P2080: Exhaust gas temperature sensor reading out of range (bank 1, sensor 1)

The exhaust temperature reading does not match what the ECU expects. An ageing sensor, an exhaust leak or the connector are common causes.

What P2080 means

The exhaust gas temperature sensor watches exhaust heat to protect the turbo, catalyst or particulate filter, and to manage regenerations on diesels. The signal is there but does not fit the driving conditions or the readings from other exhaust sensors, or it changes too slowly. Sensor 1 is the one closest to the engine; exhaust temperature sensors are numbered by their order along the pipe, and what sits between them (turbo, catalyst, filter) is up to each manufacturer.

Most common causes

  • Sensor connector dirty or corroded by heat
  • Exhaust leak near the sensor skewing the reading
  • Aged sensor responding slowly
  • Sensor fitted in the wrong position after a repair
  • Heat-damaged wiring

Symptoms

  • Engine warning light on
  • Particulate filter regenerations may stop taking place
  • Possible loss of power or limp mode

Can you drive with P2080?

With care You can drive with care, but without this reading the engine may limit power or skip particulate filter regenerations, leading to a clogged filter. Get it fixed soon.

How to check it

With a cold engine that has stood for a while, the live sensor temperature should be close to the ambient temperature and to the other exhaust sensors. Once driving, it should rise steadily.

How to read and clear P2080 with Final OBD

Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2080 with this same explanation and whether it’s confirmed, pending or permanent.

With Free you read this code with its short description for nothing, and clear it if the engine stores it over standard OBD. With Pro you get the full explanation, how the car was running when it was logged (revs, temperature, load) and clearing in every control unit.

Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before the ITV. It’s all in how to read and clear fault codes and in the ITV and OBD.

P2080 is a generic code, so it means the same on any make, for example on Audi, Fiat, Kia, Mazda, Opel / Vauxhall, Toyota. See what Final OBD does on your car in makes and models.

How do you clear P2080?

With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P2080 comes back.
