I'm still getting these codes. I have cleared the codes with OBD2 scanners, and ecu reset. I'm wondering if putting in new sensors will fix it, or will it just come back on. I have test pipes with the non foulers, so is this not working anymore, or will the new sensors fix the problem? I know there is really only one way to find out, but I just wanted some opinions. Also these codes came up after my Vortech install with a bad tune. The tune has been fixed and the car runs great, but I still have the SES codes. Could the bad tune possibly damage the sensors?


P1167 heated O2 sensor 2
P1271 Air/Fuel Ratio Sensor 1
P1273 Air/Fuel Ratio Sensor 1
P1281 Whatever that is

 

If it was tuned very rich and driven like that for a number of miles, yes, it can damage the sensors.

Was it rich?

 

Yes it was very rich. Thank you for your response. This confirms what I was thinking. Time to buy new sensors.

 

So which sensor is which

P1167 heated O2 sensor 2. (below the cat driver or passenger side)
P1271 Air/Fuel Ratio Sensor 1. (above the cat driver or passenger side)
P1273 Air/Fuel Ratio Sensor 1

 

Time for a re-tune as well.

 

Jeremy at PF fixed my tune, and now the car runs like a champ. I just need to replace the sensors. I will need to find out what side needs to be replaced.

 

Can anyone recommend a good place to buy O2 sensors. My dealer wants 180 each. I'm not looking to splice any wires either.

 

I think I finally figured out what the problem was. I replaced the O2 sensor fuse and reset the ECU. So far no more SES. I should have thought of this over a month ago.

 

Good to hear!!
