P0715 – Input/Turbine Speed Sensor Circuit Malfunction
Encountering the P0715 code in your Geely? Here is a complete guide to its causes, symptoms, and solutions.
WHAT DOES CODE P0715 MEAN
The P0715 trouble code indicates an issue with the input/turbine speed sensor circuit in your Geely vehicle. This sensor plays a crucial role in monitoring the speed of the turbine, which is essential for the transmission control module (TCM) to determine the optimal gear shift points. When the TCM detects a malfunction in the sensor circuit, it triggers the P0715 error code. Diagnosing the P0715 code is essential to prevent further damage to the transmission and other related components.

DIAGNOSTIC STEPS
To diagnose the P0715 code, start by checking the sensor and its circuit for any signs of damage or corrosion. Verify the sensor’s electrical connections and ensure they are clean and secure. Use a multimeter to measure the sensor’s voltage and resistance, and compare the readings to the factory specifications. Monitor the sensor’s output signal while the engine is running, and verify that the readings change smoothly depending on engine RPM. Consult the Geely workshop manual for specific diagnostic procedures and troubleshooting guides.
HOW TO FIX
Fixing the P0715 code typically involves replacing the faulty input/turbine speed sensor or repairing the wiring issues. In some cases, the TCM may need to be reprogrammed or replaced. It is essential to follow the manufacturer’s instructions and guidelines when replacing or repairing any components. Diagnosing the P0715 code and fixing the underlying issue will help prevent further damage to the transmission and other related components.
IS IT SAFE TO DRIVE WITH THIS CODE
Driving with the P0715 code active can lead to decreased fuel efficiency, erratic shifting, and increased wear on the transmission. In severe cases, it can cause the transmission to overheat, leading to costly repairs. While it may be possible to drive the vehicle with this code, it is not recommended. Fixing the P0715 code as soon as possible will help prevent further damage and ensure the vehicle runs smoothly and efficiently.
ESTIMATED REPAIR COST
The estimated repair cost for the P0715 code can range from $200 to $1,000, depending on the extent of the damage and the labor costs. Replacing the input/turbine speed sensor can cost between $100 to $500, while repairing the wiring issues can add an additional $100 to $300. In some cases, the TCM may need to be replaced, which can add $500 to $1,000 to the total repair cost.
PREVENTIVE MAINTENANCE TIPS
To prevent the P0715 code from occurring, it is essential to maintain the vehicle’s transmission and sensor systems. Regularly check the sensor’s electrical connections and ensure they are clean and secure. Monitor the transmission fluid level and condition, and change it as recommended by the manufacturer. Avoid extreme driving conditions, such as towing or hauling heavy loads, which can put excessive stress on the transmission.
When diagnosing the P0715 code, it is essential to use a high-quality multimeter and follow the manufacturer’s instructions for troubleshooting. In some cases, the sensor may need to be replaced, even if it appears to be functioning properly. A thorough inspection of the sensor and its circuit can help identify any underlying issues and prevent further damage to the transmission.
