So lets suppose, that an idiot was working on his car in the wee hours of the morning. He was having difficulties and was getting frustrated. The final outcome of his stupidity resulted in him accidentally breaking the plug on his air speed sensor at the bottom of the filter box. If this sensor was not plugged in, how would the car react?

Might it possibly start, rev to around 4 grand and the immediately fall back to 0 and dead? Or is that a symptom of some other thing that I, oops, I mean the idiot has created while destroying his car. How important is this sensor to the ECU? Help!

 

What exactly did you do the "break" the airflow meter???
What exactly is broken?&nbsp Plug?

Actually the receptacle to the plug. Plug is ok. Gonna go junkyard diving today if I can squeeze it in. I just can't get the car to start now, and I need to know if it is the sensor or if I messed something else up...

 

You'll need the airflow meter functioning.&nbsp By the way you describe the start-up, the AFM is either disconnected or not functioning properly.

So the car should not run without this sensor then? That makes me feel better. Now off to the junkyard like lightning!

Thanks,
James

 

No, it'll crank, catch, then die.&nbsp What's actually happening is there's a fuel-cut switch inside the AFM itself, so it's cutting the fuel before the engine starts up.&nbsp If the plug is disconnected, the stock ECU freaks up and cuts power also at the same time.&nbsp Good luck finding a replacement!

Caught my error in terminology just before your reply.

Thanks again,
