Dodge P0846 Code is a diagnostic trouble code that is triggered when the Transmission Control System (TCS) detects a fault in the 2/4 pressure switch. This code is typically set when the Transmission Control System fails to detect the pressure switch correctly in Park or Neutral, or if the pressure switch fails three times in 1st or 3rd gear. The code can be accompanied by various other related trouble codes and can cause significant damage to the transmission system if left unresolved. Common causes of the Dodge P0846 Code can include a bad transmission solenoid or pressure switch assembly, a faulty powertrain control module, or various other related transmission control system power input trouble codes. To ensure that the transmission system is working correctly, it is important to identify and repair any issues that might be causing the Dodge P0846 Code.
Causes and Solutions for the Dodge P0846 Code

| Powertrain Control Module (PCM) | Replace the powertrain control module. |
The Dodge P0846 Code is a diagnostic trouble code that can affect the performance of the transmission system. When the Transmission Control System fails to detect the 2/4 pressure switch correctly, the code is triggered and the trouble code is set. Common causes of the Dodge P0846 Code include a bad transmission solenoid or pressure switch assembly, a faulty powertrain control module, or various other related transmission control system power input trouble codes. To identify and repair the issue causing the code, it’s important to diagnose the problem and find the root cause. Taking the right steps to repair the issue can help ensure that the transmission system is working correctly and prevent further damage to the vehicle.
Related TCM Power Input DTCs Present
When the Dodge P0846 Code is present, it is important to check for any other related diagnostic trouble codes that may be present. These related DTCs can provide more information and help identify the root cause of the issue. Without this information, it can be difficult to properly diagnose the problem and repair it correctly.
Loss of Prime DTC Present
Another common cause of the Dodge P0846 Code is a Loss of Prime DTC. This code is triggered when the Transmission Control System fails to detect the pressure switch correctly in Park or Neutral. To repair this issue, it is important to check for any other related DTCs and repair any issues that might be causing the code.
(T47) 2/4 Pressure Signal Circuit Open
When the (T47) 2/4 Pressure Signal Circuit is open, it can cause the Dodge P0846 Code to be triggered. In this situation, it is important to check the circuit wiring for any breaks or faults. If any issues are found, they should be repaired as soon as possible to ensure that the transmission system is working correctly.
(T47) 2/4 Pressure Signal Circuit Shorted to Ground
The Dodge P0846 Code can also be triggered if the (T47) 2/4 Pressure Signal Circuit is shorted to ground. When this happens, it is important to check the circuit wiring for any shorts to the ground. If any issues are found, they should be repaired as soon as possible to ensure that the transmission system is working correctly.
(T47) 2/4 Pressure Signal Circuit Shorted to Voltage
The Dodge P0846 Code can also be triggered if the (T47) 2/4 Pressure Signal Circuit is shorted to voltage. When this happens, it is important to check the circuit wiring for any shorts to voltage. If any issues are found, they should be repaired as soon as possible to ensure that the transmission system is working correctly.
Transmission Solenoid/Pressure Switch Assembly
If the transmission solenoid or pressure switch assembly is faulty or damaged, the Dodge P0846 Code can be triggered. To repair this issue, it is important to replace the transmission solenoid/pressure switch assembly. It is important to replace the assembly with a new one that is compatible with the vehicle.
Powertrain Control Module (PCM)
Finally, the Dodge P0846 Code can be triggered if there is an issue with the powertrain control module. In this situation, it is important to replace the powertrain control module. It is important to replace the module with a new one that is compatible with the vehicle.
Conclusion: Repairing the Dodge P0846 Code is Important
The Dodge P0846 Code can cause significant damage to the transmission system if left unresolved. To ensure that the transmission system is working correctly, it is important to identify and repair any issues that might be causing the Dodge P0846 Code. Common causes of the code can include a bad transmission solenoid or pressure switch assembly, a faulty powertrain control module, or various other related transmission control system power input trouble codes. Taking the right steps to repair the issue can help ensure that the transmission system is working properly and prevent further damage to the vehicle. The Dodge P0846 Code should not be ignored as it can lead to costly repairs if not resolved in a timely manner.
