Fluid Pressure Sensor/Switch: Testing and Inspection

OIL PRESSURE SWITCH INSPECTION [FS5A-EL]

CAUTION:
- Do not allow foreign material or water to penetrate the connector. Otherwise, it could cause poor contact and corrosion.

On-Vehicle Inspection Preparation

1. When performing the on-vehicle inspection, set the oil cooler out of the way.
a. Disconnect the oil cooler from the transaxle. Removal and Replacement
NOTE:
- Do not disconnect the oil hose and water hose from the oil cooler and transaxle because the engine is started when performing the on-vehicle inspection.

b. Suspend the oil cooler using rope to secure the disconnected oil cooler.






CAUTION:
- To prevent damage to the parts, do not pull the oil hose and water hose excessively.
- To prevent damage to the parts, do not twist the oil hose and water hose.
- To prevent part damage, do not allow parts to interfere with the cooling fan.

On-Vehicle Inspection

1. Remove the aerodynamic under cover. Service and Repair

2. Prepare for the on-vehicle inspection.

3. Disconnect the oil pressure switch connector.






4. Start the engine.

5. Measure continuity between oil pressure switch terminal A and GND.






- If there is any malfunction, replace the oil pressure switch. Service and Repair

Oil pressure switch continuity





Part Inspection

1. Apply air pressure of 400-440 kPa {4.08-4.48 kgf/cm2, 58.1-63.8 psi} to the oil pressure switch as shown in the figure.






2. Measure continuity between oil pressure switch terminal A and the thread area.






- If there is any malfunction, replace the oil pressure switch.
