This image shows the sensor's main body, the electrical connector at the top with two pins visible, and the metal mounting tab extending from the side. A red O-ring is visible on the lower part of the sensor body, indicating a sealing point.

The sensor is designed to provide precise readings to the vehicle's Powertrain Control Module (PCM) or Transmission Control Module (TCM), which uses this data for accurate gear shifting and other transmission functions.

4. การติดตั้ง

The installation of an automatic transmission speed sensor typically involves the following steps. บันทึก: Specific procedures may vary by vehicle make and model. Always consult your vehicle's service manual for precise instructions.

1. การตระเตรียม: Park the vehicle on a level surface, engage the parking brake, and turn off the engine. Disconnect the negative terminal of the battery. Allow the transmission to cool if it has been recently operated.
2. ค้นหาเซ็นเซอร์: Identify the location of the existing transmission speed sensor. This is often found on the transmission housing, typically near the output shaft or differential.
3. ถอดขั้วต่อไฟฟ้า: Carefully disconnect the electrical connector from the old sensor. Press any release tabs or slide locks before pulling the connector.
4. ถอดเซ็นเซอร์เก่าออก: Use an appropriate wrench or socket to loosen and remove the bolt or fastener securing the sensor. Gently pull the old sensor straight out from its mounting bore. Be prepared for a small amount of transmission fluid to leak out.
5. ตรวจสอบพื้นที่ติดตั้ง: Clean the sensor mounting bore and inspect it for any debris or damage. Ensure the new sensor's O-ring (if applicable) is properly seated and lubricated with a small amount of clean transmission fluid.
6. ติดตั้งเซ็นเซอร์ใหม่: Insert the new Generic 917-620 sensor into the mounting bore. Ensure it is fully seated. Secure it with the retaining bolt or fastener. Tighten to the vehicle manufacturer's specified torque. อย่าขันแน่นจนเกินไป
7. เชื่อมต่อขั้วต่อไฟฟ้าใหม่: ต่อขั้วต่อไฟฟ้าเข้ากับเซ็นเซอร์ตัวใหม่ ตรวจสอบให้แน่ใจว่าล็อคเข้าที่อย่างแน่นหนา
8. ขั้นตอนสุดท้าย: Reconnect the negative battery terminal. Start the vehicle and check for proper operation and any diagnostic trouble codes (DTCs). A test drive may be necessary to confirm functionality.

5. การดำเนินการ

Once installed, the 917-620 Automatic Transmission Speed Sensor operates by generating an electrical signal proportional to the rotational speed of the transmission's output shaft. This signal is sent to the vehicle's control module.

The control module uses this speed data for various functions, including:

• Determining optimal shift points for the automatic transmission.
• Providing accurate vehicle speed readings to the speedometer.
• Assisting in the operation of cruise control and anti-lock braking systems (ABS).
• Detecting transmission slippage or other anomalies.

A properly functioning speed sensor is essential for the smooth and efficient operation of your vehicle's automatic transmission.

6. การบำรุงรักษา

The Generic 917-620 Automatic Transmission Speed Sensor is a sealed, maintenance-free component. No routine maintenance is required for the sensor itself.

However, it is advisable to:

• Ensure the electrical connector remains clean and free of corrosion.
• Periodically check for any signs of physical damage to the sensor or its wiring during routine vehicle inspections.
• Maintain proper transmission fluid levels and quality as per your vehicle manufacturer's recommendations, as this can indirectly affect sensor longevity.

7 การแก้ไขปัญหา

If you suspect an issue with your transmission speed sensor, consider the following common symptoms and potential solutions:

For complex issues or persistent problems, it is recommended to seek assistance from a certified automotive technician or a Dorman service center.
