Guy's,
I have a decatted my00, with a dawes and filter, the CEL has not come on for at least 6 months, but, I just took a leisurely drive to town, and it came on twice, an even gentler few miles and it goes out. So, any ideas??

Also, which plugs do I put together under the dash to get the error code tp show??

Ta in advance.

Ron.

 

have a look here

Sounds like a sensor going out of range and then back in when you drive it slowly.. MAF or Lambda at a guess..

Take it easy until sorted.

TA,
Do I need to connect both pairs of connectors to do just the diagnostic test then??

 

Yes..

Connect them both, turn immobiliser off, turn on ignition (don;t start engine yet), place foot to the floor on accelerator, back to half throttle and hold for a bit (I do 30seconds), foot off accelerator, start engine and drive.. just drive it slowly..
you will get a flash on the CEL after a couple of minutes or less.. either the ok code, or an error code. Disconnect plugs.

Ron,

Glen had this and it was the 02 sensor.

Hi Ron

JGM just described how to reset ecu

To get the error codes just connect the two black connectors, switch the ignition on, immobolizer off etc the cel light will flash like morse code this is the error code

if your around poole if you bring it over i'll tell you

Very true.. sorry bit tired when I wrote that..

error codes are just one of the connectors, I think it is black ones.. says on that website..

Am sorry I must have miss ready your replace RON.

Thanks guy's, I'll try to get round to it tomorrow.

 

Just in case it is the O2 sensor, where is it, and, can I change it myself??

Ta.

 

Sensor is situated at the top of the downpipe, just by the turbo

Shouldn't be too hard to do, I'll let you know at the end of the week as my replacement should be here by then!

Mike

 

Mike,
I always thought that one was the lambda???

 

They are different names for the same thing

 

Thanks,
I've just done the check, it flashes loads, it tells me code 11, (crank sensor) 12, (starter switch) 32 (O2 sensor) and 53, (fuel pump or circuit)
So, it would seem to me, that the fact that the car rub=ns fine, could just mean that the )2 sensor need changing, as, if all the others were wrong, it wouldn't run, would it?

As you can tell, this is all pretty new to me, I could strip and rebuild a Mini in my sleep, but not a Scooby!!

Ron.

 

reset the ecu so the codes clear and see if it reoccurs and what code you get then

 

Too dark now, will do it tomorrow.
Ta!

 

just roughly, how much would a new O2 sensor cost??

 

Bought mine from a company on the web.

I think there site is down at the mo. Will post url when its working again

Depending on how many wires yours has it'll cost between £25 and £35ish

Mike

 

Cheers mate!

 

Website is back on now!

O2 Sensors

Mike

 

RON, find someone with a SECS monitor... That'll tell ya exactly which codes are appearing. (I never could count the flashes properly!).

Their website has tech info downloads in the top right hand link, giving full details of the error codes and their meaning.

Wonder who did their website?

Squizz.

 

Just done a reset, shows no errors, so til next time, it's ok!!

Cheers for all advise!

Ta
Ron.

 

Jolly good.. just keep an eye on it.. now you know how to check for codes you can check for them once in a while.
