I replaced cam sensor bank 1 sensor a and no change, checked resistance of both cam vvrt actuators and both at 7.2 ohm which is same as new. Replaced bank 1 vvt actuator a and so far seems to be fixed
-
Light back on 20 miles. Needs timing chain at 78k and not on the extended warranty
-
Does anyone know the camshaft sensor location for a Cadillac SRX 2010? Also, is there a fuse related to this sensor? Thanks
-
For your 2010 Cadillac SRX, the P0016 code is for the "Crankshaft Position Sensor - Intake Camshaft Position Not Plausible Bank 1".
I have attached and image of the Intake Camshaft Position Bank 1

Thanks! I am getting a p0016 and p0017 code. I respond when I have more information or if fixed
-
Put in sensor in that position(#8 on link below) but still getting reading for p0016 and p0017. So probably other sensor won't make a difference.

If you have both codes and the sensor didn't fix the problem, then you may have a problem with the timing chain or timing chain tensioner. Unfortunately, the timing chain and tensioner can prematurely fail on this vehicles.
