20. FAQs About VCDS and Motor Position Sensor Errors

1. What Does “VCDS Sensor for Motor Position Implausible” Mean?

The error code “VCDS sensor for motor position implausible” indicates that the signal from the motor position sensor in your vehicle’s power steering system is unreliable or makes no sense to the control unit. This fault suggests a discrepancy between the actual position of the steering motor and what the sensor is reporting. This error typically shows up when using VCDS (VAG-COM Diagnostic System), a popular diagnostic tool for Volkswagen Audi Group (VAG) vehicles.

The “implausible” aspect means the value falls outside expected parameters. This can lead to a range of symptoms, from reduced power steering assistance to complete steering failure, posing a significant safety risk. In simple terms, the car’s computer is saying, “The information I’m getting from the steering sensor doesn’t seem right, and I can’t trust it.” This could be because the sensor is faulty, the wiring is damaged, or there’s a deeper issue within the steering system itself.

2. Common Causes of the Error

Several factors can trigger the “VCDS sensor for motor position implausible” error. Identifying these causes is crucial for effective diagnosis and repair:

• Faulty Motor Position Sensor: The sensor itself may be defective, providing inaccurate readings.
• Wiring Issues: Damaged, corroded, or loose wiring can disrupt the signal between the sensor and the control unit.
• Power Steering Control Module Failure: The control module (ECU) might be malfunctioning, misinterpreting the sensor’s data.
• Low Voltage: Insufficient voltage to the sensor or control module can cause erratic behavior.
• Software Glitches: Corrupted or outdated software in the control module can lead to misinterpretations of sensor data.
• Mechanical Issues: Problems within the power steering motor or rack can indirectly affect the sensor’s readings.
• Environmental Factors: Extreme temperatures or moisture can sometimes affect sensor performance.

Addressing these potential causes requires systematic troubleshooting, often involving sensor testing, wiring checks, and ECU diagnostics.
