Throttle Actuator B Control Module Performance
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The throttle control module on the B path reports general performance issues — internal fault, communication mismatch, or calibration drift.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
- Safe to drive

Many vehicles show no symptom at all beyond the warning light. The absence of a symptom does not mean the fault is not real.

|---|---|---|---|
| 1 | Internal module fault | Very common | — |
| 2 | Module software outdated, reflash may resolve | Occasional | — |
