David Clarke Posted December 25, 2019 Share Posted December 25, 2019 I have just bought a Subaru Impreza wrx sti 330s and all was well until the engine light came on along with the cruise control and sport mode flashing and the traction control being turned off, I plugged in a diagnostic kit and found that the O2 sensor had an issue (bank 1 sensor 1) so I replaced the sensor for a new one and deleted the fault code, how ever the same fault is still showing up, anyone have a clue of anything else it can be?

stuartie Posted December 25, 2019 Share Posted December 25, 2019 What other info did you get with the o2 fault e.g open circuit or short to ground etc as it could be wiring also was it a genuine sensor or a copy part coz a few folk on here have had trouble with non oe sensors 👍 1 Quote Link to comment Share on other sites More sharing options...
David Clarke Posted December 25, 2019 Author Share Posted December 25, 2019 The only information I got was “control circuit low” and I got the sensor from euro car parts and it was a universal sensor, I had to use the plug from the original sensor but I proved that I was getting continuity from the plug to the actually sensor in all wires so I just put it down to the sensor not working as it should so I replaced it but now I’m thinking it might have something to do with the wiring of the car and not the sensor?

stuartie Posted December 25, 2019 Share Posted December 25, 2019 You will get continuity down wires even if they are just hanging by a thread, you will be better off testing the resistance down the wires and if any of them show a high resistance thats what the fault could be but i would also see about getting an oe sensor and trying that bud 👍 Quote Link to comment Share on other sites More sharing options...

Mr B Posted December 26, 2019 Share Posted December 26, 2019 Guess that was a heater control circuit low ? exact codes/details enables far better answers . euro car parts about last people ever want use if want quality parts or real value . They a bit like sports direct buying known brand names and sticking those brands on very poor quality parts and retail it at twice real price then discount code it make consumers think it sale of the decade when in reality it overpriced tat The OEM sensors are denso and denso is all we use as less problems out the packet and lasts properly . You can test heater circuit with incandescent bulb . you want test heater element resistance in old and new sensor too . 1 Quote Link to comment Share on other sites More sharing options...
