P2007 trouble code definition
P2007 is a general OBD2 code that indicates a malfunction in the intake manifold runner control circuit.
This code is similar to P2004, P2005, P2006, P2008, P2009, P2010 and P2015.
What the P2007 code means
The P2007 code means the intake manifold runner is stuck closed for bank 2. The ECU controls how much to open or close the intake manifold runner flaps and when bank 2 is stuck open the P2007 code is set.
This triggers a Check Engine Light to be displayed on the dashboard and a failsafe mode to be enabled. The failsafe mode will remain until the intake manifold runner flap becomes unstuck or the code is cleared.
What causes the P2007 code?
- Intake runner bank 2 that is defective or clogged
- Wiring harness that has an open or short
- Faulty electrical connection
- Intake manifold runner control solenoid has failed
What are the symptoms of the P2007 code?
The most noticeable symptom of P2007 code is the Check Engine Light visible on the dashboard.
In some cases the vehicle may have a poor idle, loss of low end engine torque, and an engine that surges.
How does a mechanic diagnose the P2007 code?
Mechanics will use a scan tool to check for any codes stored in the ECU. All freeze frame data will be noted for use on the test drive.
Then all the codes will be cleared and the vehicle taken on a test drive, during the test drive the technician will attempt to recreate the conditions the code was set under.
A visual inspection will be done with special care to look for warn vacuum lines and damaged wiring.
Next, the scan tool will be used to monitor the live data stream while the engine is driven.
Lastly, a hand vacuum pump will be used to test the intake manifold runner control solenoid.
Common mistakes when diagnosing the P2007 code
Mistakes can be made when step are skipped or not completed in the proper order. These mistakes can trip up even the most experienced technicians.

- Wiring harness repaired or replaced
- Intake manifold runner bank 2 replaced or unclogged
- Poor electrical connection repaired
- Intake manifold runner solenoid replaced
Additional comments for consideration regarding the P2007 code
When diagnosing the P2007 code a few special tools may be needed to help:
An advanced level scan tool that gives access the the live engine data will be needed. These tell technicians live sensor and solenoid data.
The other tool is a hand vacuum pump, these are used to easily and safely check for vacuum leaks and to operate the solenoid.
