I just got my oil changed today and when I started my car to leave the dealership a CEL came on. I made them come out and check it since my car was absolutely perfect before I went in and no CEL. They took it back into the shop and about 5 minutes later they came back and told me with a shrug "It's just some random SSV code and they cleared it. Nothing wrong with your car and it shouldn't come back on." I restarted the car and it was still on. I went back in and got them while the car was still running. The jackass at the service counter told me that if I wanted it to be looked at I'd have to make an appointment (I have one Friday morning). I asked for the number of the code and was told "Sorry, he didn't write it down so he has no idea what it was, but it was related to the SSV." Keep in mind it's been less than 10 minutes since they checked the code. They told me since it's the SSV code they'll likely need to replace the valve and the the price of the valve alone is $500 and then there's a labor cost (this should all be covered under the extended warranty I purchased which was for 7 years 84,000 miles and I have a 2006 with 78,000 miles on it so should only have to pay the $100 deductible). The timing sucks because I was supposed to go to DEQ next Wednesday and I can't with a CEL. Grrrrrrr!!!!!

So my question, shouldn't I be having some sort of symptoms of this valve acting up? I have no issues with starting, idling, power at any RPM range, sudden power loss, et cetera. The car still drives great with no problems. And also, why would it randomly appear after an oil change? Is there something else that could cause a CEL associated with an oil change? I'm wondering why they refuse to give me the code in the first place (I need to get it read somewhere since my code reader seemed to have vanished when I moved last year) and why I would suddenly have one after they changed my oil and washed my car with no prior symptoms. I drove my car the 10-ish miles home and absolutely no signs of anything being wrong, no weird noises or smells, et cetera. I was trying to test it being the SSV knowing symptoms include rough idle, power loss, and sluggish at high RPMs. I was able to redline it repeatedly with no issues, drive with higher RPMs the rest of the time, sit at stoplights with no rough idle. Absolutely no strange sounds with any of these things. I know it would be more helpful if I had the code, but any idea what might be causing the CEL given the circumstances and lack of symptoms surrounding it?

 

Okay, it is the P2070 code. Still confused as to how it appeared suddenly after an oil change and there are no symptoms of it. How do I check if it's the switch? I searched but basically found stuff about cleaning the SSV.

 

If I'm not mistaken, overfilling the oil or not using a funnel long enough will cause oil to seep into your intake from the hose going from your oil fill to the intake accordion tube due to the lack of a PCV valve. The oil and blow-by gasses can gunk up your SSV.

 

Now the code went away by itself after I drove around so more doing the rest of my errands. Hopefully it stays off tomorrow morning so I can at least try to go through DEQ before work. I figure I'll deal with the problem later if it comes back since I have no symptoms right now.

 

Thanks! I'll check on that!
