P207C code meaning
Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Low (Bank 2)
Powertrain system Generic code P20xx codes Check engine light
What P207C means
Low signal on the position feedback of the bank 2 tuning valve: the controller sees a value below the window it accepts. Typical electrical causes are the signal shorted to ground or a missing 5 V supply. No manufacturer publishes P207C. Its bank 1 equivalent P2077 is well documented at GM, where the limit is given in percent and the scale runs backwards (95 % or more counts as low), and FCA cites P2077 for the 3.5L V6 manifold tuning valve; a bank 2 application would follow the same pattern. Ground faults can also kill other sensors on the shared 5 V circuit, so if several sensor codes appear together, look for the common reference first. P207D is the high-side fault.
P207C 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 P207C
- Check engine light (manufacturer-dependent)
- Other 5 V sensor codes at the same time
Common causes of P207C
- Most likelyBank 2 signal wire shorted to ground
- PossibleShared 5 V reference pulled down or open
- Less likelyInternal short in the bank 2 sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P207C 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. |
| 7C | The exact fault in that area. |
What to do next
- Note P207C 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 P207C
What does P207C mean?
P207C means "Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Low (Bank 2)". Low signal on the position feedback of the bank 2 tuning valve: the controller sees a value below the window it accepts. It is a generic code, so it means the same on every make.
Is it safe to drive with P207C?
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 P207C fail an emissions test?
Yes, it can. P207C 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 P207C 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 P207C 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.
