P2080: Exhaust Gas Temperature Sensor Range/Performance (Bank 1 Sensor 1)
Standardized SAE J2012 code · P20xx — Fuel & air metering and auxiliary emission controls
What does P2080 mean?
The pre-catalyst EGT sensor on bank 1 returns a value that does not match the expected temperature curve under load. Often slow response time after long service life or a contaminated tip.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Sensor aged — slow response
- Medium Sensor tip soot-fouled
- Low Sensor element aged beyond calibration window
Likelihood is a general estimate across vehicles; your make and model may differ.
