DESCRIPTION
DTC
NO.
DTC DETECTION CONDITION
TROUBLE AREA
P106A
The pressure detected by the canister pressure sensor (Vapor Pressure
Pump*) and the pressure detected by the manifold absolute pressure
sensor (MAP*) differ by 7 kPa (54 mmHg) or more
(2 trip detection logic)
Canister pressure
sensor (canister
pump module)
Manifold absolute
pressure sensor
P106B
The pressure detected by the canister pressure sensor (Vapor Pressure
Air Pump2 Pressure (Absolute)*) differ by 6.98 kPa (52 mmHg) or more
(2 trip detection logic)
Canister pressure
sensor (canister
pump module)
Air switching
valve (Bank 1)
Air switching
valve (Bank 2)
HINT:
This DTC is stored when a deviation from pressure sensor characteristics is detected.
The pressure sensors* are checked 55 minutes after the ignition 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:
Connect the Techstream to the DLC3.
1.
Turn the ignition switch ON and turn the Techstream on.
2.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure)
[A].
3.
Start the engine.
4.
Idle the engine for 10 seconds [B].
5.
Turn the ignition switch off.
6.
Soak the vehicle for 55 minutes [C].
7.
Turn the ignition switch ON and turn the Techstream on.
8.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
9.
Read the pending DTCs [D].
10.
If a pending DTC is output, the system is malfunctioning.
HINT:
If no pending DTC is output, perform the steps below.
11.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
12.
Input the DTC: P106A or P106B.
13.
Check the DTC judgment result.
