Vectra Diesel Intake Air Temperature Sensor Fault

My 2004 Vauxhall Vectra diesel is having engine trouble. Check engine light is on and power is reduced. Diagnostics show an intake air temperature error and the engine runs rough. Could a faulty intake air temperature sensor be the problem?

I also drive a Vectra diesel and had a similar issue recently. Your symptoms sound familiar. Did the diagnostics tool give a specific error code for the temperature reading?

Yes, the diagnostics indicated a faulty intake air temperature sensor, suggesting implausible values. What fixed it for you? Did replacing the sensor solve it?

Replacing the sensor fixed it. Considering the error code and your symptoms, I'd suggest getting the sensor replaced at a workshop. It's probably defective.

Thanks! Took it to a workshop and they confirmed the sensor was faulty. Replaced it for 155€. Seems to have solved the issue.
