WARNING: This page is about a different variant/trim than selected.

P0192-00 (PCM (PYUL)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Fuel pressure sensor system: Low input
Detection condition	The specified period of time has elapsed while the fuel pressure sensor voltage is less than the standard.
Fail-safe	Stops the high pressure fuel pump. Inhibits the intake air flow. Inhibits engine-stop by i-stop control.
Vehicle status when DTCs are output	Not applicable
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC ) Perform the KOEO or KOER self test. (See DTC INSPECTION )
Inspection/action procedure	Proceed with the inspection/action in the order from Step 1 below. After part repair or replacement, perform the repeatability verification procedure and perform a DTC inspection. (See DTC INSPECTION ) If the DTC inspection indicates the same DTC again, go to the next step. Inspect the wiring harness (including connector/terminal) between the fuel pressure sensor and the PCM. Purpose/reason (possible cause) Malfunction in wiring harness (including connector/terminal) between fuel pressure sensor and PCM Referred to service information item (See CIRCUIT INSPECTION .) (See CONNECTOR INSPECTION .) Inspect the fuel pressure sensor. Purpose/reason (possible cause) Fuel pressure sensor malfunction Referred to service information item (See FUEL PRESSURE SENSOR INSPECTION .) Inspect high pressure fuel pump. Purpose/reason (possible cause) Malfunction in high pressure fuel pump Referred to service information item (See HIGH PRESSURE FUEL PUMP INSPECTION ) Replace the PCM. Purpose/reason (possible cause) PCM malfunction (no other possible malfunction considered) Referred to service information item (See PCM REMOVAL/INSTALLATION [H3T] )
