DTC P0222 00: TP Sensor No. 2 Circuit Low Input: Notes
DTC P0222:00 DETECTION CONDITIONS AND POSSIBLE CAUSES (SKYACTIV-G 2.0, SKYACTIV-G 2.5)
| 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 1 BU 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 defects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/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 B-PCM terminal 1BS
- Throttle body terminal C-PCM terminal 1 BU
- 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 B-PCM terminal 1BS
- Throttle body terminal C-PCM terminal 1BU
- TP sensor No. 2 malfunction
- PCM malfunction
