i just installed a cold air intake a week ago the next day check engine light came on the code was p0401 i know that has something to do worth the emissions and everything I've checked days its egr valve but i can't seem find any tutotal or pictures i don't know if i should try to just put the stock intake back on our keep trying to figure this thing out i just barely cut out the family mechanic cause i think he was ripping me off so I've been doing all the maintenance and work myself but i don't really know that much about cars just watching u tube videos

 

What is the year of the car and engine type; V6 or 4-cylinder?

P0401 is insufficient exhaust flow for the exhaust gas recirculation (EGR) system.

 

it's a 09 4 cyl 2.4

 

i know it's the egr system but i don't know how to fix it or where to start

 

This engine model does not have an EGR system.

Suggest rechecking the code to determine if it was P0401 or something else.

 

man I'll have too go get it scanned again i was sure that was the code have you heard anything about installing an intake and getting the check engine light or the possibilities

 

Does happen installing an intake can cause codes.

Check for loose or disconnected hoses, clamps, etc.

What brand and model intake?

 

some no name brand but i put the stock in last night and still getting the light

 

If the trouble code was not cleared by a scanner, it may take a few days for the computer to run its systems tests and reset.

Give it a few days and if possible recheck the trouble code number.

 

I cannot tell the difference yet buddy! Supposedly, I want to buy too! However,
