I'm in the process of replacing my exhaust & cat pipe & have purchased a new O2 sensor form SJS, I'm sure I read somewhere but can't find it now that when replacing the sensor you need to reset the ecu, can anyone confirm this & if required is it best to disconnect the battery or reset if using Freescan ?

Many thanks, Phil

I'm not aware that you need to reset the ECU but to do that, disconnect the battery for a few seconds. You can't reset the ECU via Freescan.

hello phil have you had the error code crop up again?

Hi Peter,

I've just replied on the original thread in Freescan / Ecu forum.

So far so good, been out three times now & no faults or CEL.

Original sensor now gone back to SJS so just awaiting response form them before ordering a replacment.

Regards, Phil.

P.S. looks like you've been busy. Boot floor project looking good :-)
