Code P17CE 2019 Chevrolet Silverado Description
The P17CE code indicates that the Input Speed Sensor (ISS) is reporting a direction of rotation that is not plausible to the Transmission Control Module (TCM). This sensor plays a crucial role in the transmission system by monitoring the speed of the primary pulley and providing real-time data to the TCM. The ISS is a Hall-effect sensor that mounts to the control valve assembly and is positioned to read the machined teeth of the clutch housing. When the vehicle is in motion, the sensor generates a frequency signal that reflects the rotational speed of the clutch housing. This information is vital for the TCM to manage various transmission functions, including line pressure control, shift timing, and Torque Converter Clutch (TCC) engagement.
Common Causes of P17CE 2019 Chevrolet Silverado
- Faulty Transmission Input Speed Sensor
- Open or shorted wiring in the Transmission Input Speed Sensor harness
- Poor electrical connection in the Transmission Input Speed Sensor circuit
- Faulty Control Solenoid Valve Assembly
- Contamination or debris affecting the sensor's operation
Symptoms of P17CE 2019 Chevrolet Silverado
- Engine Light ON (or Service Engine Soon Warning Light)
- Erratic or harsh shifting during acceleration
- Decreased fuel efficiency
- Transmission overheating or slipping
- Potential no-start condition
How to Fix P17CE 2019 Chevrolet Silverado
- Perform a visual inspection of the Input Speed Sensor and its wiring harness for signs of damage or wear.
- Test the Input Speed Sensor using a multimeter to check for proper voltage and signal output.
- If the sensor is faulty, replace the Input Speed Sensor with a new, OEM-quality part.
- Inspect and repair any damaged wiring or poor connections in the sensor circuit.
- Clear the diagnostic trouble codes and perform a road test to ensure the issue is resolved and the transmission operates smoothly.
Cost to Fix P17CE 2019 Chevrolet Silverado
The cost to diagnose and repair the P17CE code typically ranges from $150 to $400, depending on the specific issue and whether parts need to be replaced. The Input Speed Sensor itself can cost between $50 and $150, while labor charges can vary significantly, with most shops charging between $80 and $150 per hour. Dealerships may charge higher rates, while independent shops may offer lower prices.
