P2127 - Throttle/Pedal Position Sensor/Switch E Circuit Low

4-124 Powertrain DTC Charts and Descriptions

Diagnostic Trouble Code (DTC) Charts and Descriptions

P2127 - Throttle/Pedal Position Sensor/Switch E Circuit Low

Description: This DTC sets when the accelerator pedal position 2 (APP2) is out of self-test range low.

Possible Causes: • APP2 circuit open

• APP2 circuit short to ground

• Damaged APP sensor

Diagnostic Aids: An APP2 sensor PID reading may indicate a concern.

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test DK.

P2128 - Throttle/Pedal Position Sensor/Switch E Circuit High

Description: This DTC sets when the accelerator pedal position 2 (APP2) is out of self-test range high.

Possible Causes: • APP sensor assembly is binding

• APP2 circuit short to voltage

• Damaged APP sensor

Diagnostic Aids: An APP2 sensor PID reading may indicate a concern.

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test DK.

P2135 - Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation

Description: This DTC sets when the PCM indicates that throttle position (TP) voltage PIDs TP1 and TP2 disagree by

greater than a calibrated limit.

Possible Causes: • Corrosion

• Incorrect connections

• Damaged TP sensor

Diagnostic Aids:

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test DV.

P2138 - Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation

Description: The PCM compares the accelerator pedal position (APP) sensor information from APP1 and APP2 signals. This

DTC sets when the APP sensor inputs APP1 and APP2 disagree on the position of the accelerator pedal by greater than an expected value.

Possible Causes: • APP sensor circuit concerns

• Damaged APP sensor

Diagnostic Aids:

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test DK.

P2195 - O2 Sensor Signal Biased/Stuck Lean - Bank 1, Sensor 1

Description: A heated oxygen sensor bank 1, sensor 1 (HO2S11) indicating lean at the end of a test is trying to correct for an

over lean condition. This DTC sets when the fuel control system no longer detects switching for a calibrated amount of time.

Possible Causes: • Water in the harness connector

• UO2SPC11 circuit open (if equipped)

• HO2S11 circuit open (if equipped)

• Corrosion

• Incorrect connections

• Low fuel pressure or running out of fuel

• EVAP purge valve stuck open

• Biased MAP sensor signal (if equipped)

• Incorrect learned ethanol content
