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 the maximum during a fuel cut, 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 (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 (Fuel Cut)
If the fuel pressure sensor (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 the maximum during a fuel cut, 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
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.
