If your Cummins-powered Ram is having trouble starting in cold weather, the problem may be with the air intake heater relay. This relay is responsible for providing power to the air intake heater, which helps to thaw ice and snow that may have built up in the air intake system.
If your truck is having trouble starting in cold weather, the first thing you should check is the air intake heater relay. This relay is responsible for providing power to the air intake heater, which helps to thaw ice and snow that may have built up in the air intake system.
The air intake heater relay is located in the engine bay, on the driver’s side of the truck. It is mounted on the firewall, near the battery. If the relay is not working, it may be due to a blown fuse, a bad relay, or a problem with the wiring.
If you suspect that the air intake heater relay is the problem, the first thing you should do is check the fuse. If the fuse is blown, replace it with a new one. If the fuse is not blown, the next step is to check the relay.
If the relay is not working, it will need to be replaced. You can purchase a new relay from your local auto parts store. Once you have replaced the relay, the problem should be fixed and your truck should start in cold weather.
Where Is The Air Intake Heater Relay Located On A Cummins Engine?
If you’re looking to find the air intake heater relay on a Cummins engine, there are a few things you’ll need to do. First, locate the fuse box. This is usually located near the battery. Once you’ve found the fuse box, open it up and look for the air intake heater relay. It should be labeled clearly. If it’s not, consult your owner’s manual to find out which relay is the air intake heater relay. Once you’ve found it, replace the old relay with a new one and you should be all set!
What Is The Function Of The Air Intake Heater Relay On A Cummins Engine?
The air intake heater relay is responsible for providing power to the air intake heater. This heater is used to prevent ice from forming in the air intake system. The relay is controlled by the engine control module (ECM).
The air intake heater relay is located in the engine compartment, usually near the air intake filter. It is a small black box with two wires coming out of it. One wire goes to the air intake heater, and the other goes to the ECM.
When the engine is first started, the ECM will send a signal to the air intake heater relay to turn on the air intake heater. The air intake heater will then stay on for a few minutes to make sure that the air intake system is warm enough to prevent ice from forming.
How Does The Air Intake Heater Relay Work On A Cummins Engine?
The air intake heater relay on a Cummins engine is responsible for providing power to the air intake heater. The relay is triggered by a signal from the engine control module (ECM) and allows current to flow to the air intake heater. The air intake heater is used to heat the air going into the engine, which helps to improve cold weather starting.
Here’s a quick rundown of how the air intake heater relay works:
1. The ECM sends a signal to the air intake heater relay.
2. The relay closes, allowing current to flow to the air intake heater.
3. The air intake heater heats the air going into the engine.
4. The engine starts and runs smoothly, thanks to the heated air.
In cold weather, the air intake heater can make a big difference in whether or not your engine will start. If you’re having trouble starting your engine in cold weather, check the air intake heater relay to make sure it’s working properly.
What Are The Symptoms Of A Faulty Air Intake Heater Relay On A Cummins Engine?
If your Cummins engine is having trouble starting in cold weather, it may be due to a faulty air intake heater relay. Here are some symptoms to look for:
1. Engine is difficult to start in cold weather.
2. Check engine light is on.
3. Engine runs rough or stalls when first started.
If you notice any of these symptoms, it’s important to have the air intake heater relay checked by a certified Cummins technician. A faulty relay can cause serious engine damage if not repaired.
Conclusion
One possible location for the Cummins air intake heater relay is in the engine compartment, near the air intake. Another possible location is under the hood, near the firewall.
