Cost Of Fixing p0877 Fault Code
The repair for fault code P0877 typically involves diagnosing and fixing issues with the transmission fluid pressure.
The cost to diagnose and fix OBD code P0877 typically ranges from $75 to $150, with an estimated repair time of 1. 0 hour.
Costs depend on labor rates, shop fees, and the complexity of the issue.
Details of the p0877 OBD Code
Code P0877 relates to an issue with the transmission fluid pressure.
OBD code P0877 means a transmission fluid pressure (TFP) sensor C circuit low.
This code is triggered by the ECM (Engine Control Module) when it detects a low voltage signal from the transmission fluid pressure sensor C.
The TFP sensor C is typically located inside the transmission and is responsible for monitoring the fluid pressure within the transmission.
When the voltage signal from this sensor falls below a specified threshold, the ECM sets code P0877 to indicate a potential issue with the transmission fluid pressure sensor circuit.
Mechanic’s Tech Notes
This section provides detailed information on diagnosing and fixing code P0877.
To diagnose and fix OBDII code P0877, start by checking the transmission control module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.
This thorough inspection can help identify and address any issues causing the P0877 code.
