MONITOR DESCRIPTION
The ECM monitors the status of the GPF using 2 exhaust temperature sensors, installed to the inlet and outlet.
The No. 1 exhaust gas temperature sensor sends a signal of the GPF upstream exhaust temperature to the ECM.
The No. 2 exhaust gas temperature sensor sends a signal of the GPF downstream exhaust temperature to the ECM.
The ECM detects loss of function of the GPF by converting the temperature change into an area after monitoring the exhaust temperature upstream and downstream of the GPF from the time the engine is started until the exhaust temperature downstream of the GPF reaches 80°C or more after 5 hours or more have passed since the last engine shutdown. When the minimum intake air temperature during monitoring is 10°C (50°F) and the value obtained by dividing the GPF upstream exhaust temperature area by the GPF downstream exhaust temperature area is less than 2.5, the ECM determines loss of function of the GPF and illuminates the MIL and stores a DTC.
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 procedure.
·When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
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.
With the engine stopped, leave the vehicle as is for 3 hours or more.
Turn the ignition switch to ON.
Turn the GTS on.
Put the engine in Inspection Mode (for measuring Exhaust Gas).
Start the engine.
Idle the engine for 15 minutes or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the pending DTCs.
- HINT:
-
If a pending DTC is output, the system is malfunctioning.
CAUTION / NOTICE / HINT
- NOTICE:
- ·
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.
- HINT:
-
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.
