Mitsubishi Repair: code problem, vehicle speed sensor, exhaust gas recirculation

Question
hi my mitsubishi galan es 96 reads a p1500 and p0400 code can you please help me what can i do to repair this codes thank you  

Answer
David,
P1500 represents a bad signal from the Vehicle Speed Sensor.  You should have the sensor inspected and replaced if neccessary.  Code P0400 indicates an Exhaust Gas Recirculation Flow Malfunction.  This can be caused by a number of things, but the first thing your mechanic should inspect is the EGR value.  If the valve is faulty, you'll need to have it replaced.
Good luck!
