Q: What does code P1405 mean?

Turbo Pressure Sensor Circuit. P1405 on Toyota vehicles indicates that the engine control module (ECM) has detected an abnormal signal from the turbo pressure sensor circuit, which monitors boost pressure in the intake system. The ECM compares the sensor's voltage output against expected values and flags the code when the signal falls outside the normal operating range.
