NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
10. INSPECT TRANSMISSION WIRE (OIL PRESSURE SWITCH)
(a) Disconnect the oil pressure switch connector Removal.
(b) Disconnect the transmission wire connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPAIR OR REPLACE TRANSMISSION WIRE Removal
OK -- REPLACE OIL PRESSURE SWITCH Disassembly
