EGR insufficient flow code

What does this mean, and what do I need to look for?

I cleaned my MAF with MAF cleaner and my code went away. Has been gone for 2 months.

Is this truck an 05+ model? Do you have an EGR delete?

your pcm looks at inputs like MAF, IAT2 and EBP to detect EGR flow. you need to look at things like biased sensors, your EGR valve being stuck shut, cooler plugged or (if you are not the original owner) an EGR cooler bypass/blockoff. obviously if p0401 is the only code then the valve is still intact and plugged in

an insufficient flow code by itself makes me suspicious. what year is the truck? how long have you owned it?

The truck is an 05 and I bought it new. The truck does have an egr delete, and so does my 04 and 07, and they have no codes. Thats what was throwing me off. Im also getting a code for the EBP sensor (sorry, cant remember all the numbers) so that could be part of the problem?

Theres a few more codes that could be part of the problem too. Ill go scan the codes again and post them. The truck runs fine otherwise, just hate that light starring at me.

03-04 trucks won't trip a "check engine" light with a delete. 05+ trucks are hit and miss on whether they will or won't trip the light. I think you have gotten lucky on the 07 truck and the 05 you didn't. The only way to keep it off is to get an SCT with a custom tune to shut the EGR system off. The EBP sensor could either be dirty causing the code or the wiring harness pigtail could be damaged.

Your probably right. I just checked the codes and got nothing but the 0401 code. A couple weeks ago I was getting an EBP code, I cleared them out at that time. The truck has been drove several thousand miles since I cleared them, so the code should be back if there is a problem with the EBP sensor, right?

Also, a code not related to this, but the 07 fuel gauge acts up at times. I will read nothing and the fuel light comes on. Its giving a code 0460, fuel level sensor A circuit. What does this mean? Sounds like a PITA.

If there is a problem with the EBP sensor then the code will return. You could remove it, clean the sensor and tube and it may never come back. As far as the fuel level sensor circuit, I would say that the sending unit in the tank could be causing the issue.

theres a tsb for a P0470 ebp code generating only in cold weather due to the tube freezing up. you need the latest calibration to fix that concern

as for the insufficient flow dtc it seems like every truck is different. mine will set the light then a few days later it'll go out

sounds like you need a sending unit on your 07

I think I'll go ahead and clean the ebt sensor and tube. It hasn't ever been cleaned, and I know I've got that code more than once.

I bet the sending unit will take awhile. Its a 1 ton with a utility bed.
