DTC Detecting Condition and Trouble Area
NOTE
After reprogramming of ECM is executed, if the DTC P0601 and/or P0602 are indicated, it is possible
that the reprogramming of ECM is not completed correctly.
DTC Confirmation Procedure
1) With ignition switch OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC by using scan tool.
3) Start engine and run it at idle if possible.
4) Check DTC.
DTC detecting condition Trouble area
DTC P0532:
Output voltage of A/C refrigerant pressure sensor is lower than 0.2
V for 5 sec.
(1 driving cycle detection logic but MIL does not light up)
• A/C refrigerant pressure sensor and/or its
circuit
• ECM
DTC P0533:
Output voltage of A/C refrigerant pressure sensor is higher than
4.93 V for 5 sec.
(1 driving cycle detection logic but MIL does not light up)
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed? Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2 A/C refrigerant pressure sensor and its circuit check
1) Check A/C refrigerant pressure sensor and its circuit for
condition referring to “A/C Refrigerant Pressure Sensor
and Its Circuit Inspection in Section 7B”.
Is it in good condition?
Substitute a known-
good ECM and recheck. Repair or replace
defective parts.
