What P2023 means
P2023 is meant for a bank 2 flap position signal that briefly drops out or jumps without staying out of range long enough for P2021 or P2022. No manufacturer documents this code publicly; Ford's V-engine summaries stop at low, high and over-travel for bank 2, and Volkswagen's Touareg tables skip it. The closest published analogue is P2018 on bank 1, which Mitsubishi lists for the PR25DD-engined Outlander as a two-trip fault with warning lamp. CARB's rules for comprehensive components require circuit faults of emission-related inputs such as variable runner systems to be detected, so a calibration may use P2023 for unstable feedback. In practice it points to a loose connector, a chafed loom on the hot side of the engine or a worn sensor.
P2023 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2023
- Warning lamp appears now and then
- Usually no change in how the engine drives
Common causes of P2023
- Most likelyBank 2 sensor plug with loose or corroded contacts
- PossibleHarness rubbing through near exhaust or valve cover
- Less likelyWorn bank 2 position sensor giving dropouts
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2023 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. |
| 23 | The exact fault in that area. |
What to do next
- Note P2023 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 P2023
What does P2023 mean?
P2023 means "Intake Manifold Runner Position Sensor/Switch Circuit Intermittent (Bank 2)". P2023 is meant for a bank 2 flap position signal that briefly drops out or jumps without staying out of range long enough for P2021 or P2022. It is a generic code, so it means the same on every make.
Is it safe to drive with P2023?
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 P2023 fail an emissions test?
Yes, it can. P2023 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 P2023 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2023 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
