SOURCE: need to replace bank 2 sensor 2 on 2003 toyota

Bank 2, sensor 2 is a heated O2 sensor located below (after) the catalytic converter on the passenger-side. When this sensor gets clogged and/or goes bad from rust and heat fatigue, the voltage drops low enough to cause the electronic control module to register error code P0161, which then causes the check engine light to come on.

To replace Bank 2, sensor 2, remove the debri shield from just behind the front bumper, underneath the vehicle. There will be 10 bolts holding it on (10mm, I believe). After removing it, look toward the center of the newly exposed area and you will see 2 finger-like objects projecting out from the engine with wires coming out of each. The one on the left (passenger-side) is bank 2, sensor 2. The one on the right (driver-side) is bank 1, sensor 2.

I got my direct-fit sensor online for $55 from Remart Auto Parts. I know it is tempting to get the universal-fit type and save the cash. But after doing that once, I wouldn't care to do it again.

I found a YouTube video showing pictures of where the two lower (after catalytic converter) sensors are located. While the video only points out the driver-side sensor (bank 1, sensor 2), it's easy to spot the other one being only inches away.

SOURCE: check engine light on 2003 toyota tacoma, O2 sensor?

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.

P0135 code


The heater element in the sensor has failed. Very high chance that replacing the O2 sensor will fix this issue.

Rare, but the engine computer may not be sending a signal to heat the sensor or a wire can be damaged. but this is very rare. Try replacing the sensor first. Its very simple.

this code is showing you the computer knows the circuit is not complete for some reason.

What is code p1055 2003 Toyota Highlander base model


The code 1055 is brand specific, and for Toyota it means there is a problem with the heater circuit for the O2 sensor bank 2 sensor 1. That is the sensor in front of the catalytic converter or split and on the side with cylinder number 2 which may be the passenger side.
The sensor could have failed, or it could be a problem with the power source for the heater inside the sensor.

Engine code 430 for 2001 toyota highlander


Possible Causes:
Oxygen (O2) sensor not working correctly
Damaged or leaking exhuast (pipe, manifold, catalytic converter)
Damaged catalytic converter

Diagnostic Help:
To diagnose a P0430 trouble code we begin by checking for exhaust leaks under the vehicle. Then use an oscilloscope to check the waveforms of both upstream and downstream O2 sensors. The rear reading should vary, the front should be steady. Replace as necessary. Check the rear Heated O2 Sensor. Check the catalytic converter, replace if necessary. If necessary, check for wiring and component. hopes this helps thanks

Check engine code P1135 Toyota Highlander v-6


what you looking at on that code is an o2 sensor, the 1135 is bank 1 sensor 1, that says which o2 sensor it is, since most vehicals, especially new foreigns have more than one, this code refers to the first one in your system so if you follow your exhaust manifold back to your pipes, the first one you see, probally right on the manifold, is the one thats malfunctioning. To change it, simply disconect the plug, and use a o2 sensor socket with a ratchet to remove it, and screw the new one back in and plug it in. Pretty simple, wish you luck.....
