Accent GS Coupe L4-1495cc 1.5L SOHC MFI (1999)
Oil Pressure Sender: Service and Repair
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.
Pressure of oil switch operation: 14.71-29.42 kPa (0.15-0.3 kg/cm2, 2.1-4.3 psi)
3. Using the special tool (09260-32000), tighten the switch to the specified torque.
NOTE: Do not overtorque the oil pressure switch
Tightening torque:
Oil pressure switch and sender assembly: 8-12 Nm (80-120 kg.cm, 5.8-8.7 ft. lbs.)
Oil pressure switch adaptor: 13-15 Nm (130-150 kg.cm, 9.6-11 ft. lbs.)
INSPECTION
1. Check the continuity between the terminal and the body with an ohmmeter.
If there is noncontinuity, replace the oil pressure switch.
2. Check the continuity between the terminal and the body when the fine wedge is pushed. If there is continuity even when the fine wedge is pushed,
replace it.
3. Or, if there is non continuity when a 50 kPa (70 psi) vacuum is applied through the oil hole, the switch is operating properly. Check to see that air
doesn't leak. If air leaks, the diaphragm is broken. Replace the switch.
