When your Dodge vehicle is showing code P0652, it is indicating that there is an issue with the powertrain control module (PCM) which contains two internal 5-Volt Sensor Supply sources. This code stands for “Sensor Reference Voltage 2 Circuit Low” which means the PCM will shut off the 5-Volt Supply circuit if it senses a short to ground or if one of the sensors is internally shorted. Luckily, there are several causes and solutions for this Dodge Code P0652.
Causes and Solutions for Dodge Code P0652
| Cause | Solution |
|---|---|
| (F856) 5-VOLT SUPPLY SHORTED TO GROUND | Check for a short to ground on the powertrain control module (PCM). |
| (K854) 5-VOLT SUPPLY SHORTED TO GROUND | Check for a short to ground on the powertrain control module (PCM). |
| MANIFOLD AIR PRESSURE SENSOR (MAP) | Replace or repair the manifold air pressure sensor (MAP). |
| CAMSHAFT POSITION SENSOR 1 (CMP) | Replace or repair the camshaft position sensor 1 (CMP). |
| CAMSHAFT POSITION SENSOR 2 (CMP) | Replace or repair the camshaft position sensor 2 (CMP). |
| ACCELERATOR PEDAL POSITION SENSOR (APP) | Replace or repair the accelerator pedal position sensor (APP). |
| TRANSMISSION SOLENOID/PRESSURE SWITCH | Replace or repair the transmission solenoid/pressure switch. |
| POWERTRAIN CONTROL MODULE (PCM) | Replace or repair the powertrain control module (PCM). |
When your Dodge vehicle is displaying code P0652, it could be a sign that you have an issue with the powertrain control module (PCM). This code stands for “Sensor Reference Voltage 2 Circuit Low” indicating that the PCM has detected a short to ground or an internal short in one of the sensors. To solve this Dodge Code P0652, you must check for a short to ground on the PCM and replace or repair any of the affected sensors or the PCM itself. Knowing the causes and solutions for this code can help you diagnose and fix the issue quickly and effectively.
