There are 4 of them on the 3.2L engine, I'm sure it's similar on the 2.2L. They are located on the exhaust pipes under the driver and passenger floor wells. You will need one down and one up on each side, I feel that the Bosch brand was the better sensor, I went through 2 of the cheaper (generic) ones in a few months.
The best way to get to them is to lift the truck and have a really skinny friend reach up there to remove them with a wrench, I'm not a a huge fat guy, but the oriental guy in our shop had to help me with these. LOL, so I will give credit to Wu for the help....
oxygen sensor
The Isuzu Rodeo can have 3 or more oxygen sensors. The oxygen sensor delivers information to the powertrain module.
On exhaust manifold.
It may be located in the airbag sensor control unit.
The check engine light for the 2001 Isuzu Rodeo often comes on because of a sensor that is damaged or malfunctioning. The most common sensor is an oxygen sensor and when reset, this often allows the light to be reset.
it depends on the model of engine, my 97 rodeo with the 4ze1 motor has the map sensor for air intake but doesnt have an O2 sensor for the exhaust.
It appears that the 1993 Isuzu 3.2L V6 engine has just one oxygen sensor. It's a 4-wire type, located at the exhaust Y-pipe outlet. == ==
Specify your engine size, or were they all the same? BClear.
