Intake Manifold Tuning Valve Position Sensor Circuit High Bank 2
The P207D code indicates that the Engine Control Module (ECM) has detected a voltage signal from the Intake Manifold Tuning (IMT) valve position sensor on Bank 2 that is higher than the expected range. This sensor monitors the position of the IMT valve, which adjusts intake runner length to optimize engine performance across RPM ranges. A high circuit condition typically points to a short to voltage, a faulty sensor, or a wiring issue. This can cause the IMT valve to malfunction, affecting engine power and fuel economy.
1. Most Common Causes
- Faulty Bank 2 IMT valve position sensor (internal open circuit)
- Damaged, corroded, or shorted-to-voltage wiring or connectors in the signal, 5V reference, or ground circuit
- Mechanically stuck or broken IMT valve preventing sensor movement
- Internal PCM failure (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the IMT valve connector and wiring for damage or corrosion.
Step 3: Test the sensor voltage reference (typically 5V) and ground at the connector.
Step 4: Measure the sensor signal voltage; compare to manufacturer specs (usually 0.5-4.5V).
Step 5: If signal voltage is above 4.5V, check for short to voltage or replace the sensor.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause reduced performance and potential damage to the IMT valve or engine.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor, depending on the cause and vehicle model.
