P0717 2016 Chevrolet Silverado Code - Transmission Input Speed Sensor Circuit No Signal

Quick Answer

The Input Speed Sensor detects the primary pulley revolution speed and sends a signal to the Transmission. Common causes include Faulty Transmission Input Speed Sensor, Transmission Input Speed Sensor harness is open or shorted, Transmission Input Speed Sensor circuit poor electrical connection. 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 P0717 2016 Chevrolet Silverado Description

The Input Speed Sensor detects the primary pulley revolution speed and sends a signal to the Transmission. The Input Speed Sensor (ISS), also known as the transmission turbine speed sensor, is a hall-effect type sensor. The ISS mounts to the control valve upper body assembly and connects to the control solenoid (w/body and Transmission Control Module (TCM)) valve assembly through a wire harness and connector. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the Input/Output Speed Sensor (ISS/OSS) supply voltage circuit from the Transmission Control Module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, Torque Converter Clutch (TCC) slip speed, and gear ratio. The Diagnostic Trouble Code (DTC) will be set when the TCM detects turbine speed is less than 61 RPM and the output speed is greater than 500 RPM for 1 s.

Frequently Asked Questions about P0717 2016 Chevrolet Silverado Code

What does the OBDII code P0717 mean for a 2016 Chevrolet Silverado?

The P0717 code indicates that the Transmission Input Speed Sensor (TISS) circuit is not sending a signal to the Powertrain Control Module (PCM).

What are the common symptoms of code P0717 in a 2016 Chevrolet Silverado?

Symptoms include erratic shifting, transmission slipping, delayed shifting, reduced engine performance, or the transmission entering "limp" mode.

What causes the P0717 code to appear in a 2016 Chevrolet Silverado?

Common causes include a faulty input speed sensor, damaged sensor wiring, poor electrical connections, or issues with the transmission control module.

Can driving with a P0717 code damage my 2016 Chevrolet Silverado?

Yes, driving with this code can cause further transmission damage and may lead to unsafe driving conditions due to improper shifting.

How do you diagnose a P0717 code in a 2016 Chevrolet Silverado?

Diagnosis involves checking the input speed sensor, inspecting the wiring and connectors, testing the sensor's electrical circuit, and scanning for related codes.

Can a low transmission fluid level cause the P0717 code in a 2016 Chevrolet Silverado?

While low transmission fluid can cause shifting issues, it typically does not directly trigger the P0717 code, but it should still be checked as part of the diagnosis.

How much does it cost to fix code P0717 on a 2016 Chevrolet Silverado?

Repair costs can vary between $150 and $400, depending on whether the input speed sensor needs replacement or if wiring repairs are required.

Is it necessary to reprogram the PCM after fixing code P0717 on a 2016 Chevrolet Silverado?

Reprogramming is not usually required unless the PCM itself is replaced or updated for related transmission issues.

Where is the input speed sensor located on a 2016 Chevrolet Silverado?

The input speed sensor is typically located on the transmission housing, near the input shaft.

What tools are needed to repair the P0717 code on a 2016 Chevrolet Silverado?

Tools may include a diagnostic scanner, multimeter, socket set, and possibly a transmission fluid drain pan if replacement of the sensor is required.
