2002 Isuzu Rodeo Question heater circuit oxigen sensor

Hi maurice.H,

Sorry our database does not have any diagrams to show you. O2 sensors are located on the exhaust, you can't miss it if you look at the exhaust manifold and notice any sensor with 4 wires attached to it.

Being a 6 cylinder, at each exhaust you would see 1 before and another after the catalytic converter, a total of 4 sensors.
