DTC P2127-00: Throttle/Pedal Position Sensor/Switch "E" Circuit Low [08/2018 - ]: Contents

DTC No.	Detection Item	DTC Detection Condition	Warning Indicate	Memory	Fail-safe Operation	Note
P212700	Throttle/Pedal Position Sensor/Switch "E" Circuit Low	APP sensor No. 2 circuit low input	Check engine light: ON Master warning light: OFF Charging system warning light: OFF Engine oil warning light: OFF Wrench warning indicator light: OFF	DTC stored	Applicable	Drive cycle: 1 Monitor item: CCM Self test type: CMDTC self test, KOEO self test, KOER self test

200 PIN TYPE

DTC DETECTION CONDITION	APP sensor No. 2 circuit low input
DTC DETECTION CONDITION	The ECM monitors the input voltage from APP sensor No. 2. If the input voltage at the ECM terminal A42-43 is less than 0.1 V, the ECM determines that the APP sensor No. 2 circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the ECM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 02)/Snapshot data is available. DTC is stored in the ECM memory.
FAIL-SAFE OPERATION	Regulates the upper limit of the APP sensor output.
TROUBLE AREA	APP sensor connector or terminals malfunction Short to ground / open circuit in wiring harness between the following terminals: APP sensor terminal E7-6-ECM terminal A42-29 APP sensor terminal E7-5-ECM terminal A42-43 ECM connector or terminals malfunction APP sensor No. 2 signal circuit and ground circuit are shorted to each other APP sensor No. 2 malfunction ECM malfunction

186 PIN TYPE

DTC DETECTION CONDITION	APP sensor No. 2 circuit low input
DTC DETECTION CONDITION	The ECM monitors the input voltage from APP sensor No. 2. If the input voltage at the ECM terminal A43-70 is less than 0.1 V, the ECM determines that the APP sensor No. 2 circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the ECM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the ECM memory.
FAIL-SAFE OPERATION	Regulates the upper limit of the APP sensor output.
TROUBLE AREA	APP sensor connector or terminals malfunction Short to ground / open circuit in wiring harness between the following terminals: APP sensor terminal E69-6-ECM terminal A43-55 APP sensor terminal E69-5-ECM terminal A43-70 ECM connector or terminals malfunction APP sensor No. 2 signal circuit and ground circuit are shorted to each other APP sensor No. 2 malfunction ECM malfunction

NOTE:

186 Pin Type
Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
