Hi all.
Im hope someone in here can help. i have a Seat ibiza 1.2 6n 3 cyl where the engine lamp has turn on. reading the ECU give me code P0135 O2 Sensor Heater Circuit malfunction b1 s1.
i replace the o2 sensor with a new one, and reset the ECU but the error turn on after driving 10 min, the fuse seem to be ok.
the wire to the o2 sensor seems fine. my question is
1. its a 5 wire o2 sensor. red,white,gray,black, yellow, what goes for the heater + and - ?
2. it there a switch relay there control the heater circuit. can't find 12 volt on any wire. to the o2 sensor ?
