Two problems related to speed sensor have been reported for the 1998 Plymouth Neon. The most recently reported issues are listed below.
These problems were found during a replacement of our third transmission. We are really upset with Plymouth/Dodge auto. We had this car for only a year and it has been nothing but trouble. Like I said, 3 transmissions, 1 engine due to head gasket problems. Now, the oil pressure sending unit, vehicle speed sensor, and the rear main oil seal. ----dims 11 ivoq entry after 12/12/01 cut-over to artemis-------769336.
When brake is pushed the turn lights would light up and brake lights wouldn't brighten. This was (08/13/01). In 10/10/01 was able to drive forward in reverse and neutral, didn't have a reverse, transmission replaced. In 03/12/02, found oil in the antifreeze reserve and radiator, replaced engine due to head gasket problem. In 04/15/02, transmission doing the same thing back on 10/10/01 , transmission is replaced again. In 10/31/02, transmission replaced for the third time, due to shifting hard, and same problem as 10/10/01 and 04/18/02. Also, at the same time the speed sensor went out so there was no speedometer working. We also had to replace the rear main oil seal because it was leaking and replaced the oil sending unit. ***dims 11 ivoq entry posted after 121/12/02 cut-over to artemis--------769334.
