OIL PRESSURE SWITCH REPLACEMENT [CW6A-EL]

id0517l1112700

Warning
•  A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.
•  Always wear protective eye wear when using the air compressor. If the air compressor is used, any particles of dirt or sludge could spatter and get into the eyes.
Caution
•  Always perform the initial learning after replacing the oil pressure switch. (See INITIAL LEARNING [CW6A-EL].)
•  Do not apply excessive force to the coupler component wiring harness.
•  Be careful that the edge of the oil pressure switch and the ATF temperature sensor bracket does not damage the insulation of the coupler component wiring harness or the surrounding parts. If the insulation of the wiring harness is damaged, replace the coupler component. (See COUPLER COMPONENT REMOVAL/INSTALLATION [CW6A-EL].)
•  Touching the ATF temperature sensor element or the lead wires by hand may cause a malfunction. When handling the coupler component, do not touch the ATF temperature sensor element or the lead wires.
