ok just finished with my head gasket job and have a few codes.
ok on the koeo test first code i get is 11, all good. a lil later i get a 49, spout signal defaulted 10 deg BTDC, good the a 66, MAF sensor input below test min, i would think this is bad sensor.
on the koer test i get a code 21, ECT out of test range, well i really didnt warm it up all the way. then a code 91, leak HEGO left side, how does it know i may have a leak at the O2 sensor or is this the code for a bad O2 sensor? next a code 33, EGR not opperational, its disconnected. last i get a code 25, knock sensor not detected, i would guess that means i need a new knock sensor or wire is loose on the connector.
just would like to know if my guesses are right and i need to replace an O2 sensor, knock sensor, and mafs.
