5. Repair Instructions:
Replace the engine coolant temperature sensor. Refer to
2.12.7.21 DTC P0122 P0123
1. DTC Descriptor:
DTC P0122
DTC P0123
TPS1 sensor sends signal through ECT harness connector EO27 terminal B to ECM through ECM harness connector EO01 terminal
No.39. If the TPS1 sensor signal is lost, but ECM is able to receive the normal TPS2 sensor signal, then ECM controls the engine
enter "reliability of determining the driver's intention decline or no high power output mode". Engine responds to the pedal changes
slow and engine power output will be significantly weaker, although the vehicle can still be able to driving in normal traffic.
