Title: oxigen sensor pinuot
Post by: blueboi69 on November 25, 2012, 02:25:55 PM

Hi!

I'd like to know what's the pinout of the stock oxigen sensor in an E30 M42.
I have a round connector with two white, a grey and a black wire.
Plz input. :)
Thanks!

Download the ETM, page 30 of the PDF (page 1360-5) shows the schematic for the sensor; page 116 (page 8500-7) shows the mating face with the pinout.

IIRC, the two white are the sensor inputs (pins 1 & 2), the black is the ground (pin 3), and the gray is the lead to the heater relay (pin 4).
