The light service engine lite comes on. I had it fixed about a month ago. Was on a trip and the light came on again. Checked all fluids and they were fine. This costs quite a bit of money.
Check engine light stays on. Have reset it about 5 times and will still come back on
Same issue with Throttle Positioner being dirty or worn in conjunction with the Mass Air Flow Sensor failure. There were conflicting error codes when the check engine light came on causing me to change both components at the same time.
