I have a 2005 Wrx and bought a new O2 sensor which appears to be Denso. Has the markings and the packaging however it’s throwing the code P1130 air fuel ration circuit open( bank 1 sensor 1) this Was sent as a replacement for the first which I thought was faulty as that was doing the same. The one I took off only came on after a track day so thought I’d replace it. The new ones are worse than what I had. Is there a possibility it’s a fake Denso or do I have an issue?
I bought the sensor from Parts4youuk on eBay. They say the sensor is real. I don’t know if they cleaned and sent me the original one back.
The MY05 workshop manual doesn't list a P1130 DTC but does have a P0130 which equates to open circuit.
Subaru part number for the front A/F sensor is 22641AA042 Denso equivalent DOX-0306 https://www.importcarparts.co.uk/par...y=&searchPart=

Don that fuse sbf-5 would give him an open circuit would it not. It doesn't necessarily have to be the sensor.
