DESCRIPTION
The fuel trim is related to the feedback compensation value, not to the basic injection duration. The fuel trim consists of both the short-term and long-term fuel trims.
The short-term fuel trim is fuel compensation that is used to constantly maintain the air fuel ratio at stoichiometric levels. The signal from the air fuel ratio sensor (sensor 1) indicates whether the air fuel ratio is rich or lean compared to the stoichiometric ratio. This triggers a reduction in the fuel injection volume if the air fuel ratio is rich and an increase in the fuel injection volume if lean.
Factors such as individual engine differences, wear over time and changes in operating environment cause short-term fuel trim to vary from the central value. The long-term fuel trim, which controls overall fuel compensation, compensates for long-term deviations in the fuel trim from the central value caused by the short-term fuel trim compensation.

When DTC P017100 is stored, the actual air fuel ratio is on the lean side. When DTC P017200 is stored, the actual air fuel ratio is on the rich side.
·If the vehicle runs out of fuel, the air fuel ratio is lean and DTC P017100 may be stored. The MIL is then illuminated.
·When DTC P117000 or P117B00 is output, it may not be possible to precisely determine whether the port injection or the direct injection is malfunctioning, depending on the conditions. In this case, perform an Active Test (Control the Injection Mode) to determine which injection system is malfunctioning.
MONITOR DESCRIPTION
Under closed loop fuel control, fuel injection volumes that deviate from those estimated by the ECM cause changes in the long-term fuel trim compensation value. The long-term fuel trim is adjusted when there are persistent deviations in the short-term fuel trim values. Deviations from the fuel injection volumes estimated by the ECM also affect the average fuel trim learned value, which is a combination of the average short-term fuel trim (fuel feedback compensation value) and the average long-term fuel trim (learned value of the air fuel ratio). If the average fuel trim learned value exceeds the malfunction thresholds, the ECM interprets this as a malfunction of the fuel system and stores a DTC.
Example:
The average fuel trim learned value is +35% or higher, or -35% or less, the ECM interprets this as a fuel system malfunction.

CONFIRMATION DRIVING PATTERN
- HINT:
- ·
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
·Permanent misfire and fuel system DTCs can only be cleared when performing the universal trip driving pattern when no malfunction is detected.
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 [A].
Turn the GTS on.
Put the engine in Inspection Mode (Maintenance Mode).
Start the engine and warm it up until the engine coolant temperature 75°C (167°F) or higher with all the accessories switched off [B].
With the engine warmed up, idle the engine for 5 minutes or more [C].
With the engine running, drive the vehicle at a speed between 60 and 100 km/h (37 and 62 mph) for 5 minutes or more [D].
- CAUTION:
-
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- HINT:
-
If the engine stops, further depress the accelerator pedal to restart the engine.
Stop the vehicle, and idle the engine for 5 minutes or more [E].
Enter the following menus: Powertrain / Engine / Trouble Codes [F].
Read the pending DTCs.
- HINT:
-
If a pending DTC is output, the system is malfunctioning.
WIRING DIAGRAM

CAUTION / NOTICE / HINT
- NOTICE:
- ·
Inspect the fuses for circuits related to this system before performing the following procedure.
·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.
- HINT:
- ·
Sensor 1 refers to the sensor closest to the engine assembly.
·Sensor 2 refers to the sensor farthest away from the engine assembly.
·A low air fuel ratio sensor (sensor 1) current could be caused by a rich air fuel mixture. Check for conditions that would cause the engine to run rich.
·A high air fuel ratio sensor (sensor 1) current could be caused by a lean air fuel mixture. Check for conditions that would cause the engine to run lean.
·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.
