. This DTC will set if this process did not occur after throttle body or ECM replacement, or after a loss of power.
