The factors influencing the cost of diagnosing and fixing the automobile fault code p0845 include the estimated repair time of 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.
These factors contribute to the overall cost of resolving the p0845 fault code.
P0845: Transmission Fluid Pressure Sensor/Switch B Circuit
The P0845 fault code is related to the transmission fluid pressure sensorswitch ‘B’ circuit.
When this error occurs, it means there is a problem with the 2-4 pressure switch in the transmission control module (TCM). To identify the issue, the TCM briefly activates the pressure in the 2-4 clutch circuit and checks if the pressure switch closes.
If the switch fails to close during the first test, it is tested again. If the switch still doesn’t close on the second test, the P0845 fault code is triggered.
When this fault code is detected, the malfunction indicator lamp (MIL) will illuminate, and the transmission system will default to limp-in mode.
This mode is a safety measure that allows you to drive the vehicle at reduced speed and power to prevent further damage. It is important to address the P0845 fault code promptly to avoid potential transmission issues and restore the normal functioning of your vehicle.
