Powertrain
generic / SAE
P262D
Sensor Reference Voltage G Circuit Low
The 5 V reference G voltage is below the expected level. Usually a short to ground or excessive load from a downstream sensor pulling the rail down.

Possible causes
- Reference wire shorted to ground high
- Sensor on the rail shorted internally to ground medium
- Connector pins corroded - high contact resistance low
Inspection / repair
- Difficulty: medium
- DIY: shop recommended
- Estimated cost: 120–1200 €
- Estimated time: 0.8–4 h
- Component: control module
- Component: reference voltage rail
- Component: sensors on rail g
- MIL / check engine light
