Intake Manifold Tuning Valve Position Sensor Circuit Bank 2
The P207A code indicates a problem with the intake manifold tuning (IMT) valve position sensor or its circuit on bank 2. This sensor monitors the position of the IMT valve, which adjusts intake runner length for optimal performance. A fault can cause incorrect valve operation, affecting engine power and fuel economy.
1. Most Common Causes
- Faulty IMT valve position sensor
- Wiring or connector issues in the sensor circuit
- Carbon buildup on the IMT valve
- Failed IMT actuator or control module
2. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
3. Step-by-Step Diagnosis
1. Scan for codes and record freeze frame data.
2. Visually inspect the IMT valve and sensor wiring for damage or corrosion.
3. Test the sensor signal voltage with a multimeter while manually operating the valve.
4. Check for carbon buildup and clean the IMT valve if necessary.
