P1409 - EGR VACUUM REGULATOR (EGRVR) SOLENOID CIRCUIT MALFUNCTION
| Description: | This test checks the electrical function of the EGRVR solenoid. The test fails when the EGRVR circuit voltage is either too high or too low when compared to the expected voltage range. The EGR system must be enabled for the test to be completed. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | The EGR vacuum regulator solenoid resistance is between 26 and 40 ohms. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| Vehicles with an EGR system module (ESM) | GO to HH: Exhaust Gas Recirculation System Module (ESM) STEP HH21. | ||
| All others | GO to HE: Exhaust Gas Recirculation (EGR) Systems STEP HE59. | GO to HE: Exhaust Gas Recirculation (EGR) Systems STEP HE59. | GO to HE: Exhaust Gas Recirculation (EGR) Systems STEP HE64. |
