 | Codes Hello everyone, I have a 2006 Envoy, w/ the 4.2 l6, Ses light came on checked for codes with a friends scan tool before i bought my own, replaced the map sensor after determining it was faulty, truck runs better but still seemed to shake a little. Yesterday the SES light went off by itself, i did not clear it with the scan tool. I rescanned it, and came up with PO506 , and PO106. Any help with this would be appreciated,thanks  |
