Check Engine Light
The CEL on my '99 4Runner 3.4 L 5 speed came on the other day. I read the codes with my OBD II reader. They are: P0125, P1135, P1133,P1135. I couldn't find a listing of these to describe what they mean. I was hoping that someone on here could help.
Thanks in advance.
Dave

Thanks for the code lists, guys. I think it needs a new O2 sensor, but am unsure of which one. Also, I don't understand why it would be giving a coolant temp sensor and pedal position sensor code.
Thanks,
Dave

Thanks for the link for new O2 sensors. That's the best price that I've seen. Has anyone else got the same code when the O2 sensor goes out? I'm sort of confused as to why the other codes are showing up. ' Just wanted to make sure something else isn't wrong with it.
Thanks,
Dave

Word of advice:
If your car must meet California Emissions standards, the O2 Sensor is called the "Air-Fuel Ratio Sensor" (or simply A/F Sensor).
I made the mistake of replacing mine with an Autozone O2 sensor, but still failed the Smog test. I went and bought the A/F Sensor from a Toyota dealer (the only place where you will find that piece) and it passed Smog with no problems.

I live in WV, so I guess the replacement Denso O2 sensor should work fine. I might do both of them since they're $79 each. Can these sensors be tested by using an DMM with the car running? I wasn't sure if the harness could be unplugged and a meter used to check for fluctuating voltage readings.
Thanks,
Dave
