P07C0 2016 Chevrolet Silverado Code - Transmission Input Speed Sensor Circuit High Voltage

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 P07C0 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 the ISS signal circuit voltage is greater than 4.75 V for 0.8 s.

Frequently Asked Questions about P07C0 2016 Chevrolet Silverado Code

1. What does the OBDII code P07C0 mean for a 2016 Chevrolet Silverado?

The code P07C0 indicates a "Transmission Input Speed Sensor Circuit High Voltage," meaning the transmission input speed sensor is detecting voltage higher than expected by the control module.

2. What are the common symptoms of code P07C0 in a 2016 Chevrolet Silverado?

Symptoms may include erratic or delayed shifting, poor acceleration, the transmission slipping, or the vehicle going into limp mode.

3. What causes the P07C0 code to trigger in a 2016 Chevrolet Silverado?

Common causes include a faulty transmission input speed sensor, damaged wiring or connectors, a short circuit, or issues with the powertrain control module (PCM).

4. Can I continue driving my 2016 Chevrolet Silverado with a P07C0 code?

It is not recommended to drive the vehicle for an extended period, as the issue can lead to transmission performance problems and potential damage.

5. How do I diagnose the P07C0 code on a 2016 Chevrolet Silverado?

Diagnose the code by inspecting the wiring and connectors for damage, testing the input speed sensor for proper function, and using a scan tool to monitor sensor data and voltage levels.

6. How do I fix the P07C0 code on a 2016 Chevrolet Silverado?

Repairs may include replacing the transmission input speed sensor, repairing or replacing damaged wiring, or reprogramming or replacing the PCM if necessary.

7. How much does it cost to fix a P07C0 code on a 2016 Chevrolet Silverado?

Repair costs can vary but typically range from $150 to $400, depending on whether the issue is with the sensor, wiring, or PCM.

8. Can a bad battery cause the P07C0 code on a 2016 Chevrolet Silverado?

While uncommon, a weak or failing battery can cause voltage irregularities that may contribute to this code. Testing the battery and charging system is advisable.

9. Is the transmission input speed sensor difficult to replace on a 2016 Chevrolet Silverado?

The difficulty of replacing the speed sensor varies depending on its location, but it is generally a moderate job requiring basic tools and some mechanical knowledge.

10. Can a faulty PCM trigger the P07C0 code in a 2016 Chevrolet Silverado?

Yes, a malfunctioning PCM can misinterpret sensor signals or output incorrect voltages, leading to the P07C0 code. However, this is less common than sensor or wiring issues.
