Ok , Started the truck today and the yellow engine light came on again.I just had the truck at the dealers 2 months ago for this and it lit up again..In the manual it says that it has to due with cleaning some emissions equip. What is this and why is this coming on so often. The truck has 40,000 miles and just did this twice in 2 months....Any advice would be appreciated....

 

We would need the codes to make a more educated guess

 

Does P2000 mean anything. Thats what comes up on the cluster

 

I believe the P2000 code is the O2 sensor. This needs to be cleaned or replaced to clear the code. I would alos recommend that you get a code reader and this will provide the information on the trouble codes that you will see. You can also do a search on this site for the codes and see what others have done to fix their issues.
