Understanding the Dodge Code P0846-2C can be a complex task, but it is a crucial part of diagnosing and repairing automotive transmission problems. This code is a Pressure Switch Rationality (PSR) code, which is set when the 2C pressure switch reads open or closed at the wrong time in a given gear. It is important to determine the cause of this code in order to successfully repair the issue, as the causes can range from low line pressure to a faulty transmission solenoid/TRS assembly. It is essential to understand the potential causes and their solutions in order to effectively diagnose and repair the issue.
Causes and Solutions for Dodge Code P0846-2C
| Cause | Solution |
|---|---|
| RELATED TCM POWER INPUT DTCS PRESENT | Check the wiring and connectors to the TCM power input circuits. |
| (T147) 2C PRESSURE SWITCH SENSE CIRCUIT OPEN | Test the circuit and repair the open. |
| (T147) 2C PRESSURE SWITCH SENSE CIRCUIT SHORTED TO GROUND | Inspect and repair the wiring and connectors as required. |
| (T147) 2C PRESSURE SWITCH SENSE CIRCUIT SHORTED TO OTHER CIRCUITS | Check the wiring and connectors for shorts to other circuits. |
| EXCESSIVE FLUID LEAKAGE IN 2C CLUTCH CIRCUIT | Inspect the clutch circuit for fluid leakage and repair as necessary. |
When the Dodge Code P0846-2C appears, one of the causes may be related to the power input circuits to the TCM. The power input circuits are responsible for supplying power to the transmission control module, and if they are not working correctly, the code will be set. The first step in resolving this issue is to inspect the wiring and connectors for the power input circuits and repair any faults or damage found.
(T147) 2C PRESSURE SWITCH SENSE CIRCUIT OPEN
Another cause of the Dodge Code P0846-2C is an open circuit in the 2C pressure switch sense circuit. This occurs when the circuit is not properly connected, or when it has failed due to a defect or damage. In order to repair this issue, the circuit must be tested and any open faults must be repaired.
(T147) 2C PRESSURE SWITCH SENSE CIRCUIT SHORTED TO GROUND
If the Dodge Code P0846-2C is set due to a shorted circuit in the 2C pressure switch sense circuit, it means that the wiring and connectors have been damaged and must be inspected. If any faults are found, they must be repaired in order to resolve the issue.
(T147) 2C PRESSURE SWITCH SENSE CIRCUIT SHORTED TO OTHER CIRCUITS
When the Dodge Code P0846-2C is set due to a shorted circuit in the 2C pressure switch sense circuit, it may be because the wiring and connectors are damaged and have caused a short to other circuits. To repair this issue, the wiring and connectors must be checked for any shorts to other circuits and repaired as necessary.
EXCESSIVE FLUID LEAKAGE IN 2C CLUTCH CIRCUIT
The last possible cause of the Dodge Code P0846-2C is excessive fluid leakage in the 2C clutch circuit. This can be caused by a variety of issues, such as worn or damaged seals, or a faulty transmission solenoid/TRS assembly. If this is the cause of the issue, the clutch circuit must be inspected for fluid leakage and the necessary repairs must be made.
Conclusion
Understanding the Dodge Code P0846-2C is essential in order to diagnose and repair automotive transmission problems. There are several potential causes for this code, and it is important to determine the cause in order to successfully repair the issue. The possible causes range from low line pressure to a faulty transmission solenoid/TRS assembly, and the solutions range from inspecting and repairing wiring and connectors to inspecting the clutch circuit for fluid leakage. By understanding the potential causes, symptoms, and solutions for the Dodge Code P0846-2C, automotive technicians can successfully diagnose and repair the issue.
