Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not drive around reduced-power throttle warnings; low redundant-channel signals can trigger safety strategies.
Useful checks before replacing parts
- Check sensor B reference voltage, ground, signal return, connector terminals, and harness damage.
- Compare sensor B against sensor A and commanded throttle angle while slowly moving the throttle or pedal.
- Watch live data while moving the harness to expose intermittent low-signal drops.
