DTC P2228: Notes
DTC P2228 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2228 |
EGR boost sensor circuit low Input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the EGR boost sensor. If the input voltage at PCM terminal 1AL is 0.35 V or below
, the PCM determines that the EGR boost 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
- Open circuit between EGR boost sensor terminal C and PCM terminal 1AZ
- Short to ground circuit between EGR boost sensor terminal A and PCM terminal 1AL
- PCM malfunction
