Mazda 3 Service Manual: Oil Pressure Switch Inspection [FS5 A EL]
CAUTION:
-
Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
On-Vehicle Inspection
1. Perform the following procedures.
a. Remove the aerodynamic under cover NO.2..
b. Disconnect the oil pressure switch connector.
2. Start the engine.
3. Inspect the continuity between the oil pressure switch terminal A and body GND.
-
If there is any malfunction, replace the oil pressure switch..
