Vararam check engine light

[Nito209]

Hey I just installed a brand new vararam CAI on my 2013 1500 purchased from MOES Performance, After going on a road trip the next day the check engine light came on. I disconnected the negative terminal for the battery for an hour before heading out for the CPU to get use to the new CAI. I did it again for another two hours when the check engine light came on.Has anyone else come up Witt This issue? I am going to reinstall the stock If this this still becomes an issue. I have a 14inch magnaflow muffler installed also and that is the only modds I have right now.

make sure the sensor is in the correct position. i think its called the AIT sensor.

As stated above make sure the sensor is in the right position, also make sure that your clamps on the hose for the throttle body are tight, have you checked what code you are getting with the check engine light on this may allow us to help you better.

Thanks

Yeah shouldn't get a CEL from a CAI install, x 2 above.

I've had mine on for a month no issues - The Sensor feel out a few times while installing it(I don't like how it mounts) So I just put a dap of sealant on it.

Hmm- wonder if the sensor got damaged when it fell out?

You may have a vacuum leak or other unrelated emissions failure. Can't tell without the code. Its a pain to restore the stock intake only to find something more is going on.

I'm a different guy - I have no issues

The code is most likely due to the IAT sensor being unplugged and then plugged back in. Just clear the code or reset your computer, and you should be good to go. There is nothing else related to the intake that would trigger any kind of engine light. Make sure the locking tab on the IAT sensor is facing up towards the filter tray and that it has a good connection to the wiring harness, and you should be good to go.

I keep dealing with a CEL for a P0456 code as well. It has been the ESUM, Purge Solenoid and apparently something new this time. I also have the Vararam but I don't think that is the cause. I get the code without it on.

Sounds like he unplugged it during install and has cleared it since?
I would check wiring and air connctions then.

I cleared the code and It has not come back on. I just drove it in the city for now. I will take it for a trip on the freeway and hopefully the CEL doesn't come in.

This is normal for most guys when installing an intake. Anytime I have unplugged an IAT sensor, I almost always have to either clear that code or reset the computer to turn it off. It wont hurt the truck if it is unplugged, but it will always throw that code on the first startup. That is a part of the reason why I recommend unplugging the negative battery terminal during the install. This automatically resets the computer so that the code doesn't pop up on the initial startup.

I unplugged TB, Map Sensor, IAT over past 2 days of working on my truck and Luckily the Negative cable was not on the Battery! Matt you offer great follow-up advice to your customers and after sale support. I gotta say the 4th Gen Trucks are coming along nice as the Mods become more and more available and CAI is definately a good start. Happy the OP is good to go on to his next Mod.

Well it looks like the check engine light came back on. I decided to put back the stock intake and will see if the check engine light comes back on. I installed the vararam precisely as the instructions said. So I will keep this thread updated as I drive the truck with the stock intake.

 

[Hemi450hp]

What is the code number that you are throwing? The only item related to the Vararam that could trigger a code is that IAT sensor. If it was damaged during the install, then it should trigger a code regardless of which intake system is installed on the truck. If it does not throw a code with the stock intake, then that means the IAT just was not installed properly in the Vararam coupler or it was just not getting a good connection with the wiring harness.

 

[Nito209]

I will let you know if a check engine light goes on with the stock intake. I could not get a code because the dealership I bought the truck from is a couple hours away and just decided that I would put the stock intake back and see if the CEL pops up.

 

[Nito209]

So I finally took the truck to pepboys to check the code for my check engine light. I got P0714 trans fluid temp sensor a clt intermittent. Does anyone know what this means? I have a service appointment tommorow with my dealership so I'm going to take it in and get it fixed.

 

[Hemi450hp]

Glad to hear the intake wasn't causing the code. I have never heard of the tranny temp sensor going bad on these trucks, so it most likely is just a loose wire or the sensor just doesn't have a good connection.

 

[Nito209]

Yeah I looked at the connection it looks well connected maybe its the sensor itself. Hopefully when I take it to the dealership they can further evaluate it and fix it. Man I've only had the truck for only 900 miles this sucks.
