| POWERTRAIN CONTROL MODULE (PCM) | Replace faulty PCM |
When your Dodge vehicle’s diagnostic system reads a P0642 Code, it indicates that the Sensor Reference Voltage 1 Circuit Low is causing an issue. This code is typically associated with a faulty part, shorted wiring, or debris blocking the connection. It is important to identify the root cause of the problem to make sure that any repairs are necessary and effective. Knowing the causes and potential solutions for a Dodge P0642 Code can help to make the diagnosis and repair process smoother. In this article, we will review the common grounds and possible solutions to help you diagnose the issue and get your vehicle running smoothly again.
5-Volt Supply Shorted to Ground
The first cause of a Dodge P0642 Code is a 5-volt supply shorted to the ground. This is typically due to a wiring issue or damage to the cable. It is important to check the wiring for any damage or exposed wires and repair it if necessary. This is a simple fix and can resolve the issue quickly.
Crankshaft Position Sensor (CKP)
Another common cause of a Dodge P0642 Code is a faulty Crankshaft Position Sensor (CKP). This is a common sensor that can become faulty over time due to wear and tear. If the CKP is the cause of the issue, it is important to replace the faulty part as soon as possible.
Oil Pressure Sensor
The oil pressure sensor is another potential cause of a Dodge P0642 Code. If this sensor is causing an issue, it is likely due to debris blocking the connection. It is important to check the link and clear any waste or obstruction to ensure that the sensor is working correctly.

Throttle Body Assembly
The throttle body assembly is another potential cause of a Dodge P0642 Code. If this is the cause of the issue, it is likely due to the connector being damaged. It is important to inspect the connector for any damage and repair it if necessary.
Accelerator Pedal Position Sensor (APP)
The Accelerator Pedal Position Sensor (APP) is another potential cause of a Dodge P0642 Code. If this is the cause of the issue, it is important to calibrate the sensor to ensure it is working correctly. This is a simple process and can resolve the issue quickly.
Powertrain Control Module (PCM)
Finally, the Powertrain Control Module (PCM) can cause a Dodge P0642 Code. If the PCM is the cause, it is important to replace the faulty part as soon as possible. This is a vital part of the vehicle’s computer system and can cause serious issues if it is not functioning correctly.
Conclusion
When diagnosing a Dodge P0642 Code, it is important to identify the root cause of the issue to ensure that any repairs are necessary and effective. Knowing the common causes and potential solutions can help to make the diagnosis and repair process smoother. From a 5-volt supply shorted to ground to a faulty Powertrain Control Module (PCM), there are a variety of potential causes for a Dodge P0642 Code. With the right knowledge and information, you can quickly diagnose and resolve the issue with your Dodge P0642 Code and get your vehicle running smoothly again.
