What controls current to the intake air heater?
Air heater elements are used to heat incoming air into the intake manifold. This is done to help engine starting and improve drivability with cool or even cold outside temperatures. Electrical supply for the two heating elements is controlled by the engine control module via two air heater relays.
What does an air intake heater relay do?
It sends voltage to the intake air heater when the PCM tells it to. It’s meant to help reduce white smoke on cold starts and idle. It’s not necessary for the truck to run.

This particular air intake heater relay code indicates circuit low, meaning that the voltage is lower than the range it should have.
How does a flame heater glow plug work?
Flame Glow Plugs
These devices use a relatively low power electrical heater to ignite a metered amount of fuel. Heating powers of up to 10 kW are possible with these heaters. Fuel from the fuel inlet is evaporated over a vaporizer tube, mixed with the intake air and then ignited on the heater rod.
Why do a grid heater delete?
Registered. It deletes the heater that warms the air prior to starting the truck. Your truck should run better without it and in the winter you will need to have it plugged in when it’s gets cold.
What is a grid heater 5.9 Cummins?
The 5.9L Cummins does not have glow plugs, but rather a single heating element mounted between the air horn and intake manifold referred to as the “heater grid” or “grid heater”. The heater grid is a resistive heating unit that operates on similar principles as a traditional glow plug system.
