Code P2150 2017 GMC Sierra Description
The diagnostic trouble code P2150 in a 2017 GMC Sierra specifically refers to an issue with the Cylinder 2 Injector High Control Circuit having low voltage. This code indicates that the powertrain control module (PCM) has detected that the voltage in the control circuit for the fuel injector in cylinder 2 is lower than the specified range. This can lead to improper fuel delivery to the engine, resulting in a range of performance issues.
Common Causes of P2150 2017 GMC Sierra
- Wiring issues or damaged wiring harness
- Faulty fuel injector
- Malfunctioning PCM
- Fuel injector driver within the PCM is faulty
- Poor electrical connection or corrosion in the circuit
Symptoms of P2150 2017 GMC Sierra
- Rough idling
- Misfires
- Hesitation or lack of power during acceleration
- Decreased fuel efficiency
- Engine stalling
How to Fix P2150 2017 GMC Sierra
- Diagnose the specific cause of the low voltage in the control circuit for cylinder 2 injector using a scan tool and multimeter.
- Inspect the wiring harness and connectors for any damage or corrosion. Repair or replace as necessary.
- Test the fuel injector for proper operation and replace if found to be faulty.
- Check the PCM for any malfunctions and reprogram or replace if needed.
- Clear the trouble code from the PCM memory and perform a test drive to ensure the issue has been resolved.
Cost to Fix P2150 2017 GMC Sierra
The typical repair costs for addressing a cylinder 2 injector high control circuit low voltage issue can range from $150 to $500, depending on the specific cause of the problem and the cost of parts and labor.

Frequently Asked Questions about P2150 2017 GMC Sierra Code
1. What does the OBDII code P2150 mean on a 2017 GMC Sierra?
P2150 indicates a problem with the Cylinder 2 Injector High Control Circuit, specifically a low voltage issue detected by the engine control module (ECM).
2. What are the common symptoms of a P2150 code?
Symptoms may include rough idling, misfires, poor fuel economy, reduced engine performance, and the Check Engine Light turning on.
3. What causes the P2150 code to appear?
Common causes include a faulty fuel injector, damaged wiring or connectors in the injector circuit, a malfunctioning ECM, or corrosion on electrical contacts.
4. How is the P2150 code diagnosed?
Technicians will scan the ECM for codes, inspect the Cylinder 2 injector and its wiring for damage or corrosion, check the injector's resistance, and test the ECM's output to the injector.
5. Can I drive with a P2150 code on my 2017 GMC Sierra?
It is not recommended to drive with this code, as it can lead to poor performance, increased emissions, and potential engine damage if the problem persists.
6. How do I fix the P2150 code?
Repairs may involve replacing the faulty injector, repairing or replacing damaged wiring or connectors, cleaning corroded terminals, or, in rare cases, replacing the ECM.
7. How much does it cost to fix a P2150 code?
The cost varies depending on the issue. Replacing a fuel injector typically costs $200–$400, while repairing wiring or connectors may cost less. ECM replacement can cost $500–$1,500.
8. Can a bad fuel injector cause a P2150 code?
Yes, a malfunctioning fuel injector is a common cause of the P2150 code, as it can disrupt the voltage signal in the control circuit.
9. What tools are needed to diagnose a P2150 code?
Tools may include an OBDII scanner, a multimeter for testing voltage and resistance, and possibly a noid light to check injector pulse.
10. Is the P2150 code specific to the 2017 GMC Sierra?
No, this code can appear on other vehicles with OBDII systems, but the specific diagnosis and repair steps may vary by make and model.
