I bought a scan tool for my Gen IV Viper with 2800 miles on it. This code showed up, no CEL and the car runs perfect. The only thing I have done is installed the recommended skip shift eliminator (again, no CEL). Could this do it? Thanks!

The 09's and up cannot use the normal resistor type skip shift eliminator, they throw codes..

Mine is an 08. Is this code associated with the skip shift eliminator? If so, can I disregard the code. The car drives perfect. Thanks.

No, it's not. The ECT pull up resistor is for the engine coolant temp sensor. It is an internal pcm resistor for supplying the engine coolant temp sensor a set current.

PS that's a gm code description, not dodge. I would need to check the dodge description.
