#1: O2 sensor issues? Author: londonboards, Posted: Sat Nov 04, 2017 2:45 pm ---- Hello
Newbie here.
I've been through lots of posts about testing the O2 sensor (which I am doing as I have the usual cold idle speed issues) but I can't find the solution.
It seems that the 2 leads to the O2 sensor heating element that supply the power are only sending 2.1 volts. Obviously the heater won't work and the O2 sensor will give incorrect readings until it heats up with exhaust gasses. Which could explain my idle problem.
Does that mean the ECU is not sending the correct voltage?
Is that an ECU problem? or something else. Maybe the ECU has stopped the voltage as it detects a fault?
The heater circuit on the O2 sensor is reading 4.2 ohms. what should it read?
Greetings
It's on a V reg 206 with 1.4 engine

Scanner works on my other car (Volvo V70 from 2002)
Looks like a trip to the garage to read the codes.
