Details of the c1400 OBD Code
Code C1400 relates to an issue with the vehicle’s vehicle speed sensor circuit.
OBD code C1400 indicates an issue with the vehicle’s vehicle speed sensor circuit.
This code is triggered by the Electronic Control Module (ECM) when it detects a problem with the vehicle speed sensor or its circuitry.
The vehicle speed sensor is responsible for monitoring the speed of the vehicle and providing this information to the ECM for various vehicle systems to function properly, such as the speedometer, cruise control, and transmission control module.
When the ECM detects a fault in the vehicle speed sensor circuit, it will trigger the C1400 fault code.
Mechanic’s Tech Notes
Code C1400 relates to an issue with the vehicle’s vehicle speed sensor circuit.
OBDII code C1400 relates to an issue with the vehicle’s Traction Control Module (TCM).
