Fix code P0750 P0755 P0760 P0765 Chrysler Minivans
The solenoid pack in these Chrysler vehicles regulates transmission oil pressure to activate the clutch packs and make the vehicle shift. The solenoid receives a pulsed signal from the PCM and the solenoid responds by opening and closing the port up to 10 times per second. This action is called “duty cycling.” So if the solenoid is open 5 times in one second, it’s at 50% duty cycle.
The PCM constantly checks the condition of the solenoid pack and reports any of the P0750, P0755, P0760, P0765 trouble codes when it finds a problem. Then it puts the vehicle into “limp in” mode so you can drive the vehicle into the shop. To confirm that the problem is actually the solenoid pack all you need is a digital multi-meter. Disconnect the electrical connector from the solenoid pack and test the resistance between pins 1 & 5, 1 & 7, and 1 & 8. The yellow/red wire goes to pin 1. All the solenoids should read 1-3 ohms. If the readings are out of range, replace the solenoid pack.
