    My check engine light has come on in my 04 D-cab 3.4L PreRunner, and I took it over to an auto parts store for them to read the codes for me. This is what it said:

    P0031
    H025
    Bank 1 Sen 1
    Heater Circuit Low

    Can someone interpret these for me. What exactly are these codes, and what is the fix???

    Thanks,

    Jason

    Replace the passenger side O2 sensor. The one before the cat.

    After I do this, will I need to reset the check engine light, and if so, how do I go about doing that? How much is this sensor going to run me?

    I called AutoZone today and got a price of $179 for the bank 1 sen 1 O2 sensor. Where is the best place to get this sensor? Does that price sound high? Ouch.

    Been many years...but I used to order all my parts from this place. It's a Toyota dealer.

    http://www.partznet.com/index.htm

    Tell 'em your a member of TTORA (Tacoma Territory Offroaders Association).
    Their internet prices are pretty damn cheap compared to calling up your local dealership.

    I think my 02 sensor (years ago) was like $80 shipped.
