An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

What does toyota codes PO037 and PO136 mean?

P0037 is "Heater Control Circuit Low Bank 1 Sensor 2".
P0138 is "Oxygen Sensor High Voltage".

It sounds like it's time to check the connector to your oxygen sensor, and probably replace it (the O2 sensor).

I got a p0141 code on my 2001 tacoma v6 what is the problem

p0141 indicates that the heater in the upstream (#1) oxygen sensor has failed. It will take longer for the O2 sensor to heat up, taking longer for the computer to go into closed loop, which burns more fuel. Replacing this sensor is pretty easy, I believe it involves removing one plug and two bolts. After it's replaced, any auto parts store with a code reader can turn the check engine light off, for free.

Toyota tacoma 2003 check engine light is

If the car still runs then the problem is not major but may develop into one if unchecked. The sensors in the engine may have detected problems and should be stored in its ECU. If you have a scanner have it connected to the diagnostics it should give you a clue on what to check out.

Check engine light won't stay off

you could have a short in your o2 sensor wire and there for its not reading.Get a shop to hook up a diagnotic scanner and read what they are doing so you can see if its a loss of comunication or not and then go from there.Also make sure it was factory replacement o2 sensors and not one of those multifit jobs.
