C1950 – OBD-II DTC

OBD-II DTC C1950 – Accelerometer Sensor Circuit Failure

DTC C1950 meaning

DTC C1950 refers to a fault in the accelerometer sensor circuit, which is part of the vehicle’s stability control system. The accelerometer sensor measures the vehicle’s acceleration forces and helps the vehicle’s control modules determine how to adjust braking and traction control systems. When this code is triggered, it indicates that the signal from the accelerometer sensor is out of range or not functioning properly.

DTC C1950 symptoms

Common symptoms associated with DTC C1950 may include:

• Illuminated check engine light
• Loss of stability control features
• Erratic vehicle handling
• Increased stopping distance
• Unusual acceleration or deceleration behavior

DTC C1950 causes

Several factors can lead to the triggering of DTC C1950, including:

• Faulty accelerometer sensor
• Wiring issues, such as shorts or open circuits
• Corroded or loose connectors
• Faulty control module
• Software issues within the vehicle’s control systems

DTC C1950 seriousness

DTC C1950 is considered a serious issue as it can affect the vehicle’s stability and handling. If left unaddressed, it may lead to unsafe driving conditions, especially in adverse weather or road conditions. It is important to diagnose and repair this issue promptly to ensure the vehicle operates safely.
