Good morning everyone, Mitsubischi L200 year 2007 2500td engine KB4T engine warning light on but not always and car that yields little, made diagnosis we have n.2 error codes P0102 low air flow circuit signal and P0638 throttle valve control servomotor blocked in fact both the throttle valve and the egr valve checked with the diagnosis do not give values as if they were blocked, we have replaced the air flow meter and now the car runs well and the values of both the egr valve and the throttle valve are normal, most likely the malfunction of this sensor (air flow meter) is correlated with the operation of all the other organs.

Good Work.
