DTC Advanced Diagnostics: P0192, P0193 (2.0L Engine) (2024 2025)
DTC P0192 : Fuel Rail Pressure Sensor Circuit Low Voltage DTC P0193 : Fuel Rail Pressure Sensor Circuit High Voltage
General Description
The powertrain control module (PCM) monitors the sensor signal of the fuel rail pressure sensor. Failures in function caused by an open or short circuits in the electrical circuit can be detected with a pull-up resistor. If the fuel rail pressure sensor output voltage is a specified voltage for a set time, the PCM detects a malfunction and stores a DTC.

Possible Cause
The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
DTC: P0192
- Fuel rail pressure sensor PF line short to ground
- Fuel rail pressure sensor VCC1_5 line open
DTC: P0193
- Fuel rail pressure sensor PF line short to power
- Fuel rail pressure sensor PF line open
- Fuel rail pressure sensor SG9 line open
Common
- Fuel rail pressure sensor failure
- PCM internal circuit failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
