Frequently Asked Questions

Can I drive with error code P2005?
Yes, but it may cause reduced performance and fuel economy. You should fix it soon to avoid potential damage or failed emissions tests.
What is Bank 2?
Bank 2 refers to the side of the engine that does not contain cylinder #1. In V6 or V8 engines, it's the opposite bank from cylinder #1. For inline engines, there is only one bank.
How much does it cost to fix P2005?
DIY cost can range from $50 for a can of cleaner to $200+ for a new IMRC actuator. Professional repair typically costs $250-$600 including labor.
Can carbon buildup cause P2005?
Yes, heavy carbon deposits on the intake runner flaps can prevent them from moving freely, causing a stuck open condition. Cleaning may resolve the issue.
Will P2005 clear itself?
The code may clear after a few drive cycles if the issue is intermittent, but the underlying problem should be fixed to prevent it from returning.
