Code P216F Buick Description
The P216F Buick code indicates a problem with the Cylinder 6 Injector High Control Circuit High Voltage. This means that there is an issue with the fuel injector in cylinder 6 of the engine receiving too much voltage, which can lead to a variety of performance issues. The fuel injector is responsible for delivering the right amount of fuel into the combustion chamber at the right time. When the voltage to the fuel injector is too high, it can cause an imbalance in the air-fuel mixture, resulting in poor engine performance, reduced fuel efficiency, and potentially even engine misfires.
Common Causes of P216F Buick
- Faulty fuel injector
- Wiring or connector issues in the injector control circuit
- ECM malfunction
- Electrical short or open in the injector circuit
- Voltage regulator malfunction
Symptoms of P216F Buick
- Reduced engine performance
- Poor fuel efficiency
- Engine misfires
- Rough idling
- Illumination of the Check Engine Light
How to Fix P216F Buick
- Diagnose the issue by using a scan tool to check for the specific cylinder 6 injector high control circuit high voltage fault code.
- Inspect the wiring and connectors in the injector control circuit for any damage or corrosion. Repair or replace as necessary.
- Test the fuel injector in cylinder 6 to ensure it is functioning properly. Replace if faulty.
- Check the voltage regulator and ECM for proper operation. Replace if necessary.
- Clear the fault code and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P216F Buick
The typical repair costs for addressing a Cylinder 6 Injector High Control Circuit High Voltage issue can vary depending on the specific cause of the problem.

Frequently Asked Questions about P216F Buick Code
1. What does the OBDII code P216F mean for a Buick?
P216F indicates that the Engine Control Module (ECM) has detected a high voltage condition in the control circuit for the injector on cylinder 6.
2. What are the common symptoms of code P216F in a Buick?
Symptoms may include rough idling, engine misfires, reduced fuel efficiency, hesitation during acceleration, and the check engine light being illuminated.
3. What causes the P216F code to appear?
Common causes include a faulty fuel injector, damaged wiring or connectors in the injector circuit, a malfunctioning ECM, or excessive resistance in the circuit.
4. Can I drive my Buick with a P216F code?
Driving with this code is not recommended, as it may lead to poor engine performance, potential engine damage, or unsafe driving conditions.
5. How do I diagnose the P216F code?
Diagnosis involves using a multimeter to check for proper voltage and continuity in the cylinder 6 injector circuit, inspecting wiring and connectors for damage, and testing the fuel injector itself.
6. How is the P216F code fixed on a Buick?
Repairs may include replacing the cylinder 6 fuel injector, repairing or replacing damaged wiring or connectors, or, in rare cases, reprogramming or replacing the ECM.
7. Can a bad fuel injector cause the P216F code?
Yes, a faulty or shorted fuel injector can lead to excessive voltage in the control circuit, triggering the P216F code.
8. How much does it cost to repair a P216F code?
Repair costs vary but may range from $150 to $500, depending on whether the issue is with the fuel injector, wiring, or ECM.
9. Can a dirty fuel injector cause the P216F code?
No, a dirty injector typically causes poor fuel flow, not high voltage. This code is more likely related to electrical issues in the injector circuit.
10. How can I prevent the P216F code from recurring?
Regular maintenance, including inspecting and cleaning fuel injectors and checking wiring for wear, can help prevent this code from returning.
