Hi everyone!
I am looking for the pins assignment of the oxygen sensor in my Bravo 1.6SX if any one can help me find some informations about it (PS: it has 4 wires). thanks alot.

haynes manual tells you whihc wire is which. on any 4 wire lambda sensor there are always 2 signal wires and 2 heater element wires. if you're wiring a universal 4 wire lambda onto your car, dont bother they are a waste of time and money. your injection system fault light will almost certain stay illuminated after fitting it. get one designed for the car with the correct wiring connector.
