Sorry for all the threads guys.
Following on from my other thread:
I've seen some guides showing you how to test lambda sensors by putting a multimeter on the wires and then heating them up, but they always seem to be for other cars with about 3 wires.
Does anyone know how to do the same test on our 5 wire lambda sensors?
I would need to know what wires to put the multimeter on and what reading i should expect.
