Hi all
I had a P0140 code after the check engine light came on yesterday. Cat below threshold. Checked O2 sensor outputs and this code may not be cat on way out but also gets generated if both O2 sensors read close together!! The front O2 sensor was reading high all the time. Mainly above .45V, round .7V to .8V with slow switching. The rear O2 sensor also reading high and fluctuating. I found an old O2 sensor in the garage and thought I'd try that, symptoms changed but not corrected. This O2 sensor reading high, then low, then the voltage dropped. Checked the voltage with a DVM. Low after start up warm then drops to 0V. New code came up. P0170. Fuel bank 1 at 0%. I searched the web for the fault code and got this up.

I wrote it last year, USING THE SAME LAMBDA SENSOR I USED when I got this fault. About the same week last year!!! What a moron.
You've got to laugh. I'm throwing both sensors away and replacing both on the car. I've even done a compression test 200lb 210lb 200lb 200lb.
I was like "errr P0140, I think I've got a lambda in the electrical draw some where, err, I'll try it. For some reason I think it might be U.S. It can't be any worse than what I've already got. Yes I'll use it". Bang P0170.
Still my other thread is a good read and explains what is wrong with my O2 sensor.
Do I believe myself and the last thread, yes of course I do, I've done it twice now with the same parts.
Now, am I now regarded by the pure and righteous as a knob head who uses the broken parts he should have throw away?
Vote now.
