Details of the c164a OBD Code
Code C164A relates to a fault in the steering angle sensor module.
OBD code C164A means Steering Angle Sensor 1 Circuit Low.
This code is triggered by the Electronic Steering Control Module (ESCM) when it detects a low voltage signal from the steering angle sensor.
The steering angle sensor is part of the vehicle’s stability control system and is responsible for measuring the steering wheel angle and rate of turn.
When the voltage signal from the sensor falls below a specified threshold, the ESCM sets code C164A to indicate a circuit low condition.
Mechanic’s Tech Notes
Code C164A indicates a fault in the steering angle sensor module on the vehicle.
OBDII code C164A typically indicates a problem with the Transmission Control Module (TCM).
To diagnose this, you can start by checking the TCM power and ground using a multimeter to ensure proper voltage levels.
Next, use a scan tool to communicate with the TCM over the Controller Area Network (CAN) network to verify its responsiveness.
If the TCM does not respond, reprogramming or reflashing it may be necessary.
Additionally, visually inspect the wiring harness and connectors for any damage, and check the connector pins for signs of corrosion, bending, or breakage.
This thorough inspection can help pinpoint the root cause of the issue.
