Code P1715 Description
The P1715 diagnostic trouble code (DTC) refers to the Input Speed Sensor Primary Speed Sensor in the vehicle's transmission system. This code indicates that there is a malfunction or fault detected in the input speed sensor, which is crucial for the proper operation of the transmission. The input speed sensor is responsible for monitoring the speed of the transmission input shaft and sending this information to the engine control module (ECM) or transmission control module (TCM).
Common Causes of P1715
- Faulty input speed sensor
- Damaged wiring or connectors in the sensor circuit
- Low transmission fluid levels or contaminated fluid
- Issues with the ECM or TCM
- Mechanical issues within the transmission system
Symptoms of P1715
- Erratic shifting patterns
- Harsh shifting or jerking when changing gears
- Delayed engagement when shifting into gear
- Transmission slipping
- Illumination of the Check Engine Light
How to Fix P1715
- Diagnose the issue by using a scan tool to retrieve the DTC and inspect the input speed sensor for any visible damage or faults.
- Check the wiring and connectors in the sensor circuit for any signs of damage or corrosion. Repair or replace as necessary.
- Test the input speed sensor using a multimeter to ensure that it is functioning properly. Replace the sensor if it is faulty.
- Inspect the transmission fluid level and condition. Top off or replace the fluid if necessary.
- Clear the DTC and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P1715
The cost of repairing the Input Speed Sensor Primary Speed Sensor issue can vary depending on the make and model of the vehicle, the location of the repair shop, and the extent of the damage.
