Hi just had this 'P1131 Bank2-Sensor1' fault appear for the second time in a week also it has a pending 'P2251' (unsure what this is). think these are to do with a Lambda sensor, does anyone know which one and is there a way to test if the sensor is actually faulty? I had two lambda sensors replaced back in Feb so I want to check my self before taking to Jamie so I know if it's a warranty job or not as I pressume they have a year guarantee, and if it's wiring or another sensor I'll do it myself but just need to be sure what I'm checking.
