Checking oil pressure [Toyota RAV4 XA10]

Low oil pressure may indicate the need for engine repair. The oil pressure warning light serves to signal that the oil pressure is dangerously low. Even the pressure gauge on the instrument cluster only shows relative pressure. Oil pressure must be checked by a certified mechanic (not electric) pressure gauge.

The oil pressure sensor is installed at the end of the cylinder head on the side opposite the timing drive. Unscrew the sensor and screw in the pressure gauge hose tip in its place.

Connect the tachometer to the engine in accordance with the operating instructions supplied with it.

Start the engine and warm it up to operating temperature. Check the oil pressure at idle and at 3000 rpm. If the pressure is lower than specified, the crankshaft bearing clearance may be increased or the oil pump may be faulty.
