WARNING:
-
A hot engine can cause severe burns. Turn off the engine and wait until it is cool before removing the exhaust system.
1. Disconnect the negative battery cable..
2. Remove the aerodynamic under cover No.2..
3. Remove the oil pressure switch..
4. Apply air pressure of approx. 40 kPa {0.41 kgf/cm2, 5.8 psi} to the oil pressure switch as shown in the figure.
5. Measure continuity between oil pressure switch terminal A and the thread area.
-
If there is any malfunction, replace the oil pressure switch.
