Leakage Flow Over Throttle

Measurement range 0-655 kg/h.

The value indicates how much air passes through the throttle at closed throttle position (CTP). The engine control module (ECM) calculates the value from the mass air flow (MAF) sensor and the throttle position (TP) sensor signals.

The normal value is approximately 5 ± 4 kg/h.

NOTE:

Other values apply if there is air leakage on the intake system.
