P207C Code - Intake Manifold Tuning Valve Position Sensor/Switch Circuit Low Bank 2
Quick Answer
The Intake Manifold Tuning Valve (IMTV) is a motorized actuated unit mounted directly to the intake manifold. Common causes include Faulty Intake Manifold Tuning Valve Position Sensor/Switch, Intake Manifold Tuning Valve Position Sensor/Switch harness is open or shorted, Intake Manifold Tuning Valve Position Sensor/Switch circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P207C Description
The motorized IMTV unit will not be energized below approximately 2600 rpm or higher on some vehicles. The shutter will be in the closed position not allowing airflow blend to occur in the intake manifold. Above approximately 2600 rpm or higher, the motorized unit will be energized. The motorized unit will be commanded on by the PCM initially at a 100 percent duty cycle to move the shutter to the open position and then falling to approximately 50 percent to continue to hold the shutter open.
The Intake Manifold Tuning Valve (IMTV) system is monitored for failure during continuous, Key ON Engine OFF (KOEO), or Key ON Engine Running (KOER) self-tests. The test fails when the signal is more or less than an expected calibrated range.
What are the Possible Causes of the DTC P207C?
- Faulty Intake Manifold Tuning Valve Position Sensor/Switch
- Intake Manifold Tuning Valve Position Sensor/Switch harness is open or shorted
- Intake Manifold Tuning Valve Position Sensor/Switch circuit poor electrical connection
- Faulty Intake Manifold Tuning Valve (IMTV)
- Faulty Intake Manifold Runner Control (IMRC)
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P207C?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P207C code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
