P07BF 2016 Chevrolet Silverado Code - Transmission Input Speed Sensor Circuit Low 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 P07BF 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 less than 0.25 V for 0.8 s.

Frequently Asked Questions about P07BF 2016 Chevrolet Silverado Code

1. What does the OBDII code P07BF mean on a 2016 Chevrolet Silverado?

The P07BF code indicates a "Transmission Input Speed Sensor Circuit Low Voltage," meaning the sensor is detecting a voltage below the expected range.

2. What are the common symptoms of the P07BF code on a 2016 Chevrolet Silverado?

Symptoms may include erratic shifting, delayed gear engagement, transmission slipping, or the check engine light being illuminated.

3. What causes the P07BF code to appear on a 2016 Chevrolet Silverado?

Common causes include a faulty transmission input speed sensor, damaged wiring or connectors, low transmission fluid, or a malfunctioning powertrain control module (PCM).

4. Can I continue driving my 2016 Chevrolet Silverado with the P07BF code?

Driving with this code is not recommended, as it can lead to further transmission issues or unsafe driving conditions due to erratic shifting.

5. How do I fix the P07BF code on a 2016 Chevrolet Silverado?

Start by inspecting the wiring and connectors for damage or loose connections, check the transmission fluid level, and replace the transmission input speed sensor if necessary.

6. How much does it cost to repair the P07BF code on a 2016 Chevrolet Silverado?

The cost can vary but typically ranges from $150 to $300 for parts and labor, depending on whether the sensor or wiring needs replacement.

7. Can low transmission fluid cause the P07BF code?

Yes, low or contaminated transmission fluid can affect the input speed sensor's performance and trigger the P07BF code.

8. How do I diagnose the P07BF code on my 2016 Chevrolet Silverado?

Use an OBDII scanner to confirm the code, inspect the input speed sensor and its wiring, check the transmission fluid condition, and test sensor voltage with a multimeter.

9. Is the P07BF code specific to the 2016 Chevrolet Silverado?

No, the P07BF code can appear on other vehicles with similar transmission systems, but the diagnosis and repair steps may vary.

10. What happens if I ignore the P07BF code on my 2016 Chevrolet Silverado?

Ignoring the code can lead to worsening transmission issues, reduced performance, and potential damage to other components, resulting in more expensive repairs.
