Refer to DTC P222611.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P222687 | Barometric Pressure Sensor "A" Missing Message | A communication malfunction between the atmospheric pressure sensor and main CPU of the ECM continues for 3 seconds or more. (ECM internal malfunction) (1 trip detection logic) | ECM | Comes on | DTC stored | SAE Code: P2226 |
| P222696 | Barometric Pressure Sensor "A" Component Internal Failure | A communication malfunction between the atmospheric pressure sensor and main CPU of the ECM continues for 3 seconds or more. (ECM internal malfunction) (1 trip detection logic) | ECM | Comes on | DTC stored | SAE Code: P2226 |
The ECM calculates the atmospheric pressure based on the output voltage of the atmospheric pressure sensor.
If it is judged that there is a communication malfunction between the atmospheric pressure sensor and main CPU of the ECM or there is an atmospheric pressure sensor internal malfunction, the ECM illuminates the check engine warning light and stores a DTC.
| Required Sensors/Components | Atmospheric pressure sensor (ECM) |
| Frequency of Operation | Continuous |
Connect the GTS to the DLC3.
Turn the ignition switch ON.
Turn the GTS 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.
Turn the ignition switch ON.
Turn the GTS on.
Wait 3 seconds or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the pending DTCs.
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: P222687 or P222696.
Check the DTC judgment result.
| GTS 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 |
If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system is malfunctioning.
Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.
(Select Powertrain in Health Check and then check the time stamp data.)
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.
Read freeze frame data using the GTS. 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.
Connect the GTS to the DLC3.
Turn the ignition switch ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the DTCs.
