The OP was from a few years back, so he probably have correct his problem. P0125 doesn't really have anything to do with the waterpump, needs a bank 1 sensor 1 Oxygen sensor maybe.

N.E.O.

As NEO posts, this code is often misleading.

So are you guys saying that I should disregard the dealer's recommendation of replacing the drive belt and the water pump to clear the check engine light?

OK! Just for reference, this is for a Camry, on page 61: http://www.camrystuff.com/manuals/Gen4/Diagnostics.pdf. Do you see any mention of the water pump for possible cause? Corolla is pretty much the same for the causes.

N.E.O.

Do you know where i can find the part number for the O2 sensore for a 99 corolla?

Check the sites vendor section for possible source of parts. A lot of members also use RockAuto.com for parts source too. Stick with Denso though if you go aftermarket.
