The P2007 code on your 2020 Chrysler Pacifica indicates the intake manifold runner control for bank 2 is stuck in the open position. This code affects your Pacifica's 3.6L Pentastar V6 engine's variable intake system, reducing low-RPM torque and possibly affecting fuel economy.
Understanding P2007 on Chrysler Pacifica
While P2006 indicates stuck closed, P2007 indicates the opposite condition for bank 2 - runners are stuck open. This affects low-RPM performance because the intake cannot create the higher air velocity needed for optimal torque at lower engine speeds. The condition may be more noticeable during acceleration from a stop.
Common Symptoms
- Check engine light on
- Reduced low-RPM torque
- Sluggish acceleration from stop
- May feel underpowered at low speeds
- Possible rough idle
- Highway performance may be normal
- Slightly reduced fuel economy
Primary Causes
- IMRC actuator stuck or failed in open position
- Broken return spring in runner system
- Mechanical damage holding runners open
- IMRC position sensor reading incorrectly
- Actuator wiring open preventing closed command
- Vacuum leak affecting vacuum-operated systems
- Carbon buildup preventing closure
Diagnostic Procedure for 2020 Pacifica
Using Stellantis scan tool, command IMRC to close and observe position sensor feedback. If position doesn't change, check actuator operation. With engine off, manually check if runners can move closed. Inspect for broken springs or mechanical damage. Test actuator motor/solenoid for proper response to close commands. Check vacuum supply if vacuum-operated system.
Repair Solutions
Replace broken return springs holding runners in open position. Repair or replace failed IMRC actuator. Clean carbon buildup that may prevent full closure. Repair actuator wiring if open circuit prevents close commands. If mechanical damage is present, intake manifold repair or replacement may be needed. Clear codes and verify runners close properly when commanded.
