Code P2147 2016 Chevrolet Silverado Description
The P2147 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates an issue with the Cylinder 1 Injector High Control Circuit Low Voltage. This code specifically points to a problem with the electrical circuit that controls the fuel injector for cylinder 1 in the engine. The fuel injector is responsible for delivering the precise amount of fuel into the combustion chamber for ignition. When the control circuit voltage is too low, it can lead to improper fuel delivery, affecting the engine's performance and efficiency.
Common Causes of P2147 2016 Chevrolet Silverado
- Faulty fuel injector for cylinder 1
- Wiring or connector issues in the injector control circuit
- ECM software or hardware malfunction
- Corrosion or damage to the electrical connections
- Fuel system issues affecting injector performance
Symptoms of P2147 2016 Chevrolet Silverado
- Engine misfires
- Rough idling
- Reduced fuel efficiency
- Engine stalling
- Check Engine Light illuminated
How to Fix P2147 2016 Chevrolet Silverado
- Begin by conducting a visual inspection of the wiring and connectors in the injector control circuit for cylinder 1. Look for any signs of damage, corrosion, or loose connections.
- Test the fuel injector for cylinder 1 to ensure it is functioning properly. This may involve using a multimeter to check for proper resistance and continuity.
- If the injector and wiring are in good condition, proceed to check the ECM for any software or hardware issues. This may require diagnostic tools to scan for faults and reprogram the ECM if necessary.
- Clear the DTC and reset the ECM to see if the code returns. If it does not reappear, the issue may have been resolved. However, if the code persists, further troubleshooting may be needed.
Cost to Fix P2147 2016 Chevrolet Silverado
The cost of repairing a P2147 code on a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue.

5. How do I diagnose code P2147 in a 2016 Chevrolet Silverado?
To diagnose, inspect the fuel injector’s wiring and connectors for damage, test the injector’s resistance, and check the ECM or injector control module for faults using a multimeter or scan tool.
6. How much does it cost to fix code P2147 on a 2016 Chevrolet Silverado?
The repair cost can vary depending on the cause, but replacing a fuel injector typically costs between $200 and $400, while fixing wiring issues or replacing the ECM may cost more.
7. Can a dirty fuel injector cause code P2147?
No, a dirty fuel injector typically does not cause this code. P2147 specifically refers to an electrical circuit issue, not a mechanical clog or obstruction.
8. What tools do I need to troubleshoot a P2147 code?
You will need a scan tool to read the code, a multimeter to test electrical circuits, and possibly a wiring diagram for the fuel injector control system.
9. Will clearing the code fix P2147 on a 2016 Chevrolet Silverado?
Clearing the code without addressing the underlying issue will not fix the problem. The code will likely return unless the fault in the injector circuit is repaired.
10. Can a bad ECM cause the P2147 code on my 2016 Chevrolet Silverado?
