DTC P0122:00: Notes

DTC P0122:00 (L3 WITH TC) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0122:00	TP sensor NO. 1 circuit low input
DETECTION CONDITION	If the PCM detects that the TP sensor NO. 1 voltage is below 0.2 V after the ignition switch is turned to the ON position, the PCM determines that TP sensor NO. 1 circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. DTCs are stored in the PCM memory.
POSSIBLE CAUSE	Throttle body connector or terminals malfunction Short to ground in wiring harness between throttle body terminal B and PCM terminal 2AO PCM connector or terminals malfunction Open circuit in wiring harness between throttle body terminal B and PCM terminal 2AO Short to ground in wiring harness between throttle body terminal A and PCM terminal 2AK Throttle body signal circuit and ground circuit are shorted to each other TP sensor NO. 1 malfunction PCM malfunction

DTC P0122:00

TP sensor NO. 1 circuit low input

DETECTION CONDITION

If the PCM detects that the TP sensor NO. 1 voltage is below 0.2 V after the ignition switch is turned to the ON position, the PCM determines that TP sensor NO. 1 circuit has a malfunction.

Diagnostic support note

This is a continuous monitor (CCM).
MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
DTCs are stored in the PCM memory.

POSSIBLE CAUSE

Throttle body connector or terminals malfunction
Short to ground in wiring harness between throttle body terminal B and PCM terminal 2AO
PCM connector or terminals malfunction
Open circuit in wiring harness between throttle body terminal B and PCM terminal 2AO
Short to ground in wiring harness between throttle body terminal A and PCM terminal 2AK
Throttle body signal circuit and ground circuit are shorted to each other
TP sensor NO. 1 malfunction
PCM malfunction
