DTC P0193:00 (PCM, VIN Y) DIAGNOSTIC PROCEDURE

STEP	INSPECTION	RESULTS	ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE: Recording can be facilitated using the screen capture function of the PC. Record the FREEZE FRAME DATA/snapshot data on the repair order.	-	Go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	DETERMINE IF HIGH FUEL PRESSURE SENSOR OR WIRING HARNESS MALFUNCTION Access the FUEL_PRES PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .) Verify the FUEL_PRES PID value. Is the FUEL_PRES PID value 5 V or B+?	Yes	Go to Step 7.
3		No	Go to the next step.
4	INSPECT HIGH FUEL PRESSURE SENSOR CONNECTOR CONDITION Switch the ignition off. Disconnect the high fuel pressure sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
4		No	Go to the next step.
5	INSPECT PCM CONNECTOR CONDITION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
5		No	Go to the next step.
6	INSPECT HIGH FUEL PRESSURE SENSOR Reconnect all disconnected connectors. Inspect the high fuel pressure sensor. (See HIGH FUEL PRESSURE SENSOR INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the fuel distributor, then go to Step 10. (See FUEL INJECTOR REMOVAL/INSTALLATION [VIN Y] .)
6		No	Go to Step 10.
7	DETERMINE IF HIGH FUEL PRESSURE SENSOR SIGNAL CIRCUIT OR HIGH FUEL PRESSURE SENSOR GROUND CIRCUIT MALFUNCTION Switch the ignition off. Disconnect the high fuel pressure sensor connector. Access the FUEL_PRES PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .) Verify the FUEL_PRES PID value. Is the FUEL_PRES PID value 5 V or B+?	Yes	Go to the next step.
7		No	Go to Step 9.
8	INSPECT HIGH FUEL PRESSURE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT Verify that the high fuel pressure sensor connector is disconnected. Switch the ignition off. Disconnect the PCM connector. Inspect for continuity between high fuel pressure sensor terminal C (wiring harness-side) and PCM terminal 1BO (wiring harness-side). Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between high fuel pressure sensor terminal C and PCM terminal 1BO. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to power supply. Go to Step 10.
8		No	Refer to the wiring diagram and verify whether or not there is a common connector between high fuel pressure sensor terminal C and PCM terminal 1BO. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 10.
9	INSPECT HIGH FUEL PRESSURE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the high fuel pressure sensor connector is disconnected. Switch the ignition off. Disconnect the PCM connector. Inspect for continuity between the following terminals (wiring harness-side): High fuel pressure sensor terminal E-PCM terminal 1CI High fuel pressure sensor terminal A-PCM terminal 1CN Is there continuity?	Yes	Replace the fuel distributor, then go to the next step. (See FUEL INJECTOR REMOVAL/INSTALLATION [VIN Y] .)
9		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: High fuel pressure sensor terminal E-PCM terminal 1CI High fuel pressure sensor terminal A-PCM terminal 1CN If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to the next step.
10	VERIFY DTC TROUBLESHOOTING COMPLETED Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC .) Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST .) Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [VIN Y] .) Go to the next step.
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE .)
11		No	DTC troubleshooting completed.
