Details of the c116a OBD Code
Code C116A relates to a fault in the steering angle sensor circuit.
OBD code C116A means Steering Angle Sensor Signal Malfunction.
This code is triggered by the Electronic Stability Control (ESC) module when it detects a fault in the signal coming from the steering angle sensor.
The steering angle sensor is responsible for providing data on the steering wheel position and rate of turn, which is crucial for the ESC system to function properly and help maintain vehicle stability during maneuvers.
Mechanic’s Tech Notes
Code C116A relates to a fault in the steering angle sensor circuit.
OBDII code C116A relates to a communication error between the transmission control module (TCM) and the engine control module (ECM).
To diagnose this, check TCM power and ground using a multimeter.
Use a scan tool to confirm if the TCM communicates over the Controller Area Network (CAN) network.
Inspect the wiring harness and connectors for any 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.
