2003 GMC Envoy Question: map sensor
Hi If you have a 5.3 it's located on the top of the intake at the back and the connector is a 3 way connector. If it's a 4.2 it's located center top of intake at the back and also has a 3 way connector. Hope this helps or let me know if you need more info. RJ - Auto Stop Limited
It is running rough, set off warning light code replace MAP Sensor. It says I should try cleaning and replace before replacing the new sensor. I know nothing but...
Twice in 2 years, I have replaced the MAP sensor, and the problem still exists. What else could I try besides changing sensor?
need advice where to troubleshoot first and where the map sensor is on this vehicle. 2004 gmc envoy xuv
