Refer to DTC P245211.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Note |
|---|---|---|---|---|---|
| P245215 | Particulate Filter Pressure Sensor "A" Circuit Short to Battery or Open | The output voltage from the differential pressure sensor is higher than 4.835 V for 3 seconds or more (1 trip detection logic). | ·
Open or short in differential pressure sensor circuit ·
Differential pressure sensor ·

Does not come on | SAE Code: P2455 |
When a DTC is output, check the Data List item "Particulate Filter Differential Pressure Bank1" using the GTS.
| DTC No. | Particulate Filter Differential Pressure Bank1 | Malfunction |
|---|---|---|
| P245215 | 100 kPa [14.5 psi] or higher | ·
Short in VCPX circuit to PEX circuit ·
Open in PEX circuit ·
Open in EPEX circuit |
If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
In order to detect abnormality in the differential pressure sensor, the ECM always monitors the output voltage from the sensor. When the sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the sensor circuit.
Example:
When the sensor output voltage is higher than 4.835 V for 3 seconds or more, the ECM stores a DTC.
| Frequency of Operation | Continuous |
Connect the GTS to the DLC3.
Turn the ignition switch to 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 to ON.
Turn the GTS on.
Put the engine in Inspection Mode (Maintenance Mode).
Start the engine and wait 5 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: P245215.
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 shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
Vehicle Control History may be stored in the hybrid vehicle control ECU 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, 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.
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
Disconnect the differential pressure sensor connector.
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| C140-3 (VC) - C140-1 (E2) | Ignition switch ON | 4.75 to 5.25 V |
| C140-2 (PEX) - C140-1 (E2) | Ignition switch ON | 0.5 to 1.0 V |
Turn the ignition switch off and wait for at least 30 seconds.
Measure the resistance according to the value(s) in the table below.
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| C140-3 (VC) - C140-2 (PEX) | Ignition switch off | 190 to 210 kΩ |
