Fluid Pressure Sensor/Switch: Service and Repair
OIL PRESSURE SWITCH REMOVAL/INSTALLATION [FW6A-EL]
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 soiling could spatter and get into the eyes.
CAUTION:
- If the oil pressure switch has been replaced, perform initial learning. Programming and Relearning
- Do not place the control valve body connector pointed downward as the control valve body connector part and sensor could be damaged. If the servicing can only be performed by pointing the control valve body connector downward, spread a large quantity of cloth or sponges on a table and place the control valve body connector part and sensor on the table so that they do not directly contact the table.

6. Remove the oil pan.
CAUTION:
- To avoid damaging the control valve body, if there is a large amount of foreign material at the bottom of the oil pan when the oil pan is removed, replace the oil strainer with a new one.
- If there is not a large amount of foreign material at the bottom of the oil pan, the oil strainer does not have to be replaced.
NOTE:
- Always use new oil pan installation bolts when re-installing the oil pan because the oil pan installation bolts cannot be reused.
