What about it?
How much does it cost to replace the catalytic converter on a 1999 Toyota Tacoma
Crawl under the vehicle and look between the engine and the tail pipe. You will see the catalytic converter.
If it is a 4 cyl. it has 2, one in front of the catalytic converter (Upstream), and one after the catalytic converter (Down stream).
It has one.
I've recently replaced both oxygen sensors on a 96 Tacoma 4x2. "Sensor 2" is the one after the catalytic converter. It's on the exhaust pipe, a few inches behind the converter. Held in place by 2 nuts. Electrical connection is attached to truck frame.
According to the Haynes manual for 98 Toyota tacoma, and a mechanic i just visited, two. One on each side of catalytic converter. correction, there are two sensors, the first is an air fuel ratio sensor, and the second is the oxegen sensor. i know cause i had to replace both of them. opie909
I'd like to expand on your question concerning the catalytic converter on your 2002 Tacoma. Not to be argumentative with the person who responded and he is partially correct. OEM does mean original equipment manufacturer, but there are aftermarket cats that are OE type. There is nothing wrong with OE type aftermarket products, we buy them every day. Oil Filters, Brake Pads and Shoes, Front End Parts, Exhaust Systems, Batteries and so on. There are quality aftermarket catalytic converter manufacturers here in the US that make bolt on direct fit units to fit your vehicle. In addition there is really no such thing as a high flowing catalytic converter and the so called test pipe bit the dust some 12 years ago. In most states it is strictly against the law to tamper with a vehicles emission system and with 1996 and above OBDII systems you'd be crazy to even attempt it. Besides voiding any existing warranty on the vehicle you run the absolute certainty of the on board computer lighting up like a slot machine. Anyway to answer your question more completely check out the link below. http://www.discountconverter.com/catalytic_converters_news/news_page.cfm?Key=catalytic_converter-&News=2
Check for a loose catalytic convertere heat shield
All o2 sensors are located in the exhaust stream between the manifold and the catalytic converter and usually one after as well. they are the only things with wires connected to the exhaust and are always on the top side of the exhaust pipe.
2001 Toyota tacoma bank 1 means that it is located before the cadalic converter.
