Details of the c1170 OBD Code
C1170 indicates a fault with the steering angle sensor on the vehicle.
OBD code C1170 means Steering Angle Sensor Malfunction.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects a fault in the steering angle sensor.
The steering angle sensor is part of the Electronic Stability Control (ESC) system and is responsible for measuring the steering wheel angle and rate of turn.
When the sensor malfunctions, it can affect the ESC system’s ability to function properly, potentially compromising vehicle stability and safety.
Mechanic’s Tech Notes
Code C1170 relates to an issue with the steering angle sensor circuit.
OBDII code C1170 typically indicates a fault with the Electronic Control Unit (ECU) or Transmission Control Module (TCM).
To diagnose, check TCM power and ground using a multimeter.
Use a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
If the TCM does not respond, reprogramming or reflash may be necessary.
Visually inspect wiring harnesses and connectors for damage, and check connector pins for any signs of corrosion, bending, or breakage.
This thorough inspection can help pinpoint the root cause of the issue.
