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

DTC P0192:00	Fuel pressure sensor circuit low input
DETECTION CONDITION	If the input voltage at the PCM terminal 1CA is less than 0.16 V for 5 s , the PCM determines that the fuel pressure sensor circuit is low. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	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 wiring harness between the following terminals: Fuel pressure sensor terminal C-PCM terminal 1BJ Fuel pressure sensor terminal B-PCM terminal 1CA Fuel pressure sensor signal circuit and ground circuit are shorted to each other Fuel pressure sensor malfunction PCM malfunction

CAUTION:

Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
