Description
The MPEM indicates that the diagnostic function that you initiated was running, but suddenly failed during the execution.
Possible causes
| 1. | The MPEM input sensor is out-of-range. |
| 2. | The MPEM output driver circuit failed. |
| 3. | The target component is defective. |
| 4. | The software inside the MPEM failed. |
Suggested actions
| 1. | Make sure that the input value is within a valid range. |
 | If you are resetting the closed TPS, then make sure that the idle speed screw is in contact with the throttle plate stopper and try the command again. |
| 2. | Make sure that the target component is not defective. |
