Don't mean to bring this thread back from the dead but I have a MY01 with a megan header and test pipe with defoulers on both the primary and secondary and throw codes with in 50 miles of a reset. i was planning on going up to O'reilly's or Vatozone and getting the codes read. I think i may need to take the de foulers off the primary, but i'll see when the codes get read.

can anyone help me with the codes relevant for this mod? so far i have
p 132 - primary o2 sensor high volt

and then theres one for secondary and another for cat efficiency out of spec. is there a code for both primary and secondary high voltage and low voltage? i have the service manual but i haven't found codes in it yet.

 

leave the primary ALONE your car wont run right

primary ALONE

secondary double stacked MY00 here no issed for 4-5k miles

 

i took the defouler off the primary and double stacked the secondary, solved the exhaust code. now just fix the p411 (secondary air injector or something? says flow detected up stream?) code in the intake and she'll be good. thanks speed junky

 

do a quick search on here for that code you will find the solution quickly

 

For people from the UK looking you can buy one from Tegiwa

I haven't tried this but it may work.

is resetting the ecu necessary ? wouldn't it go off after 100 miles or so?

 

the CEL will turn off after a couple of cycles but the code is still there untill you reset it.

 

So if I didn't reset the ecu, is it still going to pull timing even after the cel went off? IIRC, when cel comes on with the code directed to the censor on the cat wil make ecu pull timing?

 

your. ecu will still be thrown off air fuel ratio will be off and car will run lean untill you clear the code

 

Hahh it's air/fuel. Sorry I don't know what the hell I was talking about -.- Definitely resetting it tonight! Thanks man! Very much appreciated
