O2 sensor sits at approx 0.1v for an age on a hot engine with CO at approx 3% with no re-action to any input from me to stir it into action. Pico-scope will then see it burst into life albeit the trace is a bit crappy and all emission readings come good. Sensor is about 1 year old and made in Italy (No make present). Normally, I would have no hesitation in changing it BUT, cost is £133 plus VAT and have nagging feeling that PO125 is playing a part in this.
