The P1900 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates an output shaft speed circuit intermittent malfunction. This code is typically associated with the vehicle's automatic transmission system. The output shaft speed sensor is responsible for monitoring the speed of the output shaft of the transmission. This information is crucial for the transmission control module (TCM) to determine shift points, torque converter lockup, and overall transmission performance.
Common Causes of P1900 2007 Ford Fusion
- Faulty output shaft speed sensor
- Damaged wiring or connectors in the circuit
- Corrosion or poor connections in the sensor circuit
- Issues with the TCM
- Mechanical issues within the transmission itself
Symptoms of P1900 2007 Ford Fusion
- Harsh or delayed shifting
- Transmission slipping
- Limp mode activation
- Loss of power while driving
- Check Engine Light illuminated
