Citroen C1 three warning lights. engine management, abs and tyre pressure all at the same time

You will have to rectify the fault codes that are triggering the light , otherwise they will return

My C1 is doing the same thing and is in the garage at the moment having the chip replaced for the THIRD time. They say it's because I don't do enough mileage! So sounds like will fail every nine months or so, surely this cannot be right? There must be a way to fix this to last rather longer than a few months.

I suspect this is a common problem. I have a code reader. There were just 2 errors P0139 and P0139 P. That decodes as "O2 sensor CKT slow response (Bank 1 Sensor 2)". I changed the sensor worked for a few days. Now it reports P0137 which is "O2 sensor Circuit Low Volts (Bank 1 Sensor 2)". The same sensor.
Tyre pressure is ok.
All three lights go out when I erase the fault but come back in a day or two.
I use the car every day and have done over 1000 miles in three weeks.

Seems crazy !!!!!!!

Hi, has anyone got any further details to the issue? I have the same lights on my car. First told by garage to replace oil inlet control valve. Lights still on. Now Citroen advised to get a 02 sensor changed and ECU update - has anyone found a reliable fix? Hesitant to spend more money on it now!

I have the exact same problem. I have changed my O2 sensor and that didn't fix the problem. Does anyone else have a fix for this please, not sure what more to do....

Well I did get my O2 sensor replaced. It cost me 100 pounds and the issue is still there. All three lights still on.

Has anyone had their car fixed from this problem . In need of help changed all sensor come back as low circuit bank 1 sensor 2

I have this exact same problem the garage kept fixing it and after a few days or so the light s would come back on, even after replacing parts. They took it to Citroën, who did the exact same thing and it worked.... Until fast forward to today (about 2 years later) and the same 3 lights are back. Feeling like banging my head against the wall!!
