2011 Chevy Traverse P0008 code
Asked by Alan May 20, 2018 at 11:06 AM about the 2011 Chevrolet Traverse LS FWD
Question type: Maintenance & Repair
My vehicle has 124K miles on it it now. , The check engine light keeps coming
on a day after we had it it reset. P0008 error code. I already replaced the timing
chain at 100k miles(had to). Do you think i should have them check the timing
BELT, as it's the original. I need to do a 480 mile round trip to upstate NY in
August. Do you think I'll make it there?! Thanks

This information comes from my GM Shop Service Manual, Revised November 2014: "Code P0008-the Engine Control Module (ECM) tests for misalignment between both camshafts on one bank of the engine & the crankshaft. The misalignment would be at an idler sprocket for either bank or at the crankshaft. Once the ECM learns the position of both camshafts on one bank of the engine, the ECM compares the learned values to a reference value. The ECM will set a DTC if both learned values for one bank of the engine are exceeding a calibrated threshold in the same direction". Technician should check for: Stretched timing chain, Crankshaft reluctor wheel has moved and is no longer referenced with top dead center (TDC), Timing chain tensioner problem. I would have the vehicle checked again before taking the trip, just to be sure everything is fine. And, no, no one can assure you that you will make it there, other problems may come your way; but I do wish you the best!
Thanks Jorge! Can i just add that I had to get a new timing chain just after the car hit 100k. Also back in Febuary, I was driving back from Florida and low oil pressure light- stop engine was blinking. Had to get to new sensors- camshaft sensor and crank sensor, I think. What about the possibility of oil pressure sensor/and or switch needs replacement? My mechanic clean of the oil sensor yesterday reset the check engine light and it came back on today!
Well, I would replace the sensors even if your mechanic clean them. I have learned that new cars tend to mislead you with all the electronic components and warning signals. Diagnosing any problem in my 1957 Ford Fairlane is the easiest thing possible, but the times of the Saturday mechanic are gone for ever.....sadly!
