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.

What does transmission fluid pressure low mean?

If the fluid is low, it should be assumed that there is a leak in the system , and the mechanic should begin searching for where the leak is coming from. ... If the transmission fluid level is normal, the mechanic should check to see if the transmission temperature sensors are faulty.

What does code po700 mean?

P0700 is set when the PCM detects a malfunction in the transmission control system. This malfunction causes the vehicle to set a Check Engine Light and trigger a failsafe mode. Once the failsafe mode is set it will remain until the fault is repaired or normal operation is detected.

What is pressure control solenoid?

The transmission pressure control solenoid controls the fluid pressure to the internal friction plate clutches or drum bands . A bad or failing transmission pressure control solenoid can cause slipping, which can result in the transmission overheating.

How do you check transmission fluid level?

Pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check the fluid level— how high the fluid comes up on the dipstick —against the “full” and “low” or “fill” marks on the dipstick. The color of transmission fluid can tell you a lot about the health of your car’s transmission.
