P207E: IMT Valve Position Sensor Circuit Intermittent Bank 2
The P207E code indicates an intermittent fault in the intake manifold tuning (IMT) valve position sensor circuit for bank 2. This sensor monitors the position of the IMT valve, which adjusts intake runner length to optimize engine performance across RPM ranges. An intermittent signal suggests a loose connection, damaged wiring, or a failing sensor, leading to erratic valve operation and potential drivability issues.
1. Most Common Causes
- Faulty IMT valve position sensor
- Damaged or corroded wiring/connectors in the sensor circuit
- Loose electrical connection at the sensor or PCM
- Intermittent short or open in the circuit
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation during acceleration
- Poor fuel economy
- Rough idle or engine stalling
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data to capture conditions when the fault occurred.
Step 2: Visually inspect the IMT valve position sensor and its wiring harness for damage, corrosion, or loose connections.
Step 3: Use a multimeter to test sensor resistance and voltage signals per manufacturer specifications.
Step 4: Check for intermittent faults by wiggling the wiring harness while monitoring the sensor signal with a scan tool or oscilloscope.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the intermittent fault can cause sudden loss of power or poor engine performance, potentially leading to unsafe driving conditions.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150 for parts and labor, depending on whether the sensor needs replacement or just a wiring repair.
5. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
