Vehicle with 30k miles (bought new and with regular oil changes) throwing p0018's intermittently. No noticeable difference in way the car drives: idling seems normal, fuel consumption regular, no power problems 0-50mph (I haven't taken it above 50 since the problem code first appeared.) There has been a slight engine tapping sound at low speeds only heard until the engine warms up after a couple of miles (I'm in Florida, temp is regular in the 70-80's), and the sound is not evident during the start-up, only while accelerating slowly.
Brought to dealer who, same day, requested doing an oil/filter change (I had done a change 900 miles/3 months prior) claiming that a wrong oil filter could cause blocked oil galleys. They did the change, repaired a valve cover leak and 6 days later called to tell me the car was fine. No mention of the car having been low on oil or evidence of sludging. Also, no mention of whether or not the filter that was replaced was the incorrect filter for the vehicle.
6 miles from the dealer after pickup (2 key turns) CEL returns, with same code. I have now driven the car about 160 miles in the last month with the CEl going off and on 6 times now, and each time the same code, p0018. The longest the CEL has stayed off was for a 30 mile span, typically returns after 10-15 miles. The CEl stays on for 3-6 key turns before going off. The tapping sound mentioned above continues too.
I've read up on the p0018 and it would seem that the initial dealership check using their GDS found nothing
except possible blocked oil galleys, hence the oil change. The p0018 could indicate a lot of different problems, but what could be causing only intermittent CEL p0018's (or intermittent CEL in general)? If the CEL stays on for an extended period again, I'll be returning to the dealer.
have the same problem?
