2012 yaris 1.33 engine knocks down when i turn it off

Morning guys,

Just bought a 1.33 2012 Yaris and when I shut the car off it sounds like a diesel. Clatters on shut off for about 2/3 seconds.

Anyone else experienced this, is this normal for that engine or have I got a problem

Thanks

Joe

I'm not familiar with the 1.3L, but that is very odd for an injected motor to "run-on" or "diesel". Odd enough that I've never seen it on an injected motor in 20yrs of dealing with cars. If it is dieseling, it means you have both fuel and ignition. Fuel could be leaking injector as mentioned, or engine oil. Ignition could be hot carbon deposits or valves. High idle RPM also contributes as it makes it easier for the engine to keep going. At the end of this (loud) video, there is an example of what dieseling looks like: https://www.youtube.com/watch?v=uv1tgSWWlHQ

It could also be something totally different in that maybe one circuit of the ignition switch is not turning off. So maybe your ECU is still powered and commanding it to run, but the fuel pump has shut off. You would expect to have some obvious electrical problems at the same time though.

Cheers.
