Result
Proceed to OK NG
Result:
NG
GO TO AMBIENT TEMPERATURE DISPLAY SYSTEM. Refer to Ambient Temperature Display System [11/2022 - ]
Result:
OK
See step 2
- Read the Data List according to the display on the GTS.
- READ VALUE USING GTS
- Read the Data List according to the display on the GTS.
Powertrain > Engine > Data List
Tester Display Measurement Item Range Normal Condition Diagnostic Note Coolant Temperature Engine coolant temperature Min.: -40°C (-40°F), Max.: 140°C (284°F) 75 to 100°C (167 to 212°F): After warming up This is the engine coolant temperature.
HINT:- After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F).
- After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.
- If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.
- Check if the engine overheats if the value indicated is higher than 135°C (275°F).
Powertrain > Engine > Data List
Tester Display Coolant Temperature OK

Tester Display Regulator Pressure Sensor - Install a manifold gauge set.
- Read the manifold gauge pressure when the following conditions are met.
- Prepare the vehicle according to the table below.MEASUREMENT CONDITION:
Item Condition Vehicle doors Fully open Temperature setting MAX COLD Blower speed HI A/C switch On Recirculation/fresh switch RECIRCULATION Interior temperature 25 to 35°C (77 to 95°F)
Standard Pressure
Low pressure side
150 to 250 kPa (1.5 to 2.5 kgf/cm2 , 22 to 36 psi)
High pressure side
1370 to 1570 kPa (14 to 16 kgf/cm2 , 199 to 228 psi)
- Prepare the vehicle according to the table below.
- Compare the values displayed in the Data List and on the manifold gauge.
OK
The values displayed in the Data List and on the manifold gauge match.
Result
Proceed to OK NG
Result:
OK
GO TO ON-VEHICLE INSPECTION (CHECK REFRIGERANT PRESSURE USING GAUGE). Refer to ON-VEHICLE INSPECTION [09/2021 - ]
Result:
NG
REPLACE AIR CONDITIONER PRESSURE SENSOR. Refer to REMOVAL [09/2021 - ]
- Read the Data List according to the display on the GTS.
