So I put an frankencar intake in my 02 and I've gone about 400 miles. Everything is fine, but then my SES light came on. So I pulled the code: P0037 - Heated Oxygen Sensor 2 Heater Low Voltage (Bank 1). I figured it was the MAF but amazingly its an O2 sensor. Does this mean my sensor is bad and I should replace it? I reset the ECU, should I give it some time and see if it comes back on? Thanks

Ok, the light came on again. I guess I'll go ahead and replace that sensor. Where's the cheapest place to pick one up? Thanks

how did you reset the ECU? unplug the battery?

 

Clean the maf?

 

reset with the whole pedal, key turn scenario etc.

Havent tried cleaning the MAF, to scared it'll break. How do you clean it? And why would the MAF throw a 02 sensor code? thanks

shaz,
cleaning the MAF is easy. I did it last night. I used a little isoprohply alcohol and a q-tip and as you know be careful.

I tried messing around with the pedal, key turn stuff last night but I didn't have an analog clock, I just kept counting "Misissippi"s. =] I need to find me a good analog clock so that I can try this for real.

 

One thing I neglected to mention, once you unplug the MAF and remove the two tourque screws, it is a pain in the **** to get out. I had to use a screw driver to "gently" pry it up from both sides. It helps if once the screws are out, you turn it 90 degrees so that it is perpandicular to the screw holes. I hope that makes sense.

 

Its a pain to get right... even with a stop watch it took me like 8 tries. I cant figure out what the trick is to get it every time. Anyways, maybe I'll try cleaning it. thanks for the suggestion

 

yeah it sounds like a major pain but it works and that's fantastic! this is the first confirmation i have of this technique actually working.
