DTC Confirmation Procedure

1) Start engine and operate A/C for 10 sec. or more.

DTC Troubleshooting


1. Was "Engine and Emission Control System Check" performed?
YES
Go to Step 2.
NO
Go to Engine and Emission Control System Check Engine and Emission Control System Check.
2. A/C refrigerant pressure sensor power supply circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect connector from A/C refrigerant pressure sensor.
Check for proper terminal connection to A/C refrigerant pressure sensor connector.
If connections are OK, check that voltage between "A1" and "A3" circuits are 5 V with ignition mode of keyless push start system in "ON".
Are they in good condition?
YES
Go to Step 5.
NO
Go to Step 3.
3. A/C refrigerant pressure sensor ground circuit check
Check that voltage between "A1" circuit and ground is 5 V.
Is it in good condition?
YES
Repair or replace "A3" circuit.
If this DTC is detected again, replace ECM and recheck DTC. Service and Repair
NO
Go to Step 4.
4. A/C refrigerant pressure sensor power supply circuit check
Push engine switch to change ignition mode to "OFF".
Disconnect "C01" and "E01" connectors.
Check for proper terminal connection to "C01" and "E01" connectors.
If connections are OK, check the following points.
Resistance of "A1" circuit: less than 1
Resistance of "A1" circuit between A/C refrigerant pressure sensor connector and ground: infinity
Resistance of between "A1" circuit terminal and other terminal at A/C refrigerant pressure sensor connector: infinity
Voltage of "A1" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Replace ECM and recheck DTC. Service and Repair
NO
Repair or replace defective wire harness.
5. A/C refrigerant pressure sensor signal circuit check
Push engine switch to change ignition mode to "OFF".
Disconnect "C01" and "E01" connectors.
Check for proper terminal connection to "C01" and "E01" connectors.
If connections are OK, check the following points.
Resistance of "A2" circuit: less than 1
Resistance of "A2" circuit between A/C refrigerant pressure sensor connector and ground: infinity
Resistance of between "A2" circuit terminal and other terminal at A/C refrigerant pressure sensor connector: infinity
Voltage of "A2" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Go to Step 6.
NO
Repair or replace defective wire harness.
6. A/C refrigerant pressure sensor check
Check A/C refrigerant pressure sensor. Testing and Inspection
Is it in good condition?
YES
Replace ECM and recheck DTC. Service and Repair
NO
Replace A/C refrigerant pressure sensor.
