What P207D means
The bank 2 valve position signal reads above the highest value the controller accepts. Electrically that points at a broken sensor ground or a short from the signal to a supply voltage. There is no published manufacturer use of P207D; it mirrors GM's bank 1 code P2078, where 5 % or less counts as high due to the reversed scale, while GM's 2023/2024 logic compares the raw voltage with about 4.8 V. An open ground often comes from heat-damaged connectors on the rear bank, so inspect the plug before ordering a new actuator. Unlike P207B, a high code says nothing about the flap mechanics; the valve may move correctly while its feedback is simply not readable.
P207D at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P207D
- Check engine light (manufacturer-dependent)
- No driveability change in most cases
Common causes of P207D
- Most likelySensor ground open at a heat-damaged connector
- PossibleSignal wire shorted to 5 V or battery voltage
- Less likelyBank 2 actuator electronics defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P207D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 7D | The exact fault in that area. |
What to do next
- Note P207D and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P207D
What does P207D mean?
P207D means "Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit High (Bank 2)". The bank 2 valve position signal reads above the highest value the controller accepts. It is a generic code, so it means the same on every make.
Is it safe to drive with P207D?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P207D fail an emissions test?
Yes, it can. P207D is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P207D to fix?
Difficulty: easy. A typical repair takes 0.3 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P207D clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
