1D-4 Engine Mechanical: For M16A Engine with VVT Targeted Timing Varying Operation Diagnostic Information and Procedures Compression Check S5JB0A1414001 Check compression pressure on all 4 cylinders as 1) Warm up engine to normal operating temperature. NOTE
3) Disconnect ignition coil couplers (1). tension cord (3). 5) Remove all spark plugs. Driving condition Valve timing Target of control Effect Engine running at idle Most retarded To shorten the valve opening overlap in Stabilization of the engine Average engine load To the advanced To lengthen the valve opening overlap Improvement of the fuel Light engine load To the retarded side To shorten the valve opening overlap in Keeping of the engine stability. Low or average To the advanced To advance the closing timing of the Improvement of generating the High engine speed To the retarded side To retard the closing timing of the Improvement of generating the Low engine coolant Most retarded To shorten the valve opening overlap in Stabilization of the fast idling of At engine starting and Most retarded To shorten the valve opening overlap in Improvement of start ability.
