P207E: Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Intermittent (Bank 2)

Bank 2 version of the intermittent feedback fault: the valve position signal drops out or jumps for short moments, but returns to normal between events. No manufacturer documents P207E, and even its bank 1 twin P2079 has no published OEM use with this meaning. The diagnosis is therefore generic: since the fault may vanish before a scan tool is connected, freeze-frame data and the failure counter help to judge how often it happens. Heat cycling on the rear bank, vibration and water in the connector are the usual triggers. If the signal fails permanently, the code typically turns into the circuit or low/high variants P207A, P207C or P207D, which are easier to pinpoint.

Bank 2 is the side without cylinder 1, so it only exists on V or boxer engines.

Symptoms

• Intermittent warning light (manufacturer-dependent)
• Fault not reproducible in the workshop

Most likely causes

• Moisture or corrosion in the bank 2 sensor connector
• Solder joint or wire breaking open intermittently under heat
• Harness not clipped, contact lost under vibration

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the vacuum hoses and the connector
2. Gently move the wiring with the engine running and watch whether the reading changes.
3. Watch the actuator's movement with the scanner
4. Inspect the manifold for carbon buildup
5. Replace the actuator if it does not follow the command

Good to know

• Repair difficulty: medium
• It affects emissions.

What each character of P207E means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• 0: Subsystem depends on the code range
• 7E: Specific fault in that system

Frequently asked questions

Can I keep driving with code P207E?

You can drive in moderation. Get it repaired soon, because a loose flap can cause major damage on some engines.

What causes code P207E?

The most common causes are: moisture or corrosion in the bank 2 sensor connector; solder joint or wire breaking open intermittently under heat; harness not clipped, contact lost under vibration.
