Where is the intake heater?
intake manifold
This intake heater protrudes directly into the air stream in the cold side of the intake manifold and blocks approximately 20 percent of the intake path. While the design and use of the AIH may have good reasoning behind it, which is to heat incoming air to alleviate white and gray smoke while the engine is cold.
Why do a grid heater delete?
The heater grid is not a particularly restrictive device, although it can be removed in favor of increased airflow, less air turbulence, and therefore the potential for more power. A heater grid delete is a machined or cast spacer designed to replace the heater grid between the intake manifold and air horn.
What does an intake air heater do?
The air intake heater heats air before it enters the engine in to encourage starting with cool or cold air. Transcript: The intake manifold air heater element assembly is located near the top of the intake manifold. Air heater elements are used to heat incoming air into the intake manifold.
What is the purpose of a grid heater?
The purpose of the heater grid is exactly the same as that of glow plugs – to warm the incoming air charge during cold starts.
Why do we preheat the air intake?
A heated air inlet or warm air intake is a system commonly used on the original air cleaner assemblies of carburetted engines to increase the temperature of the air going into the engine for the purpose of increasing the consistency of mixing of the air and fuel in order to reduce engine emissions and fuel usage.
What does trouble code p2609 mean on an air conditioner?
Trouble code P2609 is triggered by the PCM when it detects a performance problem within the intake air heater system. The circuit may be out of range, contain a faulty component or have improper airflow. Various malfunctions within the circuit may be present and can be physical, mechanical or electrical. Here is an example of an air intake heater:
Which is the correct code for intake air heater?
An intake air heater is an essential component for a diesel engine to assist the starting process. The codes that the Powertrain Control Module (PCM) may set for intake air heater issues include P0540, P0541, P0542, P0543, P2604, P2605, P2606, P2607, P2608, and P2609.
Why does the intake air heating circuit not work?
The intake air heating circuit might not work automatically if the ambient air or engine temperature is above the limit set by the manufacturer. The circuit should activate if it is commanded “ON” with a scanner, or if power is applied manually. Check the blower motor, is it turning “ON”

What is the p2609 code on a Cummins truck?
I have a 2018 6.7L Cummins. This morning, 1st day below 66.9 degrees, my truck threw the code, P2609. I replaced the air filter (it needed it anyway), cleared the code and came right back on. I’m getting 12.94VDC across the battery side of the relay and 4VDC (engine off) from the ECM and 4.5VDC (engine on) from the ecm.

How much does it cost to repair a p2609 Dodge?
The cost to diagnose the P2609 DODGE code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
