Frequently Asked Questions about P1900 2011 Ford Fusion Code
1. What does the OBDII code P1900 mean on a 2011 Ford Fusion?
The P1900 code indicates an intermittent malfunction in the Output Shaft Speed (OSS) sensor circuit, which monitors the rotational speed of the transmission output shaft.
2. What are the symptoms of a P1900 code in a 2011 Ford Fusion?
Common symptoms include erratic shifting, transmission slipping, reduced performance, or the vehicle entering limp mode. The Check Engine Light may also illuminate.
3. What causes the P1900 code to appear on a Ford Fusion?
Possible causes include a faulty OSS sensor, damaged or corroded wiring, loose or disconnected connectors, or issues within the transmission control module (TCM).
4. Can I drive my 2011 Ford Fusion with a P1900 code?
While it may be possible to drive the vehicle, it is not recommended as the transmission could behave unpredictably, potentially causing further damage or unsafe driving conditions.
5. How do I diagnose the P1900 code on my Ford Fusion?
Start by checking the OSS sensor and its wiring for damage or corrosion. Use a scan tool to monitor OSS sensor data and verify if the signal is intermittent or missing.
6. How do I fix the P1900 code on a 2011 Ford Fusion?
Repairs may include replacing the OSS sensor, repairing or replacing damaged wiring/connectors, or reprogramming or replacing the TCM if necessary.
7. Where is the Output Shaft Speed (OSS) sensor located on a 2011 Ford Fusion?
The OSS sensor is typically located on the transmission near the output shaft. Refer to the vehicle’s service manual for its exact location.
8. How much does it cost to repair a P1900 code on a Ford Fusion?
Costs can vary, but replacing the OSS sensor typically ranges from $150 to $300, including parts and labor. Wiring repairs or TCM replacement may increase the cost.
9. Can a dirty or low transmission fluid level cause a P1900 code?
While not a direct cause, dirty or low transmission fluid can lead to poor transmission performance, which could exacerbate sensor-related issues.
10. Do I need to clear the P1900 code after repairs?
