Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: DESCRIPTION (2008 Sequoia)

Oil Pressure Gauge Malfunction

DESCRIPTION

The oil pressure sender detects the oil pressure generated when the engine is started. The combination meter determines that the engine is running when the engine speed is 400 rpm or more, and determines that the engine is cranking when the engine speed is 200 rpm or less. The oil pressure receiver gauge detects and indicates the oil pressure applied to the oil pressure sender.

OK

3.

INSPECT OIL PRESSURE GAUGE ASSEMBLY (OIL PRESSURE SENDER GAUGE)

(a) Disconnect the D57 or E13 gauge connector.



(b) Apply battery positive (+) voltage to the sender gauge terminal through a test LED.

(c) Check that the LED does not illuminate when the engine is stopped.

(d) Check that the LED flashes when the engine is running. The number of flashes varies with engine speed.

OK:

LED flashes when engine is running.

LED does not illuminate when engine is stopped.
