Question

2004 Isuzu Rodeo 3.2L. what does code P1350 mean?

Answer 1

Circuit Description 
VVT (Variable Valve Timing) System controls the cam pulley phase to adjust the valve timing to the optimize timing.
The engine oil pressure controls VVT pulley.
OCV (Oil Control Valve) is located on front of the cylinder head and changes the pulley phase by changing the engine oil passage.
ECM controls OCV solenoid by PWM signal to adjust the phase to the target.
This code detects that a difference of target angle and actual angle larger than a threshold.

IMPORTANT: If DTC store caused by OCV sticks by the contamination, the self recovery works in the middle of the normal driving cycle. This is executed to take out the contamination from OCV. This may resolve the OCV stuck problem.
