Hi there I just purchased a denso lambda sensor for my 2003 wrx I had to attach the plug from my old sensor so I attached 2 black blue to blue and white to white assuming this was correct but I'm having the same fault come up prob with heater I assumed this would fix the probl I'm stuck to what to do now

 

denso sensors come with the lead, are you sure it`s the correct one ?

 

From what iv read u can get one with the connector or without but the ads didn't mention anything about it no having one so the wires from the harness are different from the sensor

 

have you got a link to the sensor for sale ?

 

It's one on ebay for my car don't have a link its a faulty heater for the sensor

 

SUBARU IMPREZA 2.0 WRX Turbo AWD 2000.12-> EJ205 160kW LAMBDA OXYGEN SENSOR This was the add on ebay which I believe is mine I have a 2003 wrx

 

I dont think you have a Denso sensor at all fella, I think its a cheap copy.

 

DOX-0113 Is the part no in a genuine box with denso stamped on the sensor

 

How do I check the wiring harness for problems relating to the heater fault on the sensor
