Throttle Position, Circuit 1

The value indicates the actual throttle position. The signal comes from the directly connected position sensor, sensor 1, in the throttle unit.

Measurement range -3 - 130%.

0% = throttle is shut.

100% = throttle is fully open.

Normal value: Approx 12% corresponds to closed position, approx 80% corresponds to open position. (mechanical limit positions).

HINT: In a trouble-free system it is the position from the sensor in circuit 1 that is used by the Engine Control Module (ECM) for inter calculating and regulation. If the control module detects a fault with the sensor in circuit 1 the position from the sensor in circuit 2 is used instead.
