PURPOSE
Some dealers have reported customer stated concerns of a lack of throttle response at initial start-up
with CEL (Check Engine light) illumination when ambient temperatures are extremely cold. These
vehicles have been repaired in various ways including replacement of the throttle body assembly or
the TAC (Throttle Actuator Control) relay and finally, just allowing the vehicle to sit in the shop/garage
for a period of time. MMNA is suggesting that dealers replace the TAC relay (8627A049) in order to
address this concern. Replacing any other components is unnecessary. Please follow the guidelines
below when addressing this type of concern.
1) Customer states vehicle lacks throttle response upon initial start-up and has the CEL
illuminated.
2) Dealer confirms the presence of CEL illumination and retrieves DTC(s).
3) DTC(s) active/stored in ECM is P0657 (other DTCs may be present at the time of inspection)
4) Replace TAC relay with part number 8627A049
5) Perform “Read and Erase” function in the Scan Tool and return the vehicle to the customer.
