Attention: TDR Forum Junkies I took my 99 out today for a little ride and noticed that it was a dog (hesitated) badly before boost built up. I thought this is strange, and took it over to Blue Chip. Chip new exactly what the problem was; it was low voltage from the map sensor. A new sensor from Dodge was $96. 00, however Chip removed the old sensor and stuck a small screw driver to slightly bend the diaphragm to a get the correct voltage from the unit.
Apparently the sensor needs to output minimum . 5 volts before any fueling will take place. Mine only had . 2 volts output, thereby I had to get the boost up before fueling would take place and this created the hesitation.
Chip used his scan tool to measure the voltage, however a standard voltage meter could be used for the job. After this quick fix, the truck ran perfect with no hesitation off the line.
This is my first post to this forum and wanted folks to know about another possible problem to hesitation issues. There were no codes set, and the problem came on quickly. Also, this is a easy fix, however one must have a 1 1/4 deep socket to remove the map sensor, and the ability to measure the voltage from the unit.
