Check engine light is on. Code P0524 for oil pressure too low. We need to diagnose this system and find out why the oil pressure is too low. Inspect the oil pressure sensor, oil temp. sensor, and oil pressure solenoid valve. Removal of the oil pan and eventually replace the timing chain driven oil pump. There is quite a bit of diagnostics in this one as we try to follow the flow chart and perform all of the steps to try and see what's goin' on.
