The fuel pick up system is part of the fuel pump
module mounted inside the fuel reservoir.
The fuel level gauge sender is also mounted on
this module.

Injection Oil Low-Level Sensor
The sensor sends the signal to the low-oil level
light in the fuel gauge or the LED in the Information
Center.
TYPICAL
1. Injection oil low-level sensor
The bottom of the sensor has a small reservoir
with two small holes underneath to let the oil en-
ter inside and one at the top to let the air enter
allowing the oil to flow out.
When there is enough oil inside the oil tank (and
therefore in the sensor reservoir), the sensor de-
tects the liquid and the light DOES NOT turn on.
When the oil level goes at critical LOW level inside
the oil tank (and therefore in sensor reservoir), the
sensor detects the absence of liquid and the light
TURNS ON.
To check the oil sensor, unplug its connector and
pull sensor out of oil tank.
Using a multimeter, check the continuity between
the BLUE and BLUE/BLACK terminals.
When sensor is out of oil tank and its reservoir is
empty, resistance must be infinite (open circuit).
NOTE:
Wait about 15-20 seconds before taking
any reading to give the oil enough time to flow out
or inside sensor reservoir.
Soak sensor in oil so that its reservoir fills up. Max-
imum resistance should be approximately 2
Ω
(closed circuit).
