Diagnostics |
A short circuit on the 5V supply will put the throttle in limp-home mode and can be caused by a fault in the wiring harness or a sensor supplied with 5V. As the two 5V supplies are internally coupled in the throttle housing, no symptoms will appear if there is a break in just one of them.
