Electric/Auxiliary Transmission Fluid Pump Motor Torque Out Of Range
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 motor torque required by the auxiliary transmission fluid pump is outside the calibrated window for the commanded duty. Pump load too high or too low for expected operation.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

Many vehicles show no symptom at all beyond the warning light. The absence of a symptom does not mean the fault is not real.
| # | Cause | How often | Component |
|---|---|---|---|
| 1 | Pump internal wear changes torque demand | Very common | — |
| 2 | Fluid viscosity outside spec | Common | — |
Ordering reflects how often each cause is responsible in general, not a probability for your vehicle. Confirm by testing.
