Cost Of Fixing c159f Fault Code
Diagnosing and repairing fault code C159F may involve inspecting and testing the vehicle’s ABS module.
The cost to diagnose and fix OBD code C159F depends on the estimated 1. 0hour repair time.
Labor rates usually range from $75 to $150 per hour, so the general cost could be between $75 and $150. The final cost may vary based on shop rates and the complexity of the repair.
Details of the c159f OBD Code
Code C159F relates to a fault in the ABS module communication circuit.
OBD code C159F means Steering Angle Sensor Internal fault.
This code is triggered by the Steering Angle Sensor (SAS) module when it detects an internal fault within the sensor itself.
The SAS is a critical component of the vehicle’s stability control system, providing data on the steering wheel angle to help the system determine the vehicle’s direction and stability.
When this sensor malfunctions, it can affect the accuracy of the stability control system, potentially compromising the vehicle’s handling and safety.
Mechanic’s Tech Notes
Code C159F indicates a fault in the ABS hydraulic pump motor circuit.
OBDII code C159F typically indicates a problem with the transmission control module (TCM).
To diagnose this, you can check the TCM power and ground using a multimeter.
Additionally, use a scan tool to confirm if the TCM communicates properly over the Controller Area Network (CAN) network.
If the wiring harness or connectors appear damaged, inspect them closely for issues like broken, bent, or corroded pins.
Reflashing the TCM software may also be necessary to resolve this issue.
