C200D Mercury Code - Motor Rotation Angle Sensor

Quick Answer

The Power Steering Control Module (PSCM) monitors various inputs and outputs of the Electric Power-Assisted Steering (EPAS) system in order to keep the system operating at peak capacity. Common causes include Faulty Motor Rotation Angle Sensor, Motor Rotation Angle Sensor harness is open or shorted, Motor Rotation Angle Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C200D Mercury Description

The Power Steering Control Module (PSCM) monitors various inputs and outputs of the Electric Power-Assisted Steering (EPAS) system in order to keep the system operating at peak capacity. Information provided by sensors (steering torque, vehicle speed, vehicle travel distance, etc.) are all compared to programmed and learned information. Likewise, outputs like the motor and steering rack (travel) are tested against programmed and learned information. This test generates a RVC for a new PSCM when directed to do so from pinpoint test. A RVC is required to order a new PSCM and to document billing for payment.

Frequently Asked Questions about C200D Mercury Code

1. What does the OBDII code C200D mean on a Mercury vehicle?

The C200D code refers to an issue with the Motor Rotation Angle Sensor, which monitors the position or angle of a motor, typically related to systems like power steering or advanced braking.

2. What are the common symptoms of a C200D code?

Symptoms may include warning lights on the dashboard (such as ABS or traction control), difficulty with steering, or erratic operation of affected systems like electronic power steering.

3. What causes the C200D Motor Rotation Angle Sensor code?

The code can be triggered by a faulty motor rotation angle sensor, damaged wiring or connectors, or an issue with the control module receiving improper sensor data.

4. Can I drive my Mercury with a C200D code?

While driving may still be possible, it could compromise safety features like power steering or stability control, so itâ€™s best to address the issue promptly.

5. How is the C200D code diagnosed?

A technician will use a diagnostic scanner to confirm the code, inspect the sensor, wiring, and connections, and may perform tests to verify sensor functionality.

6. How do you fix a C200D code on a Mercury?

Repairs may include replacing the faulty motor rotation angle sensor, repairing damaged wiring or connectors, or reprogramming/updating the control module.

7. How much does it cost to fix the C200D code?

Repair costs vary but typically range from $150 to $500, depending on whether the sensor needs replacing or if there are wiring issues.

8. Can a faulty Motor Rotation Angle Sensor cause other problems?

Yes, it can lead to impaired functionality in systems relying on motor position data, such as power steering, ABS, or stability control systems.

9. Is the C200D code related to other OBDII codes?

It can sometimes appear with codes related to ABS, traction control, or electronic power steering, indicating a broader system issue.

10. How can I prevent the C200D code from reoccurring?

Regular vehicle maintenance, addressing wiring issues promptly, and ensuring sensors are not exposed to excessive dirt, moisture, or damage can help prevent this code.
