L300 V6-3.0L VIN R (2001)
Oil Pressure Sender: Description and Operation
The Engine Oil Pressure (EOP) switch is located towards the bottom of the engine block near cylinder # 6. The EOP switch is a normally closed switch
that opens when engine oil pressure exceeds 3.6 ± (2.2) psi. The ECM supplies ignition voltage through a resistor to the EOP switch. With ignition On,
engine Off, the ECM EOP switch input will be low (near 0 volts, switch closed). When the engine is started, end engine oil pressure exceeds 3.6 ± (2.2)
psi, the switch opens and the ECM EOP switch input goes high (ignition voltage).
