Having trouble with my 1998 Dodge Dakota 3.9L V6. I need to find out what diagnosutic trouble code P0545 refers to. Can anybody help?
The truck idles rough but did pass emissions. I just replaced both O2 sensors before the emission test thinking that they were bad at 80,000 miles but they did not have an effect on the rough idle. I found out what the error code was when I had it emission tested.
Any help is greatly appreciated.

The code P0545 refers to the A/C clutch relay circuit. Cant see how that would effect your idle but you do have a problem there.

 

Post your e-mail and I'll send you a list of all the codes
