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.
Diagnostic Aids
A high resistance condition on the throttle position and throttle actuator control circuits could cause a DTC to set.

Circuit/System Verification
1. Ignition ON, observe the DTC information with a scan tool. Verify DTC P06A3 is not set.
瀚慖f the DTC is set, refer to DTC P0641, P0651, P0697, or P06A3 (LF1) (See: P Code Charts/P0641/ECM).
2. Ignition ON, observe both Throttle Position Sensor voltage parameters with a scan tool. Verify the scan tool Throttle Position Sensor 1 and 2
parameters are between 1.0-4.0 V.
3. Perform the scan tool Throttle Sweep Test while observing the Throttle Position Sensors 1 and 2 Agree/Disagree parameter. The parameter
should display Agree.
4. Observe the DTC Information with a scan tool. DTCs P0121, P0122, P0123, P0222, P0223, and P2135 should not set.
