P2608: Your Car’s Cooling System Needs Attention
The P2608 code refers to the Intake Air Heater ‘B’ Circuit High. The Engine Control Module (ECM) uses an Intake Air Heater (IAH) to warm the incoming air for proper cylinder combustion. The IAH relay is grounded by the ECM to energize the heater during cold operation.
The IAH is commanded ON when the engine coolant temperature is below 40 C (104 F). The IAH heater is supplied power by the battery positive voltage circuit through the IAH relay.
