Recommended installation for o2 sensor

[Danny]

Does anyone know how to install a 4-wire o2 sensor for vr4 200? My old one uses single wire & it's not functioning properly anymore, so I bought a 4-wire sensor ie. includes heating element and ground.

Any idea where to connect the heating element and the ground?

:lol: :lol: :lol:
this wiring was from a AFR meter product, so for sigle wire O2 i think the signal input no need to connect.. anyone can try and tell does it work??

ground and power are interchangeable.

take a car battery,
tape the + and - direct to the car battery power. turn on ur pen size Turbo timer AFR see got reading or not when the O2 sensor is heated.

:P

I have an idea how it would connect :-

o2 sensor wire - same place as original
ground - ecu
heater (1 wire +ve, 1 wire -ve) - ecu + ignition relay
