Broken under bonnet Sensor

t_rage · 03-07-2016, 11:03 AM

Hi, just got the my father's 1991 Supra out of the garage and got it running after about 4 years. Noticed that one of the sensors under bonnet had aged and broken off from the female engine side.

The engine is running OK but very rich and there is a slight backfiring that can be heard inside from the exhaust at idle.

Had a look on the site and can't find anything about a particular under bonnet sensor. Can anyone identify? Thanks.

That's a really clean 7M you have there, but I can't tell for certain from your photo which sensor is broken. Here's a pic which might help you identify what you're looking for...

And another from a slightly different angle...

Ah thanks for the info. I can see it from the first pic labelled cold start injector time switch.

I guessing since we're past the worst if the winter and it starts fine I don't need this for immediately. Would anyone know if this would effect engine running once started? I'm guessing no.

Thanks all.

Nope. It's simply to provide additional fuel for a cold start, only time (to the best of my knowledge) it functions. I'd pick up a replacement from a junked car somewhere.
