Hi out there. Can anyone help with the two codes? I have a 2005 magnum with a 3.5 L. And more recently the wife says the electronic throttle control light comes on. Please help

 

P0128 is Thermostat Rationality. And that code can trigger ETC light. You should start by replacing the T-Stat and housing, and coolant. AND GET YOU PARTS FROM DEALER!!!! there are revised part for this issue.

The P0441 is EVAP performance. It is a Emission code, doesn't really hurt anything. However, it will most likely needs to be smoke tested for gas vapor leak.

 

Thanx, steak59 - I will replace the t-stat with dealer parts.
