The P2004 code on your 2022 Dodge Durango indicates an electrical fault in the intake manifold runner control circuit for bank 1. This code affects your Durango's 3.6L Pentastar V6 or 5.7L HEMI V8 engine's variable intake system, signaling a circuit problem rather than a stuck position issue.
Understanding P2004 on Dodge Durango
Unlike P2006/P2007 which indicate stuck positions, P2004 indicates an electrical circuit fault in the IMRC system for bank 1. This could be an open circuit, short circuit, or abnormal signal that prevents proper communication with or control of the IMRC actuator.
Common Symptoms
- Check engine light on
- Variable symptoms depending on default position
- May have reduced power at certain RPMs
- IMRC system may default to safe position
- Possible hesitation during acceleration
- Engine may run normally if system defaults appropriately
Primary Causes
- Damaged wiring to IMRC actuator
- Corroded IMRC connector
- Failed IMRC actuator motor or solenoid
- Open circuit in control wiring
- Short circuit to ground or power
- PCM driver circuit failure
- Water intrusion in connector
Diagnostic Procedure for 2022 Durango
Check IMRC actuator connector for corrosion, damage, or water intrusion. Test circuit resistance between PCM and actuator - should be low ohms. Check for shorts to ground or battery voltage. Test actuator motor/solenoid resistance and compare to specification. Verify PCM provides command signal when IMRC operation is requested. Inspect wiring harness for physical damage.
Repair Solutions
Repair damaged wiring in IMRC circuit. Clean or replace corroded connectors. Replace failed IMRC actuator if it tests faulty. Address water intrusion issues and seal connector properly. If PCM driver circuit is faulty, PCM diagnosis or replacement may be needed. Clear codes and verify proper circuit operation with scan tool monitoring.
