OXYGEN O2 SENSOR burned out

Why wait untill the thing craps out completely.... if its not right, get it fixed *NOW*, don't wait.... it will be a lot less expensive in the long run.

I had the same problem with my truck. I fixed the converter and saved the sensor for a while.

The sensor is around $200. You can tell if the sensor is broken by going under the hood. Using a jumper wire (per maint. manual) to test the blinking light when you turn the key to accessory. Depending on the flashing light sequence, It will give you an indication that the sensor is a likely faulty. However, you must test the other sensors for that light sequnce to be sure. I happen to find a brand new OEM sensor on eBay for $50. My lucky day.

The oxygen sensor is replaced for free in the USA only when the vehicle reaches it's first 80 000 miles regardless of the age & number of owners as stated in the factory owner's manual in the maintenance section,some Toyota dealerships are reluctant to replace it for free if that happens contact the Toyota regional head office for your region where they will give your local dealership 48 hours to comply. On average the oxygen sensors should be replaced every 6 years or 100

000 miles or so which ever comes first as stated in the owner's manual,warranty booklet and factory service manual.

If it is not under warranty then from my/others experience/research purchase an o2 sensor in the following order:

1)Toyota (NipponDenso now called Denso) 2)Denso aftermarket (Same as original but sold aftermarket) 3)NTK (oxygen sensor division of NGK)

Available at:

(10% shipping by Fed Ex orfree shipping with $100 & over speak to Roger at 1-888-271-3948 before you replace the oxygen sensor soak the 14 mm brass nuts with any of these deep penetrating oils several times for several hours:

1)PB Blaster 2)Liquid Wrench 3)Kroil Oil 4)Aero Kroil & Sili Kroil 5)Toyota Rust Penetrant or High Performance Penetrating lube 6)Rust Check

the first ones being the best,also if you decide you need new ones here is the Toyota part for the exhaust manifold (brass)nuts # 90179-10175 (14 mm socket)

Have you tried to get Toyota Canada to replace it? What did they say?

It's not listed in the Canadian owner's manuals so they won't replace it for free,I called them 6 years ago.
