The transmission fluid pressure sensor measures the pressure of the fluid going through the transmission and sends this data to the transmission control module (TCM). OBD P0876 is a generic trouble code that the vehicle’s computer could log if there’s a problem with the transmission fluid sensor.
Diagnostic trouble code (DTC) P0876 stands for “Transmission Fluid Pressure Sensor/Switch D Circuit Range Performance.”
The transmission fluid pressure sensor/switch (TFPS) is usually found inside the transmission beside the valve body. On some vehicles, it is screwed into the side of the transmission case/body.
The TFPS converts transmission pressure into electrical signals for the TCM or the powertrain control module (PCM). The PCM uses the voltage signal when a shift occurs or to determine the right amount of transmission operating pressure.
Once the PCM or TCM detects that the input voltage does not match the normal voltage reading that’s set in its memory, it’ll trigger the P0876 code. The code can also be logged due to a mechanical fault inside the transmission.
Note: The definition of code P0876 can differ according to the vehicle manufacturer. Check the appropriate repair manual or repair database for the exact code definition.
DTC P0876 can occur in different vehicles. This does not, however, imply that there is a universal solution to this problem. Keep in mind that vehicle structures differ depending on the manufacturer.
If you’re not familiar with vehicle repair, take your car to a mechanic for a proper diagnosis. Otherwise, you can diagnose the trouble code yourself. Here’s a video that could give you an idea of what the process might involve.
Clearing trouble codes can be tricky. If you don’t have the right tools or know-how to get the job done, we recommend letting an expert resolve the trouble code.
But if you’re an experienced DIYer with in-depth knowledge of car repair, you can do the job yourself. Make sure you refer to vehicle-specific repair information before you get started. Repair manuals like those from Chilton or a subscription to an online repair database can give you information on the correct diagnostic and repair procedure to clear code P0876.
