How to Replace the Voltage Regulator in a Dodge Intrepid

by Contributor

The voltage regulator for your Dodge Intrepid is contained within the Powertrain Control Module. You can't replace or service it separately. If a problem is revealed with the voltage regulator, then you must replace the entire Powertrain Control Module.

Step 1

Confirm that you have an adequate replacement for the Powertrain Control Module. Make sure you acquired it from a reputable dealer, that it works with your Dodge Intrepid and the voltage regulator works properly (all other circuits, too).

Step 2

Shut the car's ignition off and disconnect the negative terminal from the car battery. These must be off to prevent spike voltage from damaging the module. Note the clock, radio and mileage before disconnecting.

Step 3

Remove the speed control servo and its bracket. This is below and near the Powertrain module and you must reposition them to reach the module. Do the same with the wiring harness, washer bottle filler neck and Transmission Control Module.

Step 4

Extract the Powertrain Control Module. Disconnect the two 40-way connectors from the module.

Step 5

Connect the replacement module (with the replacement voltage regulator) to the 40-way connectors. Install the module onto the Dodge Intrepid, tightening the bolts to about 35 inch pounds of torque.

Step 6

Reinstall and reposition the Transmission Control Module, washer bottle filler neck wiring harness and speed control servo with its bracket.

Reconnect the negative battery cable to the car and reprogram the car's clock and radio. Use a scan tool to program the mileage and vehicle identification number into the new Powertrain module.
