Exhaust Gas Temperature Sensor Circuit (Bank 2 Sensor 2)
A general electrical fault is reported on the exhaust gas temperature (EGT) sensor at bank 2 sensor 2 — open, short, or out of plausibility. EGT sensors monitor catalyst, DPF, and turbocharger inlet/outlet temperatures.
Affected components
- Exhaust gas temperature sensor
- Egt harness
Common causes
- High likelihood: EGT sensor element failed
- Medium likelihood: Open wire in EGT harness
- Low likelihood: Connector corroded by exhaust heat
