RE:
Stored DTCs (including P0657) in Extremely Cold Ambient Temperatures
TIN NO.
TIN-19-13-001
AFFECTED VEHICLES: 2018 – 2019 Eclipse Cross
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.
