I checked and do have 12 volts at the plug. Not sure if I have a good ground or not. I wish I knew which wire going into the ECM was the wire coming from the heater so I could check for a broken wire.
Toyota sensor (so yes, denso). I have not cleaned the MAF, I had found that suggestion somewhere but have not done it yet, I did pull it one day and it actually appeared very clean, that is next on the list though.
Just as the title states, 2003 V8 4runner, replaced a/f sensor because of a p0031 for and how get a p0032 that won't go away (comes back instantly if it is cleared).
I used a A/F direct from Toyota
Thanks for any advice.
I used a sensor direct from Toyota as well. I have tried to figure out what actuates the heater circuit thinking maybe a relay was stuck or something causing the heater to stay on all the time.
I am having issues with an a/f sensor. It was a p0031, I replaced the sensor and instantly got p0032, can't figure out what the deal is with it. Runs great otherwise.
Mine does this, I hate the thought of how much fun it would be to change the blend door... Luckily it's my wife that drives it daily so I don't have to listen to it often.
It had about 197k on it when I bought it, I have replaced the rear pads/rotors and it needs front pads I think. Also replaced the tires. I miss the minivan (which we actually still have) but my wife wanted another 4runner, we used to have a 1998. I do love the fact the 4runner has a hitch and...
I just bought a 2003 w/ v8 that has a few minor issues, but the only one I need to fix is an o2 sensor (A/f actually). It was a p0031, I replaced the sensor and instantly got p0032 that won't go away (31 went away). Now I'm at a loss of what to do next.
