Can drive — fix at your convenience.
This code means the engine computer detected a problem in the control circuit for the secondary air injection system relay 'A'. This relay switches power to the air pump and related components used to lower emissions during cold starts. Fixes usually involve replacing the relay, repairing wiring or connectors, and the work is generally inexpensive.
$100 – $400
Varies by vehicle and root cause.
Yes, it's generally safe to keep driving. The relay only powers the cold-start emissions system, so your car performs normally. Get it repaired before an emissions test.
Typically around $100 to $400. The relay itself is often inexpensive, so cost mostly depends on labor and whether wiring repairs are needed.
No, it's a low-severity emissions code. It won't damage the engine or strand you, but it keeps the check engine light on and can cause an emissions failure.
It acts as an electrical switch that turns on the air injection pump and valves during cold starts. When the relay or its circuit fails, the system can't run and the computer sets this code.
