What Are the Symptoms of P2009?
- Check Engine Light illuminated
- Engine performance reduction
- Erratic idle
- Hesitation on acceleration
- Slightly higher fuel consumption
What Causes P2009? (Most Likely First)
- Short to ground in runner control solenoid wiring Very High
- Failed intake manifold runner control solenoid High
- Water intrusion in connector Moderate
- Damaged wiring harness Moderate
- PCM internal driver fault Low
Can I Still Drive with P2009?
Short distances only. P2009 is rated moderate severity. Keep trips short and get it diagnosed soon rather than waiting for symptoms to worsen.
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.

-
Measure solenoid circuit voltage and resistance
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 diesel engines do not use the gasoline-style variable-runner intake the code monitors.
