i have my02 wrx, have been running decat pipe from turbo back with CEL fix on rear O2 sensor, been like this for 6 months, now have fitted stainless uppipe to turbo, since fitting i am getting only whilst steady driving on light throttle at 70mph CEL coming on with fault code of:
p0546 exhaust gas recirculation temperature EGRT sensor bank 1 signal too high,
i obviously need another CEL fix for the sensor in the up pipe, any one know where i can get one from or even better what the resistor values are for the fix.

 

1/2W 2.2ohm will do it, 7p from maplins as i found out on saturday

 

cheers matey do i need two of them like in the rear 02 sensor fix i installed

 

i only used one to fix my egt sensor in the downpipe......try one, if thats not enough, then use 2

 

what year is yours, can you remember which wire it was you went to, what colour, little puzzled you say in your down pipe, mine is in the turbo link up upipe.

 

mines an 03, there are sensors all over the place, there is one in the up pipe too, but the one i replaced was the first one after the turbo cos it was giving duff readings...

 

right i got air fuel ratio 4 wire sensor in exhaust manifold on turbo side of car, then in the up pipe i have a temperature sensor two wires, then in my exhaust after the rear cat there is an o2 sensor, the afr sensor has a black protective shroud and the o2 sensor has a bright yellow one, is that the same as yours, i need a fix for the temperature sensor for when replacing the cat up pipe with stainless non cat pipe,

 

i cant check mate, the cars not with me during the week, im sure someone will know though....

 

Do a search under cell fix you will find I have posted a few times on how to do this mod.It is the two wires with the black shrouding at the top of your uppipe by the way.

 

yep know exactly which sensor it is, as it keeps frigging working loose aswell, i know i am not on my own there discovered a few of you also had this happen,
called in maplins today on way home from work, got meself a 0.6w 2.2kohm resistor, popped it connector block as per way shown on some other thread on forum (thanks who ever it may have been) cleared the CEL light with my laptop software, drove the car in the same manner as to make the light come on, it never he he at last, all i need to do now is pop out the EGT sensor, and bung it up, cheers to you all, the problem now resolved, oh by the way one of the subaru tuning companies wanted 45 quid for the cel fix resistor, cant believe that for a 7 pence jobby,some proffit margin.
thanks again
