DTC P2127-00: App Sensor No. 2 Circuit Low Input: Notes

DTC P2127:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2127:00	APP Sensor No. 2 Circuit Low Input
DETECTION CONDITION	The PCM monitors the input voltage from APP sensor No. 2. If the input voltage at the PCM terminal 2BB isless than 0.1 V, the PCM 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 PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Regulates the upper limit of the APP sensor output.
POSSIBLE CAUSE	APP sensor connector or terminals malfunction Short to ground in wiring harness between the following terminals: APP sensor terminal F-PCM terminal 2AO APP sensor terminal E-PCM terminal 2BB PCM connector or terminals malfunction APP sensor No. 2 signal circuit and ground circuit are shorted to each other Open circuit in wiring harness between the following terminals: APP sensor terminal F-PCM terminal 2AO APP sensor terminal E-PCM terminal 2BB APP sensor No. 2 malfunction PCM malfunction
