Engine: 2.3 F/Inj B23E/B230F: - Lambda light on.

Hi
My 240 GLT has the Lambda light on. This happened after the car the front tyres were changed. The car was jacked up on a trolley jack and I was wondering if this may have damaged the sensor in some way.
I checked the fault codes and initially got a 1-2-1 faulty signal from air mass meter. I cleared the codes and this did not reappear, now giving 1-1-1. The car appears to be running fine.
I profess to being mystified by the workings of injection systems and how the lambda sensor interacts with engine running.
All advice welcome.

I've also been having issues with my lambda light, it has come on twice now both times showing the same 1-2-1 fault. Each time the car spluttered a little for about 10 seconds as if there was a fuelling issue (dirt in the injectors maybe). First time I took it into my local garage as I needed the exhaust changing anyway and I thought that this was probably not helping. The mechanic found nothing wrong so reset the light and all was well until it happened again.

The second time I went after the fault myself and using the Haynes manual and a multimeter checked all the MAF readings, and sure enough the resistance was spot on and the little voltage surge occured just as I turned the engine off. The car drives fine and if anything my mpg seems slightly better so I am currently ignoring the light.

Just one question - how do you reset the light, I have followed the procedure in the manual and the light stays on, or does this mean that there is some other fault?

My car is a 1992 SE with a B230F engine

Thanks

Try disconnecting battery for ten minutes (make sure you have radio code). This always works.

There can be up to 3 codes stored, I think, in each of the two sockets.
