Details of the Hummer p0715 OBD Code

Fault code P0715 in a Hummer indicates a problem with the input speed sensor circuit.

OBD code P0715 for a Hummer indicates a malfunction in the input speed sensor circuit.

This code is triggered by the ECM when it detects an issue with the input speed sensor signal.

The input speed sensor is responsible for monitoring the speed of the transmission input shaft.

When the sensor fails or sends an erratic signal, the ECM sets code P0715. This code is commonly associated with transmission shifting issues and may cause the transmission to go into a failsafe mode to prevent further damage.

Mechanic’s Tech Notes

For Hummer P0715, the input speed sensor circuit malfunction is likely causing transmission issues.

OBDII code P0715 in a Hummer indicates a malfunction in the input speed sensor circuit.

To diagnose, use a multimeter to check the input speed sensor’s resistance and voltage.

Ensure the sensor is receiving proper power and ground.

Use a scan tool to monitor the sensor’s data and confirm its operation.

Inspect the wiring harness and connectors for any damage, corrosion, or loose connections.

If no visible issues are found, the input speed sensor itself may need replacement.

Reflashing the TCM software could also be necessary to resolve the fault.
