Intermediate Shaft Speed Sensor B Circuit Intermittent

Where it lives

For P2748, the sensor sits on the circuit this code reports. The description of P2748 reports a fault at the sensor.

Check these first

• An intermittent open in the intermediate shaft speed sensor B circuit
• A loose or corroded intermediate shaft speed sensor B connector
• A failing intermediate shaft speed sensor B
• Chafed intermediate shaft speed sensor B wiring

What to do next

1. Read intermediate shaft speed sensor B on a scan tool
2. Wiggle test the intermediate shaft speed sensor B harness while watching data
3. Test the intermediate shaft speed sensor B circuit for intermittent open and short faults
4. Check the intermediate shaft speed sensor B connector pins
5. Replace intermediate shaft speed sensor B if the fault follows the harness
6. Clear the code and retest
