Microdiesel | EGR valve statusThis function allows the EGR status to be read and the operation of the valve to be checked. The EGR valve status is indicated in a list with a status number. |

Procedure
|
Background Check | List the parameters :Use this list to compare with the indicated value. STATUS : NoneNo EGR shutoff, the EGR operates normally according to the DCU programming. STATUS : 1, 5, 6, 7, 9, 10, 12, 13, 15, 19, 23, 24Switch off the ignition and wait for 1 minute. Switch the ignition on and check for faults. Check the battery voltage, engine stopped and engine running. If there is no fault code flagged or memorised, restart the vehicle and check the idle speed. Do not rev the engine to not run it too fast. STATUS : 3, 14, 16Accelerate to above idle for a few seconds. STATUS : 2Check that the clutch pedal is fully up and that the vehicle is stationary. STATUS : 4, 17Check for any fault codes present and recorded and correct them. STATUS : 8Reset the EGR offsets by using the command “Programming reset" and select "EGR valve". STATUS : 11, 22Allow the engine temperature to rise until the out of service setting disappears. STATUS : 18Check that the DPF regeneration running has been fully completed. STATUS : 20Allow the engine temperature to fall until the out of service setting disappears. STATUS : 21Atmospheric pressure too low, the EGR valve is deactivated To help isolate the cause of an EGR-related problem with the valve, passages, or control system, follow the recommended procedures below: If normal results were obtained, the EGR-related problem is being caused by a malfunctioning control system (vacuum-operated valves only). For electro-mechanical valves, a normal result indicates that the EGR-related concern is intermittent, check for stored fault codes with diagnostic equipment. If there is no change in idle quality, then either the EGR valve is inoperative or the EGR passages are completely restricted. A slight change in idle quality is indicative of partially clogged passages. |
