hello, my alfa keeps giving P0130 and what it feels like it is stottering (is that english?) especially in the lower rpm`s
can someone help me out here?
just clean the o2 sensor? or replace?
thanks

Re: alfa 156 1.6TS with faultcode P0130 o2 sensor
did you try to check the parameter and draw a graph of it?
Checking the O2sensor voltage is a good way to know if you have to replace it or not.
check the connector and cables too.

keep in mind the grpah is not a perfect sine wave..

I've been suffering with P0130 and P0170 faults for a while now and it could be you have a non-Bosch Lambda fitted. There are several out there that are fitted because the are cheaper that the correct bosch part. I had an NTK Lambda for several years and this constantly gave P0130 faults. As it was almost dead and only just passing the UK MOT emissions tests by 0.1%(!) I swapped mine out for a new Bosch sensor today.
But rather than spending around £100 on one, I fitted a Universal Bosch LS615 Lambda I bought for £50. You have to cut the lambda cable and screw in the wiring block, but it was relatively simple and didn't need a screwdriver, soldering iron, etc. Just a pair of wire cutters and something to strip 1 cm of insulation from the ends of the wires.
I read somewhere that the NTK Lambda was only 4 ohm impedance, were the Bosch is 8, which may explain why the old one caused some many fault codes while apparently working properly.
