P2690 GMC Code - Cylinder 5 Injector Data Incompatible
Quick Answer
The P2690 code for GMC vehicles indicates that there is an issue with the injector data for cylinder 5, specifically that the data being received is incompatible with what is expected by the engine control module (ECM). Common causes include Faulty injector: A faulty injector could be sending incorrect data to the ECM, causing the incompatibility issue, Wiring issues: Damaged or faulty wiring connecting the injector to the ECM could disrupt the data transmission, ECM problem: A malfunctioning ECM could be misinterpreting the data received from the injector for cylinder 5. 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 P2690 GMC Description
The P2690 code for GMC vehicles indicates that there is an issue with the injector data for cylinder 5, specifically that the data being received is incompatible with what is expected by the engine control module (ECM). This can lead to a variety of performance issues, as the injector plays a crucial role in delivering the proper amount of fuel to the cylinder for combustion. When the injector data is incompatible, it can result in improper fuel delivery, leading to a misfire, rough idle, decreased fuel efficiency, and potentially even engine damage if left unresolved.
Common Causes of P2690 GMC
- Faulty injector: A faulty injector could be sending incorrect data to the ECM, causing the incompatibility issue.
- Wiring issues: Damaged or faulty wiring connecting the injector to the ECM could disrupt the data transmission.
- ECM problem: A malfunctioning ECM could be misinterpreting the data received from the injector for cylinder 5.
- Mechanical issue: There could be a mechanical issue within cylinder 5 itself, affecting the injector data compatibility.
Symptoms of P2690 GMC
- Rough idle: The engine may idle roughly or inconsistently due to improper fuel delivery to cylinder 5.
- Misfires: The vehicle may experience misfires, causing a noticeable decrease in performance and potential damage to the engine over time.
- Decreased fuel efficiency: Incompatible injector data can lead to inefficient fuel delivery, resulting in decreased fuel efficiency and increased fuel consumption.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard, indicating a problem with the injector data for cylinder 5.
How to Fix P2690 GMC
- Diagnose the issue: Use a diagnostic scanner to retrieve the specific code and further investigate the injector data for cylinder 5.
- Inspect the injector: Check the injector for any visible signs of damage or malfunction and test its functionality.
- Check wiring: Inspect the wiring connecting the injector to the ECM for any damage or loose connections, repairing or replacing as needed.
- Test the ECM: Test the ECM to ensure it is accurately interpreting the data from the injector for cylinder 5.
- Clear the code: After addressing the underlying issue, clear the code from the ECM to reset the system and monitor for any reoccurrence of the problem.
Cost to Fix P2690 GMC
The cost estimate for resolving the P2690 code for GMC vehicles can vary depending on the specific cause of the issue. On average, the repair costs for this type of problem can range from $200 to $500, including parts and labor. However, it is important to note that the actual cost may be higher or lower based on factors such as the location of the repair shop, the make and model of the vehicle, and the extent of the repairs needed. It is recommended to consult with a professional mechanic to get a more accurate estimate based on the specific circumstances of the vehicle in question.
