Sedona EX V6-3.5L (2002)
Oil Pressure Sender: Testing and Inspection
Oil pressure switch
1. If "OIL PRESSURE" indicating lamp lights when ignition switch is set to "ON" and goes out when engine is started and runs at idle, then
everything is in order. If "OIL PRESSURE" lamp does not light when ignition switch is set to "ON", check switch, lamp and wiring.
2. If there is current flow when ignition switch is set to "ON" and if there is no current flow when engine is running at idle, switch is good. If switch
is good, check lamp and wiring.
Operating pressure of oil pressure switch 19.6 - 39.2 kPa (0.2 - 0.4 kg/cm2 , 2.84 - 5.69 psi)
3. Using the special tool, tighten the switch to the specified torque (09260-32000).
Notice: Do not tighten the oil pressure switch to the excessive torque.
Tightening torque
Oil pressure switch and sensor assembly: 8 - 12 Nm (80 - 120 kg-cm, 5.91 - 8.85 ft. lbs.)
Inspection
1. Check the continuity between the terminal and the body with an ohmmeter. If there is no continuity, replace the oil pressure switch.
2. Check the continuity between the terminal and the body when the fine wire is pushed. If there is continuity even when the fine wire is pushed,
replace it.
3. If there is no continuity when a 0.5 kg/cm2 vacuum is applied through the oil hole, the switch is operating properly. Check that air doesn't leak. If
air leaks, the diaphragm is broken. Replace the switch.
