The thermactor air pump fuse controls the electrical supply to the thermactor air pump, which is part of a vehicle's emissions control system. This pump introduces fresh air into the exhaust stream to help reduce harmful emissions during cold starts. If the fuse blows, the pump will not operate, potentially leading to increased emissions and failing an emissions test. It's crucial for maintaining compliance with environmental regulations and ensuring optimal engine performance.

The PCM controls the EAM relay which controls the EAM air pump. Check: The 30 amp fuse label "Thermactor Pump Fuse." Voltage to the air pump should be battery voltage. The air hoses on the air pump for damage or blockage. Check the vacuum hoses to the one or two vacuum controled air diverter valves. PCM controled vaccum switch for deverter values.
