What is P1416?
P1416 indicates a malfunction in the Secondary Air Injection (AIR) system's port air circuit for engine bank 2, which is part of the emissions control system. This medium-severity code is triggered when the powertrain control module detects an airflow issue, often related to vacuum leaks or electrical problems, and is most commonly reported in Chevrolet Corvette models. It can cause the check engine light to illuminate and may affect emissions performance.
Common Causes:
- Vacuum leaks, often induced by battery acid corrosion (mentioned in 22% of reports)
- Electrical gremlins or software issues in control modules (mentioned in 17% of reports)
- Faulty or broken components in the AIR system, such as valves or brackets (mentioned in 13% of reports)
Symptoms:
- Check engine light illumination, sometimes accompanied by other codes like P0410 (reported in 11% of cases)
- Intermittent electrical issues that may resolve after a few starts (reported in 9% of cases)
- No noticeable drivability issues, with the code appearing as a standalone warning (reported in most cases)
