Exhaust Gas Temperature Sensor Circuit High (Bank 1 Sensor 2)
The EGT sensor at bank 1 position 2 reads above the upper limit. Usually a short to supply, an open ground or a sensor that drifted high — risk of false DPF over-temperature limp.
Affected components
- Egt sensor
- Egt wiring
Common causes
- High likelihood: Signal wire shorted to supply
- Medium likelihood: Sensor drift to high reading
- Low likelihood: Connector pins corroded - high contact resistance
