2008 saturn vue 3.6L p0014 p0496 p0174

Postby amtek1 » Sun Apr 17, 2016 3:10 pm

Was driving home from a job when the car started running rough (out of time). My scanner came up with P0014 P0496 P0174. Thought maybe the first code affecting the other two and replaced the Bank 1 intake and exhaust cam position actuators. Upon start up, car ran great. When the car was driven and warmed up, started running rough again. This was the case before replacing actuators, as well. Now I get DTC's P0011, P0014, P0024, P00174. Seems that things got worse. Runs fine cold and then when up to temp, it falls apart. No solution found online. Any information is appreciated. Thanks.

you replaced the cam solenoids - or the actual actuators on the cam shafts? I suspect the solenoids am I correct? Bank 1 is R/S....
this system is dependent on oil pressure, be sure to ck oil level, quality, clean, and finally pressure. Often sludge gunk affect the solenoids movement, also ck for a grounded wire to solenoids...
I often advise a can/bottle of " RISOLONE" an oil detergent to clean the oil passages up...

I agree work the VCT issue first...

Thanks for fast response. This site is definitely bookmarked. I replaced the solenoids. When I removed the cam position sensors, they were gummed up and filthy. I bought the car for a work vehicle with 79,000 miles on it. Looked good. Carchex looked good. I put all hiway miles on it. Miles read 208,000. I keep the engine oil changed on a regular basis (5000 mile intervals). If the sensors were filthy and gummy, what are the chances that the actuators are gummed up. What can be done to clean them. You mentioned an additive. Do you have good results? Thank you, so much!

Kev2 ... Just an hour before replacing the solenoids, I changed the oil and filter. What should the oil pressure read? And lastly, why would the engine run great until it got to full operating temp. Usually after 15 min. Thanks, again.

let me try and answer your concerns...
>>"what are the chances that the actuators are gummed up."
At 208K miles, Don't know BUT the product mentioned is @<10$ and will address issue, try it.
>>"What should the oil pressure read?"
You cannot trust the dash gauge, a mechanical gauge will need to be utilized. lets hold off.
>>"why would the engine run great until it got to full operating temp"
Often the computer is NOT controlling and adjusting until in closed loop - temp and time determine when it "takes over"
>>"You mentioned an additive. Do you have good results?"
RISOLONE is a product I have used for a long long time to help with sludge/gum issues and I have good results and NO adverse issues...

There is a BIG BIG difference between reading codes and using a scanner - the professional scanner will interface with vehicle computer allowing the tech to see live data & control those computer controlled devices. Relevant here We can view timing the relationship between cam and crank timing offset, this checking chain, tensioner, etc for causing an issue . SO-
We are NOT done working this yet. I am a hopeless optimist. :)
Try the suggested Hail Mary - I will look up the oil pressure specs and we will go on after the detergent has a few miles to (hopefully) work.
