Question about 1999 Dodge Caravan
P0734 is a transmission code. The code description is: Additional gear ratio in fourth gear. The most likely cause is the input speed sensor on the transmission, a common problem. The sensor is located on the side of the transmission facing the grill right above the solenoid pack. You need to check the resistance of the sensor. It should be between 500 to 700 ohms. If it tests open, the sensor is bad. If not check the connection and the wiring.
