DTC P0222-00: TP Sensor No. 2 Circuit Low Input: Notes

DTC P0222:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0222:00	TP sensor No. 2 circuit low input
DETECTION CONDITION	If the PCM detects that the TP sensor No. 2 voltage at the PCM terminal 1BE is below 0.1 V, the PCM determines that the TP 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	Restricts the upper limit of the engine speed.
POSSIBLE CAUSE	Throttle body connector or terminals malfunction Short to ground in wiring harness between the following terminals: Throttle body terminal E-PCM terminal 1CB Throttle body terminal D-PCM terminal 1BE PCM connector or terminals malfunction TP sensor No. 2 signal circuit and ground circuit are shorted to each other Open circuit in wiring harness between the following terminals: Throttle body terminal E-PCM terminal 1CB Throttle body terminal D-PCM terminal 1BE TP sensor No. 2 malfunction PCM malfunction
