Quick answer

For Chevrolet, verified NHTSA manufacturer communications list P2263 among codes that may occur with reduced engine power. They state that a leak in the charge-air-cooler/induction system may be involved and direct technicians to follow GM Service Information (SI) diagnostics. This evidence is not specific to the supplied Bolt EV, Spark, or Volt applicability records.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P2263 mean?

For Chevrolet, verified NHTSA manufacturer communications list P2263 among codes that may occur with reduced engine power. They state that a leak in the charge-air-cooler/induction system may be involved and direct technicians to follow GM Service Information (SI) diagnostics. This evidence is not specific to the supplied Bolt EV, Spark, or Volt applicability records.

2. Technical explanation

The supplied verified evidence does not provide a conventional component-level definition for P2263. Its recorded canonical meaning is a service instruction: follow SI diagnostics; if no cause is found or a leak check is needed during diagnosis, a GE-52250 Power Smoke Diagnostic Leak Detector may be helpful. The cited communications associate P2263 with a possible charge-air-cooler/induction-system leak in the covered vehicle context.

3. What system is affected?

Charge-air-cooler/induction system, as described in the cited manufacturer communications. Whether this applies to a particular Chevrolet Bolt EV, Spark, or Volt is not yet established by verified evidence.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Reduced engine power may be present in the vehicle context covered by the cited manufacturer communications.
  • No symptoms specific to the supplied Bolt EV, Spark, or Volt applicability records are established by verified evidence.

6. Possible causes

  • A leak in the charge-air-cooler/induction system may be a cause in the context covered by the cited manufacturer communications.
  • Any other cause is not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis using the applicable Chevrolet/GM Service Information procedures.
  • Do not attempt high-voltage repair procedures based on this code.
  • Record whether reduced power is present and provide the full diagnostic-code scan results to the servicing technician.

10. Step-by-step troubleshooting

  1. A technician should follow SI diagnostics.
  2. If no cause is found, or if diagnosis requires a leak check, the manufacturer communication states that a GE-52250 Power Smoke Diagnostic Leak Detector can be helpful.
  3. Specific test steps, measurements, and vehicle applicability are not yet established by the supplied verified evidence.

11. When to contact service

Service is appropriate because the verified manufacturer communication directs technicians to use SI diagnostics. The supplied evidence does not establish urgency, drivability, charging status, or an EV-specific repair path.

12. What the service center may check

  • Retrieve and follow the applicable GM Service Information diagnostic procedure.
  • Evaluate for a charge-air-cooler/induction-system leak where applicable.
  • Use a GE-52250 Power Smoke Diagnostic Leak Detector if no cause is found or a leak check is required during diagnosis.

13. Possible repair or resolution

  • The verified evidence does not identify a specific repair.
  • Resolution depends on the result of the applicable SI diagnostic procedure and any required leak check.
