Consumer Description

SERVICE ENGINE SOON LIGHT WAS ON AFTER COMPLETING A DIAGNOSTIC TEST AT A LOCAL DEALER THEY SAID THE MALFUNCTION WAS THE SECONDARY AIR INJECTION(AIR PUMP) CODE P0410. THEY SAID THE REASON THESE GO OUT IS BECAUSE OF AN ENGINEERING DEFECT AND THE WAY THEY ROUTED THE HOSES INSTEAD OF AIR FLOWING THROUGH IT CAUSES WATER TO ACCUMULATE THEREFORE MAKING THE MOTOR IN THE AIR PUMP TO GO BAD. SO WHILE CHANGING OUT THIS BAD AIR PUMP THERE WAS SO MUCH WATER THAT HAD ACCUMULATED IT ACTUALLY CAUSED THE LIGHT TO BLOW WHICH COULD HAVE CAUSED THE MECHANIC TO BE ELECTROCUTED! *TR
