P2081: Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 1 Sensor 1)
Standardized SAE J2012 code · P20xx — Fuel & air metering and auxiliary emission controls
What does P2081 mean?
The EGT sensor at bank 1 sensor 1 signal jumps or drops out intermittently — typically a connector or chafed wire near the exhaust manifold heat zone.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Connector loose or oxidised
- Medium Wire chafed against exhaust shielding
- Low Connector with intermittent contact under vibration
Likelihood is a general estimate across vehicles; your make and model may differ.
