Hi, I have a 2012 Santa Fe with a 3.5L engine and about 213,000 miles on it. Yesterday it threw all four of the camshaft position over-advanced codes p0011, p0014, p0021 and p0024. I know it would be pretty unusual for all the sensors to go bad at the same time, so is it possible if one the sensor goes bad can it cause the other codes to set also? I changed the oil and filter today but that didnt help. What else could cause these four codes to be set at the same time? Also, while I was checking the codes I noticed on the Readiness Monitor that the catalytic and evap monitors didnt set. Is it possible that its related to the t camshaft timing codes?
Does anyone have any idea whats going on with these codes? Thanks for any help you can offer.

 

The best way to approach this is to start at the beginning and that is to verify the timing marks all line up as required. There is a good possibility the belt may have slipped.
Until that is done, we are always starting in the middle overlooking something we should have verified before going this far.

 

UPDATE- After driving the car about 20 miles the check engine light went off and no longer sets any of the codes. Im assuming after changing the oil the oil needed to circulate through the system to clear out any gunk in the sensors.
