You can go to autozone.com and register for full free online repair manual,
Register, login, choose year, make, model, engine size, and view repair manual.

It has diagrams, testing, component locations, replacing, parts, product info, and much more.

The sensor is on the bottom half of exhaust manifold usually. Heat up exhaust or heat with torch, then use an 02 socket and breaker bar to pry loose.

What is the P0420 code on my 2004 toyota tundra


the P0420 CODE IS INSUFFICIENT CATALYTIC FLOW , FIRST CHECK OTHER SENSORS BEFORE REPLACING THE CATALYTIC CONVERTOR, CHECK YOU REAR OXYGEN SENSOR TO MAKE SURE IT IS WORKING FINE, THEN CHECK YOUR EGR VALVE, MAKE SURE IT IS NOT LEAKING, CHECK YOU MASS AIR FLOW METER IF IT HAS ONE OR AIR FUEL RATIO SENSOR, THIS WILL BE THE TOP OXYGEN SENSOR. IF ALL GOOD THE CAT IS THE PROBLEM, THAT IS THE TOP CAT.

2001 Toyota Sequoia Oxygen sensors


No the wires won't likely be the same length

The front upstream sensors, are not the same
Part # as the rear,downstream monitor sensors

Go to Rock Auto.Com & look up your oxygen sensors
I would get the NTK or Bosch,if they have that

You do not replace the rear sensors, until they fail

You replace the front ones at 100,000 miles or sooner,
if they fail

2002 toyota le 29,780 Miles check light on during driving code p1135


Code p1135 is a code for an Air/Fuel sensor (oxygen sensor). Bank 1 sensor 1. IT comes up when their is a problem with air/fuel mixture in the engine. It would be anything from a blocked air cleaner, faulty or fouled spark plugs to a blocked exhaust pipe/catalytic convertor. I would get these checked out, and if they are all fine the sensor its self or sensor circuit may have failed, requireing replacement. With your low miles, hopefully this maybe covered under warranty if it is the sensor.

Where is bank 1 sensor 2 oxygen sensor located?


The bank 1 sensor 2 sensors are always oxygen sensor located behind the cat converters, the A/F ratio sensors are always in front of the cat in the exhaust manifold, the part number for the sensor B1/S2 is 89465-09290 from Toyota. Thanks.Helpmech.

I have a 2003 tacoma pick up truck and the check engine light went on. I took it to my mechanic and he said the p0420 code came up and it was a catalytic converter. I only have 38,000 miles on it so he...


Well, the P0420 means "Catalyst System Efficiency Below Threshold (Bank 1)" - that both oxygen sensors (the one before the converter and the one after the converter) are reading about the same, meaning the converter is not working within the set efficiency envelope.

the "Bank 1" is just a way to differentiate between right and left for dual exhaust and dual catalytic converters - Bank 1 or Bank 2

Then they have (Bank 1 Sensor 1) (Bank 1 Sensor 2) (Bank 2 Sensor 1) (Bank 2 Sensor 2)

In any event, it sounds like Toyota was correct, but, WOW , A few hundred? Considering the Oxygen Sensors cost between $124 and $194 (front or rear) - you can safely say the part will cost $200 - even at the local parts house. Then the shop labor - which will NOT take more than 20 mins to replace since they nailed which one needs replacing. Unless its a ****** doing it. They have shop minimums though I'm sure.

Good Luck and Take Care

Welcome to FixYa. I'll be glad to help you out.

Code P-1150 indicates an Air-Fuel sensor range/performance issue.

The air fuel sensor is similar to an oxygen sensor, but it does a different job.

Without in-depth analysis on a scan tool that can read the output of the A/F sensor, it is hard to tell you exactly what is happening, but prior experience indicates that you probably need to replace the A/F sensor.

You would do well to purchase a genuine Toyota A/F sensor, as the cheaper 'aftermarket' units do not perform well; your check engine light may remain on after you replace the sensor with an aftermarket

Thanks for choosing FixYa for advice.

I took my 2002 Toyota Highlander to autozone because the check engine light was on. They told me it was code P1150 - manufacturer air/fuel metering. Is this an oxygen sensor? My Toyota is a 2WD 4 cylinder....

Replacing and oxygen sensor


1989 has one oxygen sensor. 1996 and up have two, three, or four. Depends on which engine and exhaust system you have.
