Where is the O2 sensor on 1993 Toyota Mr2
Look on exhaust manifold.
The Oxygen Senson #1 (Upstream) on a 1997 Isuzu Trooper is located under the vehicle and on top of the exhaust, just under the front passenger side. The easiest way to access and replace the O2 sensor, put the vehicle on a lift. Follow the exhaus pipe from the motor on the passenger side. There, you will see the #1 O2 sensor. First disconnect the o2's eletrical connection before removing (simple clip connector) An adjustable wrench will remove the O2. Replace with new O2, but do not overtighten! Reconnect the electrical connection. Done!
Right next to the oil filter
The 1993 Chevrolet K 1500 pickup truck 02 sensor is on the back of the air cleaner housing. The O2 sensor should be labeled as such.
A person should be able to trouble shoot problems in a car. A vehicle would stall out after starting because of a failure in the fuel system, or it could be a bad O2 sensor.
For the 1993 Toyota Tercel, the O2 sensor has three different wire colors. These colors are: black, blue, and white.
the o2 sensors are located on the exhaust pipe one by trans and one by the muffler there is 2 of them
You have a bad o2 sensor (low voltage)
