Fuel Rail Pressure Sensor "A" Circuit Short to Battery or Open |
The fuel pressure sensor (for high pressure side) output voltage is higher than 4.9 V for 3 seconds or more (1 trip detection logic). |
|
Comes on |
DTC stored |
SAE Code: P0193 |
HINT:
When this DTC is output, check the fuel pressure (for high pressure side) in the Data List. Enter the following menus: Powertrain / Engine / Data List / Fuel Pressure (High).
|
DTC No. |
Fuel Pressure (High) |
Malfunction |
|---|---|---|
|
P019015 |
Approximately 33000 kPag or higher |
|
If the Data List values are normal, it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
MONITOR DESCRIPTION
This DTC is stored if the fuel pressure sensor (for high pressure side) output voltage is out of the standard range due to an open or short in the sensor circuit.
Example:
If the fuel pressure sensor (for high pressure side) output voltage is higher than 4.9 V for 3 seconds or more, the ECM will illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream 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.
- Start the engine [A].
- Idle the engine for 10 seconds [B].
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Trouble Codes [C].
-
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P019015.
-
Check the DTC judgment result.
Techstream Display
Description
NORMAL
- DTC judgment completed
- System normal
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system has a malfunction.
- If the judgment result is INCOMPLETE, perform steps [B] through [C] again.

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.
PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR |
|
*a |
Front view of wire harness connector (to Fuel Pressure Sensor (for High Pressure Side)) |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the fuel pressure sensor (for high pressure side) connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
