What is code P0845?
OBD-II Code P0845 is defined as a Transmission Fluid Pressure Sensor/Switch “B” Circuit. The Transmission Fluid Pressure Switch allows the engine’s control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving.
How do I fix code p0848?
How to Fix
- Replacement of transmission fluid sensor.
- Replacement of transmission fluid sensor control solenoid.
- Replacement or flushing of transmission fluid.
- Repair blocked or damaged hoses.
How to test the p0845 transmission fluid pressure sensor?
If the P0845 code does return, we will need to test the TFPS sensor and its associated circuits. With the Key Off, disconnect the electrical connector at the TFPS sensor. Connect a Digital Voltmeter (DVOM) black lead to the ground or low reference terminal at the TFPS sensor wiring harness connector.
What are the symptoms of a p0845 engine code?
Symptoms of a P0845 engine code may include: Vehicle starts off in 2nd or 3rd gear (limp in mode) Typically the causes for this code to set are: Open in the signal circuit to the TFPS sensor – possible Short to voltage in the signal circuit to the TFPS sensor – possible Short to ground in the signal circuit to the TFPS sensor – possible
What to do if your transmission fluid pressure sensor is not working?
Use electrical contact cleaner and a plastic bristle brush if cleaning of the terminals is needed. Let dry and apply electrical grease where the terminals contact. If you have a scan tool, clear the diagnostic trouble codes from memory, and see if P0845 code returns. If it does not, then the connections were most likely your problem.
What does transmission fluid pressure sensor ” B ” circuit mean?
