- How the car detects it
- P34C3 completes the sensor group of actuator B: on bank 2, sensor A watching the exhaust-side actuator puts out a voltage beyond its permitted range. A broken sensor ground, an open signal path or contact with a feed line are the usual causes. No manufacturer publishes P34C3. Mercedes-Benz, whose CAMTRONIC V8 uses neighbouring codes on this bank (P34C1, P34C2), lists no high fault, and the 2022 Mitsubishi Outlander has no electric exhaust actuator at all – its exhaust camshaft is shifted through an oil control solenoid that the fail-safe fixes in its reference position together with the electric intake motor. Until the cause is found the bank 2 exhaust adjustment stays in its default state, so drivers mainly see the warning lamp. Bank 1: P34BF.
