I recently bought a 95 s90 and I absolutely love it, but I'm having issues with the cel I knew about it when I purchased the car and reading them has got me stumped, I put the connector in socket 2 on port A and I get codes 112 and 212 I'm sure 212 is the oxygen sensor but I've read 112 could be ecu failure or fault in the fi control unit, how do I go about fixing this? I'm stumped on if it's the ecu or the fi unit, it's a 2.9 liter if that helps, thanks in advance
