Thread: Replacement airflow sensor

PhilipA by de energised do you mean battery disconnected?

I didnt realise disconnecting the maf induced limp home mode. I was told that the maf can be disconnected for a short period but fuel consumption would be up.

It ran the best like this since the misfiring started. I will replace the maf anyway to be on the safe side. Just need to work out why I still have this damn misfire.

And D1s do NOT have O2 sensors, so a bit problematic looking for O2 sensor output.

Very true.
I guess you can prove a dead one but not a good one.

Generally if a vehicle has no O2 sensor I use a wide-band sensor with controller and still log against TPS and MAF.
