P2747 Fault Code

Intermediate Shaft Speed Sensor B Circuit No Signal

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2747 code indicates that there is a malfunction in the 'B' circuit of the Intermediate Shaft Speed Sensor. This sensor is critical for monitoring the speed of the intermediate shaft within the transmission, which helps the engine control module (ECM) determine proper gear shifting and overall vehicle performance.

What are the symptoms of the P2747 code?

• Transmission may exhibit erratic shifting behavior
• Check Engine Light (CEL) will be illuminated
• Reduced acceleration and power delivery
• Possible engine stalling or hesitation during gear changes
• Unusual noises from the transmission

What causes the P2747 code?

Several factors can lead to the P2747 code:

• Faulty Intermediate Shaft Speed Sensor
• Damaged wiring or connections within the sensor circuit
• Issues with the Engine Control Module (ECM)
• Poor electrical connections due to corrosion or damage
• Internal transmission problems affecting the sensor's functionality

How to fix P2747?

• Inspect and clean the connections to the Intermediate Shaft Speed Sensor.
• Test the sensor for proper functionality and replace if necessary.
• Check the wiring for any signs of damage or corrosion and repair as needed.
• If problems persist, consider scanning for additional trouble codes to diagnose related issues more accurately.
