I have a 97 Plymouth Voyager with a 3.0 and 3 speed tranny I have been fixing back up. I did notice the speedo was showing a wrong speed. Maybe 10 - 15 mph off. I went and did the pcb resolder to fix the gas gauge problem and thats solved but why is the speedo off? I did the dash calibration test and the only codes that show up are in the beginning of the test (Code 999 then Code 0). When it starts sweeping the needles, the speedo goes from o to 10, then to 45, then to 65 then all needles drop and goes to next test. When done, I am left with the tripometer and no codes.
Does it need some type of speed calibration or is it a sensor? Is there something I can do or does it need to go to a shop?
