Details of the c1881 OBD Code
C1881 indicates a fault with the steering angle sensor on the vehicle.
OBD code C1881 means that a steering angle sensor calibration fault has been detected.
This code is triggered by the steering angle sensor module when it detects an issue with the calibration of the sensor.
The steering angle sensor is a critical component of the vehicle’s stability control system, as it provides information about the steering wheel position and rate of turn to the electronic stability control system.
When the calibration of the sensor is off, it can lead to inaccurate readings and affect the vehicle’s stability control system’s performance.
Mechanic’s Tech Notes
Code C1881 relates to a fault in the steering angle sensor module.
OBDII code C1881 relates to a fault in the transmission control module (TCM) power input signal.
To diagnose this issue, use a voltmeter to check the TCM power and ground circuits for proper voltage levels.
Additionally, utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
If all these checks pass, consider reprogramming or reflashing the TCM as a potential fix.
