Pulled my MAF sensor at the weekend with the intention of giving it a clean. My sensor seems to be missing a part, looks like it's supposed to have some external wire and a resistor.
Mine looks like this
Should it actually look like this???
I just assumed that i must have knocked the wire off when i removed the sensor so I put one on order from eurocarparts. However the car runs fine with no CEL with the MAF refitted.
Help would be appreciated as if it's not supposed to have this wire attached I may be wasting £60.
