GM Vehicle Error Code P1416: How to Fix It

Q: Can I drive with GM error code P1416?

Yes, P1416 is not a critical safety issue and won't prevent driving. However, it may cause increased emissions and potential check engine light illumination. Address it promptly to maintain proper emission control function.

Q: What causes GM P1416 error code?

Common causes include a faulty air injection pump, clogged or damaged vacuum hoses, defective check valves, failed solenoid valve, or blockages in the air injection system lines leading to bank 2.

Q: How much does it cost to fix P1416 on a GM vehicle?

Repair costs vary depending on the root cause. Hose replacement may cost $50-150, check valves $75-200, solenoid valve $100-300, while air injection pump replacement can range from $300-800 including labor.

Q: Will P1416 cause my GM to fail emissions testing?

Yes, P1416 can cause emissions test failure as it relates to the secondary air injection system that helps reduce exhaust emissions during cold starts. The error must be resolved before passing emissions testing.

Q: Is P1416 the same on all GM vehicles?

P1416 generally has the same meaning across GM vehicles (Secondary AIR system bank 2 incorrect flow), but the specific components and repair procedures may vary between different GM models, engines, and model years.

Abstract

GM error code P1416 indicates the Secondary AIR (air injection) system on bank 2 is not functioning properly or has incorrect airflow. This system helps reduce emissions during cold starts by pumping fresh air into the exhaust stream to help burn remaining fuel vapors.
