P06F2
Reductant Control Module Internal Temperature Sensor Circuit Low
Same as P06F0 with the signal voltage below the plausible range. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.

Possible causes
- Sensor internal short high
- Connector pins corroded - high contact resistance low
- Harness chafing through insulation low
Symptoms
- Check engine light or NOx warning on
- AdBlue/DEF level or quality warning
- Possible no-start countdown after ignore period
- Failed emissions inspection (NOx)
Inspection / repair
- Difficulty: medium
- DIY: shop recommended
- Estimated cost: 200–800 €
- Estimated time: 1–3 h
- Component: reductant control module
- MIL / check engine light
- emissions-relevant
