I think my Lambda sensor could be on the way out !

Can I check the Lambda readings through the PowerFC and if so,what should they be ?

if u can, they should jump from 0 to 0.75 Volts or so whilst idling...mine died the other day and it was just sitting at a lazy 0.2- 0.3 Volts

ETC --> SW/Sensor Check --> O2... as said the voltage should be rolling around etc.. would be worth mounting the new one in your downpipe as they fail fairly often in the headers.

Checked the lambda readings through the PowerFC earlier,idling is sat at 0.02 volts sometimes goes to 0.04-0.08. Sat on the motorway at about 60-70mph it's showing around 0.40-0.50 volts.

Pretty sure it's knackered,am I right ?

Yeh it was,i've turned it off at the moment until I fit a new sensor. I have a spare one so hopefully i'll fit it tomorrow.

Am I right in thinking you mentioned something about the lambda maybe playing up when you came back to check the car over ?

Fitted new sensor and everything seems good now

At idle the voltage goes up and down from about 0.02-0.75 volts.

No,just fitted it in the original place for the moment. Didn't have time to fit it in the downpipe
