Why is there a warning light on my diesel engine?
Some diesel-powered cars have a specific warning light for their diesel particulate filter (DPF), whereas others don’t and rely on the EML providing a warning instead. The latter is sometimes also illuminated if the car detects a fault with the differential pressure sensor, which determines how effectively the DPF is performing.

Do you need an engine warning light to pass Mot?
The answer to this is ‘no’ – the light itself isn’t but the issue that causes could prevent your car passing its MoT depending on what it is. Unlike many of a dashboard’s other warning lights, an engine warning light doesn’t alert you to a specific fault.

It sends data to the vehicle’s computer, which uses it to regulate the mixture of air and fuel that enters the cylinders. An engine will keep running even if an O2 sensor needs to be replaced, but it will burn more fuel than usual. In the long run, a bad O2 sensor can damage components like the spark plugs and the catalytic converter.
Why does my GM car have a reduced engine power warning?
Some GM vehicles will enter Reduced Engine Power Mode when the engine begins to overheat due to cooling system issues. The PCM triggers the mode to protect the engine from further damage. In some instances, the Reduced Engine Power warning may illuminate to inform the driver that the vehicle lacks power due to an underlying condition.
