Hi all,

I put a decat up pipe on my bug wrx and couldn't get the probe out of my standard up pipe so just left it out. I assume its a egt probe?

Anyway car worked fine without it for a few days then yesterday the management light came on.

Does the ecu only check the probe under certain conditions? I was about 10-15 mins into my journey when it came on.

I've since plugged the laptop in ans switched it off so won't happen again but was curious as to why I didn't get a fault straight away?

Thanks

 

it is an egt sensor, you can fit a 2ohm resistor a d this will fool the ecu and switch the light off. You need to do it on the car side rather than the sensor side, and it will take a few days of driving before it switches off

 

Cheers its ok I have swiitched off the section kn the ecu that looks for it already am happy to leave it out just curious to why it took a few days to throw up an error

 

Yeah as Iain said, i have just had to do the same to mine.

Scroll down to the CEL fix section.

 

I think the ecu needs to take a number of readings before it recognises that it's different and throwing up a potential error

 

Yeah mine didn't go off immediately , it only took a mile or so though.

 

Someone with a tactrix cable could disable the error for you,I used my cable to do mine.

 

It would just return though ??

 

Just out of interest - what is the fault code for that?

I'm going to change my uppipe soon, and delete the sensor.

 

No you can turn the dtc off completely so it wont trigger the CEL (if you have ecutek though it will need to be done by them)

 

Oh I didn't Know that

 

Yea I have turned the sensor off did it soon as I got home

I can't remebr the code sorry.
