Monitor Description

WARNING: This page is about a different car, the 2021 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

Those DTCs are stored when a deviation from pressure sensor characteristics is detected.

The pressure sensors* are checked approximately 50 minutes after the engine switch is turned off. If the pressures detected by the pressure sensors* differ by a certain amount, the MIL is illuminated and a DTC is stored (2 trip detection logic).

HINT:

*: P106A-62 checks the canister pressure sensor and the manifold absolute pressure sensor. P106C-62 checks the canister pressure sensor and atmospheric pressure sensor.
Correct judgment may not be possible when the altitude is 4000 m (13120 ft.) or more.
