P2AD7Reductant Pump Motor Position Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2AD7 sets when the motor position signal of the reductant pump is electrically valid but does not fit what the pump should be doing, for instance a rotor position or derived speed that is out of step with the commanded drive pattern. No maker documents P2AD7 publicly. Ford's 2023 diesel summary shows a related check from the speed side: P208B, the pump control performance code, fails when pump speed deviates from its setpoint by more than 300 rpm or the speed controller sits at its limit for 30 s. A stiff or partly frozen pump, crystallised DEF in the pump head or a shifted sensor magnet can all produce such mismatches. Because most pumps are sealed units, a confirmed P2AD7 together with pressure codes usually ends in a pump module replacement.
- What you may notice
- Check engine light and SCR warning
- Pressure build-up of the DEF system fails, often after cold nights
- Likely causes
- LikelyPump stiff or partly frozen, crystallised DEF in the pump head
- PossiblePosition sensor inside the pump giving a shifted signal
- RareController software needing an update
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
