B0560 2017 GMC Sierra Code - Engine RPM Input Circuit Signal Invalid

Quick Answer

The B0560 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates that there is an issue with the Engine RPM Input Circuit Signal, specifically that the signal being received is deemed invalid by the vehicle's onboard computer system. Common causes include Faulty RPM Sensor: A malfunctioning RPM sensor can send incorrect signals to the ECM, triggering this code, Wiring Issues: Damaged or corroded wiring connecting the RPM sensor to the ECM can disrupt the signal transmission, ECM Malfunction: A problem with the engine control module itself can also lead to an invalid RPM signal. 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 B0560 2017 GMC Sierra Description

The B0560 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates that there is an issue with the Engine RPM Input Circuit Signal, specifically that the signal being received is deemed invalid by the vehicle's onboard computer system. This code typically points to a problem with the communication between the engine control module (ECM) and the RPM sensor. The RPM sensor is responsible for monitoring the engine's revolutions per minute, providing crucial data for the ECM to adjust fuel injection, ignition timing, and other engine functions. When the ECM receives an invalid signal from the RPM sensor, it can lead to performance issues and potential long-term damage if left unresolved.

Common Causes of B0560 2017 GMC Sierra

  1. Faulty RPM Sensor: A malfunctioning RPM sensor can send incorrect signals to the ECM, triggering this code.
  2. Wiring Issues: Damaged or corroded wiring connecting the RPM sensor to the ECM can disrupt the signal transmission.
  3. ECM Malfunction: A problem with the engine control module itself can also lead to an invalid RPM signal.
  4. Loose Connections: Loose or poor connections between the RPM sensor and the ECM can cause signal interruptions.
  5. Software Glitch: Occasionally, a software glitch in the vehicle's computer system can result in an invalid RPM signal being detected.

Symptoms of B0560 2017 GMC Sierra

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
  2. Engine Misfires: An invalid RPM signal can cause the engine to misfire or run rough, leading to a noticeable decrease in performance.
  3. Stalling: The engine may stall unexpectedly due to incorrect RPM data being received by the ECM.
  4. Poor Fuel Efficiency: The vehicle may experience a decrease in fuel efficiency as a result of the ECM not receiving accurate RPM information.
  5. Difficulty Starting: In some cases, the vehicle may have difficulty starting or may not start at all due to the RPM signal issue.

How to Fix B0560 2017 GMC Sierra

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and pinpoint the exact cause of the invalid RPM signal.
  2. Inspect RPM Sensor: Check the RPM sensor for any signs of damage or malfunction and replace if necessary.
  3. Check Wiring: Inspect the wiring harness for any damage or corrosion, repairing or replacing as needed.
  4. Test ECM: Test the engine control module to ensure it is functioning properly and replace if deemed faulty.
  5. Clear Codes: After completing the repairs, clear the trouble codes from the vehicle's computer system to reset the check engine light.

Cost to Fix B0560 2017 GMC Sierra

The cost of repairing a B0560 code on a 2017 GMC Sierra can vary depending on the specific cause of the issue and the labor rates in your area. On average, you can expect to pay anywhere from $150 to $400 for parts and labor to address this problem.
