guys this morning I have the mil light on and have read the codes and comes up with p0031 bank 1 sensor 1 not too sure on the description of the fault code I have tried clearing the fault with the scanner I have but it just keeps coming back within 2-3 miles of driving anyways I have tested the top right lambda sensor to see if there is any resistance through it with a voltmeter using the ohms setting and there isn't any readings at all tried the left hand sensor and I have a reading on this one would you say the sensor is kaput I believe it is the car hasn't lost any power or mpg at the moment but due to being booked in for the MOT next Friday I think its best off changing it due to emission's test am I correct in thinking this car is a 55reg 2.0 vvt-i any advice appreciated Steve
