Code P0134
I know it’s coming up as O2 sensor but all was fine until 3 things. Radiator split, changed air filter (for stock replacing dirty) and filled up with Tesco momentum.
Im wondering if either the car doesn’t like momentum (added a octain booster to see if it help and it hasn’t)
Changing the air filter I Knocked the wiring perhaps
or it’s compete chance and the O2 has failed.
It’s a jdm 2005 hawk that I’ve had no issues with until the above.
cleared the code but it returns.
should I fill with v power, change fuel filter and see what happens or is it only going to be a failed sensor.
do I really need to take the wheel inner plastics out?

DTC P0134 O2 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR 1)
This refers to the A/F sensor and maybe just a blown fuse, damaged wiring or dead sensor.
As it's a twinscroll, AFAIK, the A/F sensor is in the top of the down pipe after the turbo with the O2 sensor just before the donut joint.
So no need to go looking in the offside wheel well for the access flap to the manifold as with the single scroll turbo models.
Part number for Rev E or F model 22641AA191
ICP price £295 inc VAT

I assume the fuse is inside the sensor? I’m hoping that messing with the air box agetated the loom or something.
it has an aftermarket alarm with a large black pressure switch behind the air box.
is the o2 easy to see from the engine bay?

The A/F sensor will be on the inboard side of the down pipe as shown top right of this picture (black cable)
Probably need to remove intercooler to get to it.

Rob, I had this issue with my JDM, same code. Although every case is different it was the sensor that was faulty and needed replacing.
Indeed you do need to remove the intercooler to change the sensor. Just make sure you buy the genuine sensor not a cheap copy such as a Denso etc. I’m reliably informed it must be the real deal.

I could be wrong with the brand in that case but I was specifically advised to buy the genuine article when mine when wrong by my tuner and that seems very apparent when searching the forum for similar instances. If Denso was the proper thing then Denso it is, just get the genuine article.

I’m suprised no one since 2005 has found a uk alternative (maybe they did) but according to Denso the following will work:
Hi Rob,
According to our e-catalogue the DOX-0306 Aftermarket part number would be the right fit for your car.
Where in the UK are you located so I can look up the closest DENSO distributor in your area.
Kind regards

DENSO Aftermarket Europe
The question is... who’s brave enough to try it.
Weirdly I checked my fuses and made no change. Touched all the wires and it made no change. Went to the local shop and the light didn’t come on!. Went for a blast and it still didn’t come on..
maybe it’s fixed?
