P207D - Intake Manifold Tuning Valve Position Sensor Circuit High Bank 2
The P207D code indicates that the Powertrain Control Module (PCM) has detected a high voltage signal from the Intake Manifold Tuning (IMT) valve position sensor on Bank 2. This sensor monitors the position of the IMT valve, which adjusts intake runner length to optimize engine performance. A high voltage reading suggests a short to power, open circuit, or a faulty sensor. This can cause improper valve operation, affecting engine power and fuel economy.
01. Most Common Causes
- Faulty IMT valve position sensor
- Short to power in sensor circuit
- Open or damaged wiring/connector
- Corroded or loose electrical connections
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
- Possible rattling noise from intake
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P207D and check for related codes.
Step 2: Visually inspect the IMT valve actuator and wiring harness for damage, corrosion, or loose connections.
Step 3: Test the sensor voltage and ground circuits with a multimeter; compare to manufacturer specs.
Step 4: If circuit is okay, replace the IMT valve position sensor.
Step 5: Clear codes and test drive to verify repair.
