Reset ASC light?

[Ferret]

The ASC light will stick on for a few reasons - if it's throwing a specific code for the throttle body actuator - it may well be the little sensor on the other side of the throttle body that's toast.

Grab a multimeter and check it out :)

The ASC light resets itself the next start it detects there's nothing wrong with the system.

Test item 10 with a multimeter:

Pull off the trunking (part 3) peer inside the manifold and get someone to switch on the ignition - you should see the butterfly valve move to a mainly closed position and return to fully open fairly rapidly.

Hope this helps!

Hi,
I replaced my throttle body actuator with new one from BMA but light remains on. I had the codes read and shop claimed I needed a new throttle body actuator replaced with new one but light remains. Have probably started x40 times and disconnected battery to no avail....any ideas.

Have you checked to see if #16 has power?

Just throwing this out there, but is there a way the TPS's got switched. It will trigger the light & keep it on. Ask me how I know.
