A25A-FKS (ENGINE CONTROL): SFI SYSTEM: P106A62,P106C62; Evaporative Emission System Pressure / Intake Air Pressure Signal Compare Failure; 2021 - 2024 MY RAV4 RAV4 HV [08/2020

Those DTCs are designed to detect a deviation in the output characteristics of a pressure sensor.

MONITOR DESCRIPTION

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

The pressure sensors* are checked approximately 50 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).

CONFIRMATION DRIVING PATTERN

HINT:

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Start the engine and idle for 10 seconds or more [A].
Turn the ignition switch off.
Leave the ignition switch off for 55 minutes [B].
Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Powertrain / Engine / Trouble Codes [C].
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P106A62 or P106C62.

Check the DTC judgment result.

Techstream Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions

HINT:

If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system is malfunctioning.
If the judgment result is INCOMPLETE, perform steps [A] through [C] again.
[A] to [C]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

HINT:

Refer to "Data List / Active Test" [Atmospheric Pressure, Intake Manifold Absolute Pressure and Vapor Pressure Pump].
Click here
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

Powertrain > Engine > Trouble Codes

If any DTCs other than P106A62 and/or P106C62 are output, troubleshoot those DTCs first.

Powertrain > Engine > Clear DTCs

(d) Enter the following menus: Powertrain / Engine / Data List / Atmospheric Pressure, Vapor Pressure Pump and Intake Manifold Absolute Pressure.

Powertrain > Engine > Data List

(e) Confirm that the difference between Intake Manifold Absolute Pressure and Vapor Pressure Pump is 7.23 kPa (1.04 psi) or less.

(f) Confirm that the difference between Atmospheric Pressure and Vapor Pressure Pump is 10 kPa (1.45 psi) or less.
