Lambda sensor

[Drinky1]

Hi everyone first time on here just bought myself a chimaera in need of some TLC one of the lambda sensors is getting hot whenever the battery is connected anyone have any ideas whats up ?

It's strange just one is heating up with the battery is connected - the power to these is controlledby one of the two silver cased relays adjacent to the ECU (all stuffed ontop of the battery. First thing would be to disconnect these, of the top of my head its the one with the heavy orange wires (IIRC, the purple wired once is fuel pump so it wont hurt to disconnect both)

If this cures matters its a stuck relay, replacing it will sort part of the problem...it could also be that the heater in the sensor that is not heating up is knackered...

Might be worth checking the correct relay has been fitted too.
If the wrong one has been fitted (if you have just bought the car)then you will get a dead battery over night due to the symptoms you describe.
