Thanks Eric I read through all of that, good info! I went back to the truck and cycled the selector back and forth then started the engine. Service 4wd light was gone and all selections operated normally...been good since. Hopefully just an intermittent isolated glitch lol

Update: Installed new ac delco camshaft position sensor Installed new ac delco camshaft position actuator solenoid due to oil in electrical plug Cleaned harness side of plug of all oil Removed throttle body and cleaned Pulled pcm fuses for relearn Code is gone and all good now!

My wife started the truck just now and saw the service 4wd light on the instrument panel. Also noticed no lights above the selector switch. I had her shut the truck down and rotate the selector a number of times left and right. Restart and service 4wd is still there and still no lights above...

New ac delco sensor and ac delco solenoid on the way. I'll report back once they are installed.

Thanks maverick!

Thanks for the pic. So when I unplugged it, I noticed a pool of oil in that part of the plug where the two pins are - same as in your picture. I stuffed Kleenex in there to dry it out.

Thanks Maverick. I kind of figured that the solenoid would throw its own codes if it was malfunctioning, so I'll stick with replacing just the cps sensor. Definitely getting a p0340 code and sometimes a dip in idle when coming to a stop. I did find a how to on pulling the solenoid so I'll...

I keep throwing a P0340 code which leads me to the camshaft position sensor. I am going to replace the original with an acdelco CPS: 2131557. Is it recommend to replace the camshaft position solenoid at the same time? I haven't had any codes related to the solenoid itself but, I did notice oil...

Thanks guys! Yeah I've always instructed her to use 4HI and only when the road conditions warrant ie, slippery roads in deep snow etc and then to switch back to 2HI again. For whatever reason during the last snow fall, she must have switched to A4WD and then forgot to switch back to 2HI, so I...

I just realized that my wife has been driving with the selector set to A4WD on dry pavement for several hundred miles.... Is this something that would cause damage or wear and tear? I realize that driving in 4HI on dry pavement is a no no because of the potential for damage but I wasn't sure...

Update: I brought the envoy in today to a friends shop and explained the issue. We recovered all of the refrigerant in order to see what the weight was. The system should hold .85kg and we recovered .61kg using a mactools ac diagnostic system. So it was a little low but not empty. Next we put...

It's going in next week to have the ac pressures checked. Just out of curiosity, is it possible for the system to lose charge overtime because of age only, or does there actually have to be a leak somewhere in the sealed system? Truck is 2003 with 130,000 miles Also, is it normal for the...

Yeah from what I could tell - and I think I tested it properly - the fan clutch seems to be working ok but as you mentioned, might be weak as the tugging was slight once the engine temp started to rise. I think it was just starting to pass the 210 mark when the tugging started. I had to let the...

Ok after a drive today I parked and let it idle. AC on. I was able to slow the fan down to a stop and easily hold it there. Didn't seem to be any fore and aft play. I let the fan go and it slowly spun up I tried slow it down again and I couldn't. I gave the engine a bit of gas and the fan...

It was all city driving so maybe 40mph for short period of time and then around 30 or so... I'll check the fan clutch and then have the AC pressures checked
