I installed the Bullitt CAI and tuned with a 93 Octane tune from Brenspeed on my '09 GT. The check engine came on and the DTC code reads:

p0053
p0054 heater resistance h02's.

Is it OK to drive it until Monday? It seems to be running fine. I just won't take any chances with my pony.


Thanks in advance for your input.

just being the heater circuit it'll be fine. The o2's have a heater element inside to help warm up quicker to cut down polutants. it's fine

So, could you explain why it is throwing this code? Does it have anything to do with the tune? Or could it possibly be a bad sensor?

Thanks

i don't think it's the sensors. The pcm as a return signal coming from the sensor to monitor the circuit. if it doesn't see it the code(s) get set. if you got both those codes I believe they are for the first and second sensor for bank 1.I would have to see the wiring diagram to help you out better right now but I can't at the moment. It may be the tune also. Try reflashing it to the stock tune and seeing if it comes on again so we'll no if it's possibly the wiring.

I installed the original stock intake and reflashed the car to the stock tune. Guess what? No CEL ! At this point, I am thinking that it must be the Tune. Do you think I might try to install the Bullitt intake and reflash with the Brenspeed tune in the AM when the engine is cold?

Thanks

being cold shouldn't matter. The program might have a hickup for that pid or something. Call up Brenspeed and see what they can do. A+ service so they should be able to correct it no problem. I too think it's the tune so see what they say.

I will let you know what Brenspeed says when I call them on Monday.

Thanks again for your help
