P2007
Intake Manifold Runner Control Stuck Closed Bank 2P2007 is a generic OBD-II powertrain diagnostic trouble code: Intake Manifold Runner Control Stuck Closed Bank 2. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.
What P2007 means
P2007 is the Bank 2 counterpart to P2006. It is stored when the PCM detects that the intake manifold runner control (IMRC) actuator on Bank 2 — the cylinder bank that does NOT contain cylinder #1 — is commanded open but remains stuck in the closed position. Like P2006, this code is only relevant to engines equipped with variable intake runner systems and applies exclusively to V-configuration or flat engines that have two physically separate cylinder banks.
The IMRC system improves volumetric efficiency across the RPM range by shortening effective intake runner length at high RPM (open flap) and lengthening it at low RPM (closed flap). When Bank 2 runners are stuck closed, the affected cylinders are starved of airflow above approximately 3,000 RPM, producing an asymmetric breathing imbalance between the two banks. The ECU may compensate by trimming fuel on Bank 2, leading to a noticeable lean-side imbalance in long-term fuel trim data.
Causes are identical to P2006 but located on the opposite bank: carbon-fouled flap shafts, failed actuator, broken linkage, cracked vacuum hoses, or wiring faults. On many V6 and V8 platforms both banks share a common IMRC control strategy, so P2006 and P2007 frequently appear together. If both codes are present simultaneously, a shared component such as the central IMRC control solenoid or PCM output driver is the likely culprit rather than two separate mechanical failures.
Diagnosis should include a bank-to-bank comparison of IMRC position sensor feedback voltages under identical throttle conditions. A healthy bank will show a clear voltage transition as the runners open; the faulty bank will show a static low voltage regardless of commanded position. Repair approach mirrors P2006 — clean carbon deposits first, then inspect linkage, then test and replace the actuator as needed.
Common causes
Most-frequently reported root causes when P2007 is logged.
-
1
Carbon buildup on Bank 2 IMRC runner flap shafts (most common)
-
2
Failed or seized Bank 2 IMRC actuator motor or solenoid
-
3
Broken or binding IMRC linkage rod on Bank 2
-
4
Cracked or disconnected vacuum line to Bank 2 actuator
-
5
Shared IMRC control solenoid failure (when P2006 is also present)
-
6
Wiring harness damage or connector corrosion on Bank 2 circuit
-
7
Faulty Bank 2 IMRC position sensor
-
8
PCM output driver fault for Bank 2 IMRC channel

How to diagnose P2007
A typical diagnostic flow when this code is present.
-
1
Retrieve all stored codes; if P2006 is also present, investigate the shared IMRC solenoid or PCM driver before bank-specific components
-
2
Clear codes and road-test with a focus on high-RPM acceleration to confirm P2007 resets
-
3
Visually inspect Bank 2 IMRC actuator, linkage, and vacuum lines for obvious damage or disconnection
-
4
Compare live IMRC position sensor voltage for Bank 1 vs Bank 2 at idle and at elevated RPM using a scan tool
-
5
Manually attempt to move the Bank 2 runner flaps to check for carbon seizure
-
6
Test actuator motor resistance and control circuit voltage on Bank 2 with a multimeter
-
7
If both banks are affected, test the common IMRC solenoid valve and PCM output circuit before replacing individual actuators

Frequently asked questions
Can P2006 and P2007 appear at the same time?
Yes. When both codes are present simultaneously, a shared component failure is the most likely cause — typically a central IMRC solenoid, vacuum reservoir, or PCM driver circuit.
Which side of the engine is Bank 2?
Bank 2 is the cylinder bank that does NOT contain cylinder number 1. Always verify in the vehicle's service manual.
Is P2007 more serious than P2006?
Both codes have similar severity. The combined impact of P2006 and P2007 together is significantly worse than either alone.
Will P2007 cause a failed emissions test?
Yes. Any active stored DTC that illuminates the Check Engine Light will cause an automatic failure on most emissions inspection programmes.
Can I clean the IMRC flaps without removing the intake manifold?
On some engines, spraying intake manifold cleaner through the throttle body with the engine running can dissolve light carbon deposits. For heavy deposits, manifold removal is usually required.
Disabling P2007 in software
RaceTune can permanently disable P2007 — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.
Software modifications affect emissions compliance and are not road-legal in many jurisdictions. RaceTune service files are intended for motorsport, off-road, and export use.
