What P2020 means
P2020 flags a bank 2 position signal that is electrically sound but does not fit what the flaps should be doing. On the CGFA hybrid V6 of the 2014 Touareg, Volkswagen triggers it when commanded and measured flap position are more than 40 % apart or the reported value leaves the 0–100 % window. Ford's summaries describe it as the bank 2 sensor travelling too far: the plates either miss the commanded position or the sensor reports travel beyond the normal stops, and four such events are needed. Because a sticking shaft, a broken lever or a vacuum fault looks the same to the sensor, P2020 often appears next to the stuck codes P2005 or P2007.
P2020 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyHard
- Typical labor1 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2020
- Check engine lamp on
- Reduced pull in the mid range or uneven idle
Common causes of P2020
- Most likelyBank 2 flap shaft sticking or carbon-fouled
- PossibleBroken lever or linkage between actuator and shaft
- PossibleWeak vacuum or leaking actuator diaphragm (vacuum systems)
- Less likelySensor shifted or adaptation missing after repair
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2020 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. |
| 20 | The exact fault in that area. |
What to do next
- Note P2020 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 P2020
What does P2020 mean?
P2020 means "Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 2)". P2020 flags a bank 2 position signal that is electrically sound but does not fit what the flaps should be doing. It is a generic code, so it means the same on every make.
Is it safe to drive with P2020?
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 P2020 fail an emissions test?
Yes, it can. P2020 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 P2020 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2020 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.
