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 … Read More

You will need a scan tool with bidirectional capabilities to perform this programming.   © 2012 Rick Muscoplat

Chrysler EVAP System

How the Chrysler EVAP System works The Chrysler EVAP System is different than most other EVAP systems. Here’s how it works. All vehicle manufacturers are required to build in test sequences to detect a possible leak of fuel vapors into the atmosphere. They can do this two ways: by adding pressure to the system or by pulling a vacuum on the system. Starting in 1996 Chrysler used a pressure technique using a leak detection pump (LDP) to check for system leaks. Ironically, LDP is basically a vacuum/spring driven pump. It … Read More

In the OFF position, you should see no continuity. In Delay 1 you should read 792-8080 ohms, 2= 5940-6060, 3= 4455-4545, 4= … Read More

Fix trouble code P0401 egr insufficient flow – Chrysler Minivan Late model Chrysler Minivans are known to post P0401 egr insufficient flow codes P0401-P0408. The egr valve is like an electronic solenoid that pulls the pintel off its seat. A position sensor at the top of the valve measures how far the pintel shaft has actually moved versus how much the computer commanded it to move. It’s the position sensor that goes bad (see plunger in photo). The problem may be in the sensor, but the fix is in replacing the … Read More
