INSPECTION

1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR

INSPECT ENGINE COOLANT TEMPERATURE SENSOR

(a) Using an ohmmeter, measure the resistance between the terminals.

Standard resistance

If the result is as specified, do not replace the engine coolant temperature sensor
If the result is not as specified, replace the engine coolant temperature sensor.

NOTICE: In case of checking the engine coolant temperature sensor in water, do not allow water to go into the terminals. After checking, dry the engine coolant temperature sensor.

INSTALLATION

Shift Solenoid "E" Performance (Shift Solenoid Valve SR)
SYSTEM DESCRIPTION The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd, 4th or 5th gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical problems of the shift solenoid valves, valve b ...

All Doors cannot be Locked / Unlocked at Once
DESCRIPTION The body ECU receives a switch signal from the master switch, the door control switch, the driver door key cylinder and the passenger door key cylinder and then drives the door lock motor. WIRING DIAGRAM INSPECTION PROCEDURE 1 INSPECT FUSE (ECU-B) Remove ECU-B fuse f ...

System Voltage
MONITOR DESCRIPTION The battery supplies electricity to the ECM even when the ignition switch is off. This power allows the ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls below a minimum level, these memories are cleared and the ...
