P17CE 2019 GMC Sierra Code - Input Speed Sensor Direction Not Plausible
Quick Answer
The P17CE code indicates that there is an issue with the Input Speed Sensor (ISS) in a GMC vehicle, specifically relating to its ability to provide accurate readings of the primary pulley revolution speed. Common causes include Faulty Transmission Input Speed Sensor, Transmission Input Speed Sensor harness is open or shorted, Transmission Input Speed Sensor circuit has poor electrical connections. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P17CE 2019 GMC Sierra Description
The P17CE code indicates that there is an issue with the Input Speed Sensor (ISS) in a GMC vehicle, specifically relating to its ability to provide accurate readings of the primary pulley revolution speed. The ISS, also known as the transmission turbine speed sensor, plays a crucial role in the operation of the vehicle's transmission system. It is a Hall-effect type sensor that is mounted on the control valve upper body assembly and communicates with the Transmission Control Module (TCM) via a wire harness. The sensor is designed to detect the rotational speed of the 1-2-3-4 and 3-5-R clutch housing by measuring the frequency of the magnetic field changes as the teeth on the machined surface pass by the sensor.
Common Causes of P17CE 2019 GMC Sierra
- Faulty Transmission Input Speed Sensor
- Transmission Input Speed Sensor harness is open or shorted
- Transmission Input Speed Sensor circuit has poor electrical connections
- Faulty Control Solenoid Valve Assembly
- Internal transmission issues affecting sensor operation
Symptoms of P17CE 2019 GMC Sierra
- Engine Light ON (or Service Engine Soon Warning Light)
- Erratic or harsh shifting between gears
- Transmission slipping or failing to engage
- Decreased fuel efficiency
- Unusual noises from the transmission during operation
How to Fix P17CE 2019 GMC Sierra
- Perform a diagnostic scan to confirm the P17CE code and check for any related codes.
- Inspect the wiring and connectors associated with the Input Speed Sensor for damage, corrosion, or loose connections.
- Test the Input Speed Sensor using a multimeter to ensure it is functioning within the specified voltage range.
- If the sensor is faulty, replace the Input Speed Sensor with a new, OEM-quality part.
- Clear the diagnostic codes and take the vehicle for a test drive to verify that the issue has been resolved and that the transmission operates smoothly.
Cost to Fix P17CE 2019 GMC Sierra
The cost to diagnose and repair the P17CE code typically ranges from $150 to $400, depending on the specific cause of the issue. Parts for a new Input Speed Sensor generally cost between $50 and $150, while labor can vary significantly based on the shop's hourly rate, which usually falls between $80 and $150 per hour. Dealerships may charge more, while independent shops might offer lower rates. Additional costs may arise if further repairs are needed, such as wiring harness replacements or control solenoid valve assembly repairs.
