Guide To P0877 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0877 can be explained as Transmission Fluid Pressure Sensor/Switch "D" Circuit Low. If the pressure of the transmission fluid would not be as per the desirable range, then P0877 error code would start triggering up. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

We believe that an investment in knowledge pays the best interest. So why not learn more about the P0877 error code? The mechanical transmission pressures are converted into an electrical signal by the TFPS for the powertrain control module or transmission control module. Generally, the other controllers utilizing the vehicle's data communication bus would then be informed by the PCM/TCM.

What causes this problem with the Transmission Fluid Pressure Sensor/Switch "D" Circuit Low?

• There can be less transmission fluid level
• Faulty transmission
• Some issues related to the engine overheating
• Sliding transmission
• Unusable transmission temperature sensor
• Imperfect transmission high pressure pump
• Defective transmission fluid pressure sensor

Here are some steps which you should follow in order to diagnose this fault code:

First of all, you should research the technical service bulletins for the specific vehicle by year, model and transmission before you start with the troubleshooting process for any malfunction. You can start the process of diagnosis with the power associated trouble code or with a number of code diagnosis. This might be the reason why P0877 error code is appearing. After that the transmission fluid pressure sensor/switch should be situated on your specific automobile. The TFPS is generally found attached to the side of the valve body inside the transmission. It can also be situated on the side of the transmission case. Now once it has been located, then the connector as well as wiring should be visually located. You can always search for the wires which are bare, burned spots as well as plastic which has been melted. The connector should be pulled apart and the terminals which are inside the connector should be inspected properly. You must check if they are appearing burnt and if there is a green tint, then it would indicate that there is corrosion. This can happen if they are attached outside the case of the transmission. An electrical contact cleaner as well as plastic bristle brush should be used to clean the terminals as per the requirement. It should be allowed to dry properly and then electrical grease should be applied at the places where the terminals are in contact. By using a scan tool, all the diagnostic trouble codes should be cleared up from the memory. Then check if the P0877 code has returned or not. If you find out that it is not appearing again, then it would mean that there were some defects in the connections. Now if this error code returns, then you should definitely test the TFPS sensor as well as the related circuits. The electrical connector at the TFPS sensor should be disconnected with the key off. A digital voltmeter should be connected to the ground or low reference terminal at the TFPS sensor wiring harness connector. Then a read lead should be connected to the digital voltmeter. Then the key should be turned on and then engine should be off. You should carefully check the manufacturer's specifications. The reading of the voltmeter should be either 12 volts or 5 volts. You can always wiggle the connections to check if they are changing or not. Now if the voltage is not correct, then the ground wire should be repaired properly. Make sure to restore the PCM/TCM. 

Common Mistakes When Diagnosing the P0877 Code

• The car mechanic might make a mistake of assuming a less fluid situation as well as leak, when in reality the transmission internals might be damaged.
• One another thing is that when a vehicle is being operated for a small period of time with less fluid, then it does not always mean that there is a need of rebuild.
