avanbueren Posted March 9, 2015 Report Posted March 9, 2015 have the error coming up reset the emginemanagement lighyt but after 100 or so miles it came on again with same fault Have a galaxy Mk2 2.3 petrol which has done 105K miles any ideas what could be causing fault code to appear Quote
BrianH Posted March 9, 2015 Report Posted March 9, 2015 Does bank 1 sensor 2 ever change from 0v? if its staying on that static then I'd check its correctly plugged in for starters. Could be a faulty sensor, could also be a faulty cat although the sensor reading looks like i'd suspect either the sensor or wiring to the sensor first. if you can get access to an exhaust gas analyser that should tell you if the cat is working or not.

sparky Paul Posted March 12, 2015 Report Posted March 12, 2015 (edited) Agree, looks like the post cat lambda sensor kaput. Also check for damaged wiring, it's a bit vulnerable under there. My mark 1 doesn't have one, but I understand the later ones do. Edited March 12, 2015 by sparky Paul Quote
