Throttle/Fuel Inhibit A Circuit Range/Performance
The throttle/fuel inhibit A signal is electrically intact but its value does not match the system context — for example asserted while the immobilizer reports OK, or de-asserted while a hybrid HV interlock is active. The ECM cannot trust the signal.
Affected components
- Throttle inhibit a
Common causes
- High likelihood: Requesting module sending an inconsistent value
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
Diagnostic notes
