TYPICAL MALFUNCTION THRESHOLDS

Advance:

Both of the following conditions are met

-

(a) Deviation of valve timing

More than 5° CA (crankshaft angle)

(b) Valve timing

No change at advanced valve timing

Retarded:

Both of the following conditions are met

-

(a) Deviation of valve timing

More than 5° CA (crankshaft angle)

(b) Valve timing

No change at retarded valve timing

If the difference between the target and actual camshaft timings is greater than the specified value, the

ECM operates the VVT (Variable Valve Timing) actuator.

Then, the ECM monitors the camshaft timing change for 5 seconds.
