sensors with a common 5 V reference circuit, a common low reference circuit, and 2 independent signal circuits.



The TP sensors have opposite functionality. TP sensor 1 signal voltage decreases and TP sensor 2 signal voltage increases as the accelerator pedal



increases to wide open throttle (WOT).



Conditions for Running the DTC



P0121



* DTCs P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0335, or P0336 is not set.



* The engine speed is between 400-7,000 RPM.



* The engine coolant temperature (ECT) is between 69-127掳C (156-260掳F).



* The intake air temperature (IAT) is between -20 to +125掳C (-4 to +257掳F).



* The DTC runs continuously when the above conditions are met.



P0122, P0123, P0222, P0223



* DTC P06A3 is not set.



* The ignition is ON, or the engine is running.



* The engine is not operating in reduced power mode.



* The ignition voltage is greater than 6 V.



* The DTCs runs continuously when the above condition are met.



P2135



* DTCs P0121, P0122, P0123, P0222, P0223, or P06A3 are not set.



* The ignition is ON, or the engine is running.



* The engine is not operating in reduced power mode.



* The ignition voltage is greater than 6 V.



* The DTCs runs continuously when the above conditions are met.



Conditions for Setting the DTC



P0121



The ECM detects that the TP sensor 1 voltage is stuck in range for less than 1 s.



P0122



The ECM detects that the TP sensor 1 voltage is less than 0.3 V for less than 1 s.



P0123



The ECM detects that the TP sensor 1 voltage is greater than 4.8 V for less than 1 s.



P0222



The ECM detects that the TP sensor 2 voltage is less than 0.3 V for less than 1 s.



P0223



The ECM detects that the TP sensor 2 voltage is greater than 4.6 V for less than 1 s.



P2135



The ECM detects that TP sensor 1 and TP sensor 2 disagree greater than 7-10 percent for less than 1 s.



Action Taken When the DTC Sets



P0121



* DTC P0121 is a type B DTC



* The ECM commands the throttle actuator control (TAC) system to operate in a Reduced Engine Power mode.



P0122, P0123, P0222, P0223, or P2135



* DTC P0122, P0123, P0222, P0223, and P2135 are type A DTCs



* The ECM commands the throttle actuator control (TAC) system to operate in a Reduced Engine Power mode.



Conditions for Clearing the DTC



* DTC P0121 is a type B DTC.



* DTCs P0122, P0123, P0222, P0223 and P2135 is a type A DTC.
