Heated oxygen sensor circuit

Where is the fuse/ relay
Located 2002 landrover freelander v6

The LR Rave workshop manual will tell you. There's info on downloading it on this thread...

Make sure you download the right one for the V6. Needs to be installed and run on a Windows PC and needs a driver to open the ISO image as a drive letter.

It has full circuit diagrams - so you can check that from the presence and identifiers of fuses and relays. There are location images for all connectors and if there's not of the fuses/relays you can work that out from the connectors on the circuit diagrams attached to them.

No fuse or relay for the O2 sensor heaters.
The O2 sensor heaters are fed directly from the ECU, as that's the only way it can monitor the circuit.

What are you trying to do?

I replaced my o2 sensors with generic
Ones
Now I have afew cel codes
P0056
P0036
P0150

need to figure out if I have bad wires connections
Or buy the oem oxygen sensors
Could the circuit be blown inside the ecu?
