Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit Description
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.
