Monitor Description
WARNING: This page is about a different variant/trim than selected.
The ECM uses the throttle position sensor to monitor the throttle valve opening angle.
- There is a specific voltage difference expected between VTA1 and VTA2 for each throttle opening angle.
- If the difference between VTA1 and VTA2 is incorrect, the ECM interprets this as a fault and will set a DTC.
- VTA1 and VTA2 each have a specific voltage operating range.
- If VTA1 or VTA2 is out of the normal operating range, the ECM interprets this as a fault and will set a DTC.
- VTA1 and VTA2 should never be close to the same voltage levels.
- If VTA1 is within 0.02 V of VTA2, the ECM interprets this as a short circuit in the throttle position sensor system and will set a DTC.
