lambda sensor problem

[850_t5]

hi all,

first post on the forum, about my 1995 850 T5 saloon.

Basically, im gettin fault code 2-1-2, heated lambda sensor fault.

i have replaced the sensor, as it was faulty before, also giving out the fault code for sensor signal fault.

i have tested the voltage getting to the heater, which is supposed to be battery voltage, but i only get 3v.

Has anyone else experienced this? Shot ECU is only thing i can think of.

Cheers if anyone can help

Andy

Check the wiring to it.

Mine was melted and hence the sensor showed a fault.
