1.Engine control system can quickly diagnose the faulty part by using the diagnostic tool.(Refer to "DTC guide")
(1) Self-diagnosis : Inspects and displays the DTC.
(2) Sensor data : Checks system input/output values.
(3) Forced operation : Checks system operation status
(4)Additional function : Controls other functions such as system option, zero point adjustment.
1. Remove the Oil Pressure & Oil Temperature Sensor.(Refer to Oil Pressure & Oil Temperature Sensor - "Removal")
2.After immersing the thermistor of the sensor into engine oil, measure resistance between the sensor terminals 1 and 4.

1.Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
2.Remove the intake manifold.(Refer to Engine Mechanical System - "Intake Manifold")
3. After disconnectting the oil pressure & oil temperature sensor connector (A), remove the oil pressure & oil temperature sensor (B).
Tightening torque :35.3 - 38.2 N.m (3.6 - 3.9 kgf.m, 26.0 - 28.2 lb-ft)
1.Install in the reverse order of removal.
• Install the component to the specified torques.
• Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
• Apply sealant to thread when refitting.
