P106A
2ZR-FXE ENGINE CONTROL: SFI SYSTEM: P106A: Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation
P106A - Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation
DESCRIPTION
HINT
*: Data List Name
MONITOR DESCRIPTION
Tis DTC is designed to detect a deviation in the output characteristics of a pressure sensor.
The pressure of the canister pressure sensor and manifold absolute pressure sensor is monitored 55 minutes after the power switch is turned off. If there is a difference in the pressures, the MIL is illuminated (2 trip detection logic).
HINT
Correct judgment may not be possible when the altitude is 13124 ft (4000 m) or more.

TYPICAL MALFUNCTION THRESHOLDS
CONFIRMATION DRIVING PATTERN
1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG) and turn the Techstream on.
3. Clear the DTCs (even if no DTCs are stored, perform the Clear DTC procedure) Reading and Clearing Diagnostic Trouble Codes [A].
4. Put the engine in inspection mode (maintenance mode) Component Tests and General Diagnostics.
5. Start the engine and Idle for 10 seconds [B]
6. Turn the power switch off and wait for 30 seconds.
7. Leave the power switch off for 55 minutes [C]
8. Connect the Techstream to the DLC3.
9. Turn the power switch on (IG) and turn the Techstream on.
10. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].
11. 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.
12. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
13. Input the DTC: P106A.
14. Check the DTC judgment result.
HINT
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [A] through [D].
15. If no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
INSPECTION PROCEDURE
HINT
- 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
- Refer to "Data List / Active Test" [Vapor Pressure Pump and MAP] Data List / Active Test.
PROCEDURE
1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO P106A)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) Read the DTCs.
Result
HINT
If any DTCs other than P106A are output, troubleshoot those DTCs first.
B -- GO TO DTC CHART SFI System
A -- Continue to next step.
2. READ VALUE USING TECHSTREAM (VAPOR PRESSURE PUMP AND MAP)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Vapor Pressure Pump and MAP.
(e) Compare the Vapor Pressure Pump and MAP data from the Data List with day's atmospheric pressure*.
HINT
- *: Standard atmospheric pressure is 101 kPa (760 mmHg) at sea level. The atmospheric pressure decreases by approximately 1 kPa (7.5 mmHg) for every 100 m of elevation increase. Atmospheric pressure is also affected by weather conditions. The Atmosphere pressure listed in the Data List cannot be used as a reference for this check.
- If you do not know the atmospheric pressure refer to the Vapor Pressure Pump value of other vehicles in the workshop and check the difference in pressure.
Result
B -- REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR
A -- Continue to next step.
3. REPLACE CANISTER ASSEMBLY
(a) Replace the canister assembly Removal.
NEXT -- CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
4. REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR
(a) Replace the manifold absolute pressure sensor Removal.
NEXT -- Continue to next step.
5. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG) and the Techstream on.
(c) Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / MAP and Vapor Pressure Pump.
(d) Confirm that the difference between Vapor Pressure Pump and MAP are 3.5 kPa (+/- 26.25 mmHg) or less.
