OBD II Code P-0441 on my 2003 Dodge Ram 2500

While giving a coworker a ride home from work the other day, the check engine on my truck came on. I bought this truck new in 2003 and up until now I have had no issues with it whatsoever. My previous truck was a 1987 Chevy 1Ton, and I recalled being able to get the error codes by cycling the ignition 3 times. Fortunately for me, this worked as well on my Dodge. The trick is to turn the ignition from on to off three times. On the third cycle, leave the ignition on and the odometer will display a code, if any, and then display “none” after  a short pause.

In my case, the code that came up was P0441. A quick google search brought up “P0441 Evaporative Emission Control System Incorrect Purge Flow“. On this page the common problems for Chrysler is the Leak Detection Pump. LDP’s run for about $40 on froogle, so its not a very expensive. More importantly, the information I gleaned off of froogle was what the damn thing looks like. I found the LPD attached to the rear of the gas tank, and to my delight I saw that one of the plastic hose clamps was broken! A quick rigging with some wire and resetting the computer by disconnecting the battery and the error code went away. This weekend I plan on going to the parts store and getting a proper hose clamp, but this quick fix will get me through the rest of the week.
