DTC P0192-00: Fuel Pressure Sensor Circuit Low Input: Outline

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

DTC P0192:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Fuel pressure sensor circuit low input
Detection condition	If the input voltage at the PCM terminal 1W is less than 0.51 V for 5 s, the PCM determines that the fuel pressure sensor circuit is low.
Fail-safe	Stops high pressure fuel pump control Limits intake air amount
Possible cause	Fuel pressure sensor connector or terminals malfunction PCM connector or terminals malfunction Short to ground in any of the following fuel pressure sensor circuits. Power supply circuit Signal circuit Short circuit in fuel pressure sensor signal circuit and ground circuit Fuel pressure sensor malfunction High pressure fuel pump malfunction PCM malfunction
