DTC P2229: Notes
DTC P2229 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2229 |
EGR boost sensor circuit high, input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the EGR boost sensor. If the input voltage at PCM terminal 1AL is 4.9 V or above
, the PCM determines that EGR boost sensor 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 is available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- EGR boost sensor malfunction
- Connector or terminal malfunction
- Short to power circuit between EGR boost sensor terminal A and PCM terminal 1 AL
- Open circuit between EGR boost sensor terminal B and PCM terminal 1BD
- PCM malfunction
