DTC P2227: Notes
DTC P2227 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2227 |
EGR boost sensor circuit performance problem |
| DETECTION CONDITION |
- The PCM monitors the differences between the intake manifold vacuum and atmospheric pressure at idle, which the EGR boost sensor detects by switching the EGR boost sensor solenoid. If the difference is 6.4 kPa {48 mmHg, 1.9 inHg} or below
, the PCM determines that there is a EGR boost sensor performance problem.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available 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 or substandard performance
- EGR boost sensor solenoid valve malfunction
- Loosed, damaged, misconnected, clogged or frozen moisture in vacuum hose from EGR boost sensor solenoid valve to EGR boost sensor
- Loosed, damaged, misconnected, clogged or frozen moisture in vacuum hose from EGR boost sensor solenoid valve to EGR pipe
- PCM malfunction
