P107A2A |
Fuel Rail Pressure Sensor (Low) Signal Stuck in Range |
When the target fuel pressure for the low pressure side changes, the change in the fuel pressure sensor (for low pressure side) value is abnormal (2 trip detection logic). |
|
Comes on |
DTC stored |
SAE Code: P107B |
|
P107A64 |
Fuel Rail Pressure Sensor (Low) Signal Plausibility Failure |
When the fuel pump on the low pressure side is operated at maximum speed when the engine is stopped at vehicle speed of 45 km/h (28 mph) or more, the low pressure side fuel pressure is higher or lower than threshold (2 trip detection logic). |
|
Comes on |
DTC stored |
SAE Code: P107B |
MONITOR DESCRIPTION
Fuel Pressure Sensor Stuck Monitor
If the fuel pressure sensor (fuel delivery pipe with sensor sub-assembly) (for low pressure side) value does not follow the change in the target low pressure side fuel pressure, it is judged as a malfunction. If this malfunction is detected in 2 consecutive driving cycles, the ECM will illuminate the MIL and store DTC P107A2A.
Fuel Pressure Sensor Correlation Monitor
If the fuel pressure sensor (fuel delivery pipe with sensor sub-assembly) (for low pressure side) value is less than or higher than the threshold value when the fuel pump on the low pressure side is operated at maximum speed when the engine is stopped at vehicle speed of 45 km/h (28 mph) or more, it is judged as a malfunction has occurred. If this malfunction is detected for 2 consecutive driving cycles, the ECM will illuminate the MIL and store DTC P107A64.

CAUTION / NOTICE / HINT
NOTICE:
-
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.

-
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:
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 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.

(5) Start the engine.
(6) After the engine has stopped on its own, turn the power switch off.
HINT:
If the engine does not stop naturally, perform direct injection by racing the engine to reduce the fuel pressure [Fuel Pressure (High)] and stop the engine.
(7) Turn the power switch on (IG).
(8) Turn the Techstream on.
