Engine light because of after market air filter? 2020 2500 diesel

I should have been more specific. My Ram dealership diagnosed it. In fact they left their little code reader connected and I drove home with it. It's hard to believe that the truck suddenly doesn't like the filter after at least 8000 miles. Total miles is only 16.7k

$2,000 micropod? Nice.

LOL
 
$1600 annual fee also right?
There’s several options, but if you’re working with just one VIN only, you can get by with $40/month for wiTECH 2.0, then you need at least a 3 day $37 techauthority subscription to flash.
 
Anybody know if the engine light goes off by itself after the appropriate fix has been done? I replaced the air filter with a Mopar as told by the dealer but the engine light is still on. It seems that talking to a service tech is like trying to talk to the president. I've only driven it once since changing the filter.
 
I bought a brand new K&N filter and as soon as I installed it, Check engine light came on. I cleared it with my scanner, but it kept coming back on. I put in the old dirty filter
back in just to see what happened, and check engine light did not come back on after clearing it.
I bought a brand new paper filter from Orielly's, and light has not come back on. It did not like the K&N.
 
Thanks for the info. So you have to have a scanner to clear the engine light? I've heard some say it clears itself after a few driving cycles.

That's because it knew you got a K&N and it didn't want to be fed a steady diet of dirt, so it threw the code!

Be happy it threw a code, the K&N filters are not known to be turbo friendly.

Stick with OEM filters.
 
I was told that my engine light came on because of not having an OEM air filter. I'm highly suspicious since whatever filter is in it has been there for the last 8000 mi. (I bought the truck used) I recently had my CP3 replacement done so they're saying that because of that, the filter problem is now showing up. Anybody else experience this?
yes, it’s happened to me before . i spent $150 to fix engine light problem in dealership, but the light came back later in . then few months later , when i replaced my air filter in dealership, they told me the air filter coz that engine light on . i have no issue so far .
 
Thanks for the response. I'm still waiting for the engine light to go off. I don't drive the truck much. The dealership is horrible...terrible communication. I can't get a simple answer about the engine light reset without driving over there.
