Q: P0018

asked by on April 12, 2017

I got the code p0018 on my scanner i changed the camshaft sensor already and i still get the check engine light

My car has 47500 miles.
My car has an automatic transmission.

Sensor output has to be directly tested (or the data/waveform viewed on a scanner) and determined to be faulty prior to replacement. If the sensor happens to test good then, the cause lies elsewhere. Code P0018 can set due to circuit problems on the sensor circuit and not necessarily a fault with the sensing element itself. There are also potential mechanical causes that have to be ruled out such as the bank No. 2 intake camshaft being out of position compared to the crankshaft position. The bank 2 camshaft phaser could be stuck in one position or will not move. The phaser might be oil starved due to the wrong oil viscosity and/or the oil control valve (OCV) could be stuck closed or open.
