Where is the bank one o2 sensor on an Isuzu Rodeo and how do you change it?
On a 2003 Isuzu the O2 sensor is on the driver side of the engine compartment about a foot down from where the exhaust pipe comes out of the header. Just follow the exhaust pipe out of the engine and you will see it. It looks like a spark plug sticking out. It’s pretty easy to disconnect the wires, unscrew it and replace it. You will need a 7/8″ open end wrench to unscrew it. Good luck. * 1999 Oldsmobile Aurora’s actually have 4 O2 sensors, 1 on each header and 1 before, and 1 after the catalytic converter…
