P2080 Exhaust Gas Temperature Sensor Range/Performance (Bank 1 Sensor 1)
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.
Is it safe to drive with P2080?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySensor aged — slow response
- PossibleSensor tip soot-fouled
- Less likelySensor element aged beyond calibration window
