I've sorted code 31 I'm only running 0.8 boost it doesn't go any higher I re connected the wires and took the terminals off the battery and the code was clear took the car out tested it again and just came up code 52
The knock sensor is damaged I put it on and it was my brothers old one that he replaced I didn't know - I've recently put a fcd on would that be anything to do with code 31 ?
Have eml light on my glanza and doing a diagnostic it comes up code 31 which is map and 52 which is knock sensor . Il replace the knock sensor but what do I do about code 31 or are they linked ???
