Electronic Control Module (ECM)
At engine speed > 900 rpm, the actual camshaft timing is compared to the estimated values.
VANOS inactive: Fault if timing is greater than ± 3° camshaft angle from estimated value.
VANOS active: Fault if timing is greater than ± 4.5° camshaft angle from estimated value.
