How is it possible for this to come on when I\'ve removed the sensor from the cat and the wires have been soldered together as Carl recommended?
Basically my car isn\'t working 100% but for once it went full boost and when I came off it the light came on for about 10/15 seconds then went off and hasn\'t come back on. It\'s never done it before.
Does the PFC report anything through that light or something?
