Possible triggers for fault code C1079 include issues with the brake pedal position sensor.
- C1079 can be caused by Steering Angle Sensor Calibration Incomplete.
- A Faulty Steering Angle Sensor.
- An open or shorted Steering Angle Sensor harness.
- A poor electrical connection in the Steering Angle Sensor circuit.
- A Faulty AntiLock Brake System (ABS) / Electronic Stability Program (ESP®) Control Module.
Fixing Error Code c1079 Step By Step
To resolve fault code C1079, inspect the ABS pump motor circuit for potential issues.
- To fix OBDII code C1079, first, review the possible causes related to this code.
- Visually inspect the wiring harness and connectors associated with the ABS system.
- Check for any damaged components and ensure the connector pins are not broken, bent, pushed out, or corroded.
- If no issues are found during the visual inspection, proceed to perform a diagnostic scan tool test to pinpoint the exact cause of the fault.
- Based on the scan results, repair or replace any faulty ABS system components such as wheel speed sensors, control modules, or wiring as necessary.
- Finally, clear the fault code from the vehicle’s computer using a diagnostic scan tool to complete the repair process.
Cost Of Fixing c1079 Fault Code
Diagnosing and repairing fault code c1079 may involve inspecting and testing the vehicle’s brake pedal position sensor.
The cost to diagnose and fix OBD code C1079 depends on the estimated 1. 0hour repair time.
Labor rates range from $75 to $150 per hour, so the total cost could be between $75 and $150. Factors like shop rates and complexity of the repair can influence the final cost.
Details of the c1079 OBD Code
Code C1079 indicates a malfunction in the regenerative braking system of a hybrid vehicle.
OBD code C1079 means Park Brake Actuator Motor Current Range/Performance.
This code is triggered by the Electronic Parking Brake (EPB) module when it detects that the current being drawn by the actuator motor is outside of the expected range or if the motor is not performing as expected during activation or deactivation of the parking brake system.
The EPB system uses an electric motor to apply and release the parking brake instead of a traditional mechanical system.
When the EPB module detects issues with the actuator motor’s current draw, it sets the C1079 fault code to indicate a potential problem with the motor or its control circuit.
Mechanic’s Tech Notes
Code C1079 indicates a fault with the regenerative braking system on hybrid vehicles.
OBDII code C1079 typically indicates a fault with the Transmission Control Module (TCM).
To diagnose, check TCM power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
Visually inspect wiring harnesses and connectors for damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
If no visible issues are found, consider reprogramming or reflashing the TCM.
This process can often resolve communication errors and restore proper TCM function.
FAQ
OBD code C1079 indicates an issue with the Steering Angle Sensor system. Check sensor calibration, wiring, connectors, and ABS/ESP module for faults.
Common symptoms of OBD code C1079 include ABS warning light on, engine light on, caused by incomplete steering angle sensor calibration or faulty components. Fix involves inspecting wiring and connectors.
Diagnose and repair OBD code C1079 by checking steering angle sensor calibration, sensor condition, wiring integrity, and ABS/ESP module. Inspect and repair any damaged components or connections.

Wrap Up
If your ABS warning light is on and you see OBDII code c1079, it may indicate a fault with the brake pedal switch, brake fluid level sensor, or related wiring issues.
These components are crucial for proper ABS system operation.
To address OBDII code c1079, start by checking the brake pedal switch and brake fluid level sensor for proper operation and wiring integrity.
Inspect the wiring harness for any signs of damage, corrosion, or loose connections that could be affecting the ABS system’s ability to monitor brake pedal position and fluid level accurately.
