DTC P0222
DTC P0223
TPS2 sensor sends signal through ECT harness connector EO27 terminal C to ECM through ECM harness connector EO01 terminal
No.26. If the TPS2 sensor signal is lost, ECM is still able to receive the normal TPS1 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.
