- Short distances only
- DIY difficulty
- moderate
- Estimated cost
- $100 - $400 (parts and labor)
Common Misconceptions / Fact Check
-
Commonly claimedSeveral code lists pair P2009 with heavy-duty diesel trucks (6.7 Power Stroke, 6.7 Cummins, 6.6 Duramax).
VerifiedP2009 is a gasoline Intake Manifold Runner Control (IMRC) circuit code -- common on VW/Audi 2.0T and BMW N54/N55. Those diesels do not use the gasoline-style variable-runner intake the code monitors.

Check wiring for shorts to ground between solenoid and PCM
-
Measure solenoid circuit voltage and resistance
Frequently Asked Questions
What does P2009 mean?
P2009 indicates the intake manifold runner control circuit on Bank 1 has a low voltage condition, typically caused by a short to ground in the wiring or a failed solenoid.
Can I drive with a P2009 code?
Short-distance driving is safe, but expect reduced performance. The intake runner flaps will not operate correctly.
How much does it cost to fix P2009?
Repair costs are typically $100 to $400, depending on whether the issue is a wiring fault or a solenoid replacement.
