Hello, I have a 2007 5.9L and at about 3000 miles the check engine light came on. I took it to the local dealer and they said the code was P2609 and replaced the intake heater. I drove 2 days and last night while warming the truck up the check engine light comes back on! I have tried the cycling of the ignition but this does not seem to work on 2007. This is my 1st Dodge and my last truck was a 2003 Ford powerstroke. I thought I would buy a Dodge to try them out. Hope this is'nt a preclude of things to come. Truck only has 3400 miles on it! Any help on how to retrieve codes on a 2007 cummins? Thank You, Grant.

 

I just new here gw, but on my 2001 I can turn the ignition switch on and off 3 times fast and while your in the 3rd on position, watch your odometer. It will give you any error codes that can be goggled.

Good Luck!

 

Mine works the same way.....

 

I have an 06 but it still does the same for me.....

 

I tried the key cycling again and it worked. Same code as the dealership said they addressed. Intake heater. I looked at where the intake heater is and I highly doubt the dealership I took it to was able to change it out as they said they did in 1/2 hour. What do you folks think. Anyone else with this problem?? Thanks, Grant.

 

yes you could change a grid heater in 1/2 hour...if they did may be another story
you don't see to many grid heater codes on our truck they seem to work really well.

 

I just got my 2006 CTD back from the shop with the same problem. They had my truck for 3 weeks. They ended up putting a new ECM in it New Batteries and wire harness. seems to be working fine now, I would push for the ECM if you still have problems. By the way the dealer I took my truck to said that they had created a TSB base on my trucks problem. So there is a fix!!

 

Sure, grid heater on a 5.9L is an easy half-hour.
