I have a p28 ecu and it throws this code out does anybody know how to correct this problem thanks

 

i think the best way would be to just replace the o2 sensor with a new one........check ebay for a denso o2 sensor.....should only be about 45.00 or so

 

Are you using a 1 wire o2 sensor or a badly wired 4 wire by any chance?

 

3 or 4 wires

 

Well, hope it's four because there is no three wire o2. Just the wiring and stuff and if that's fine (if it was stock and not wired in a CX or VX) get a new o2.

 

Had the same problem. Thats the o2 heater. Before you replace the o2, check to make sure it is getting the right voltage, or it wont work. If youve got a bad connection, run the heater wire to the positive on the map or tps sensor. That would be a quick fix.

 

thanks guys
