DTC P0190-11: Fuel Rail Pressure Sensor "A" Circuit Short to Ground [10/2015 - ]: Procedure
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus RC 300, 2023 Lexus RC 300, 2022 Lexus RC 300, 2021 Lexus RC 300, and 2020 Lexus RC 300. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR (FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE) - ECM)
- Disconnect the fuel pressure sensor (for high pressure side) connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E2-1 (VC) - F67-136 (VCPR) Always Below 1 Ω E2-3 (PR) or F67-103 (PR) - Body ground and other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 2
- CHECK TERMINAL VOLTAGE (POWER SOURCE OF FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE))
*a Front view of wire harness connector
(to Fuel Pressure Sensor (for High Pressure Side))- Disconnect the fuel pressure sensor (for high pressure side) connector.
- Turn the engine switch on (IG).
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition E2-1 (VC) - E2-2 (E2) Engine switch on (IG) 4.75 to 5.25 V Result
Proceed to OK NG HINT:
Perform "Inspection After Repair" after replacing the fuel pressure sensor (for high pressure side).
Refer to INITIALIZATION [10/2015 - 10/2018] , or refer to INITIALIZATION [10/2018 - 11/2019] , or refer to INITIALIZATION [11/2019 - ]
Result:
OK
REPLACE FUEL DELIVERY PIPE SUB-ASSEMBLY (FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE)). Refer to REMOVAL [10/2015 - ]
Result:
NG
REPLACE ECM. Refer to REMOVAL [10/2015 - ]
