P2435AIR System Air Flow/Pressure Sensor Circuit (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2435 is the bank 2 version of the basic signal fault of the secondary air pressure sensor. It exists only where each cylinder bank has its own air path with a sensor, for instance Audi's R8 V10 with the bank 2 sensor G610. GM lists P2435 among its AIR pressure sensor codes in the 2018 tables, but the detailed rows there describe engines with one air path that use only the bank 1 codes, so no threshold is published for P2435 itself. By analogy with GM's P2430, the computer would look for a frozen or missing signal while the pump runs. One pump usually feeds both banks, so a bank 2-only code points to the sensor, its plug or its wiring on that side. P2430 is the bank 1 twin.
- What you may notice
- Check engine lamp after cold starts

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
