Oil Pressure Switch B

  1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
  2. Remove the front under cover No. 2. (See FRONT UNDER COVER NO. 2 REMOVAL/INSTALLATION .)
  3. Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.
  4. Drain the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT .)
  5. 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.
  6. Remove the oil strainer. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
  7. Remove the oil strainer O-ring. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
  8. Insert a precision flathead screwdriver and move it in the direction of the arrow to disconnect the oil pressure switch B connector as shown in the figure.
    CAUTION:
    • Do not scratch the oil pressure switch B and oil pressure switch connector B with the precision flathead screwdriver.
    • When disconnecting connectors, grasp the connectors, not the wiring harnesses. Otherwise, the wiring harnesses may be pulled out of the connector causing poor contact.
