Throttle/Fuel Inhibit B Circuit Range/Performance
Throttle/fuel inhibit B signal reads in range but plausibility fails — does not assert/release as expected.
Affected components
- Throttle fuel inhibit
Common causes
- High likelihood: Inhibit logic mismatch
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
