CHECK

Conditions (unless otherwise specified)

Readings taken on loose component.

Oil pressure sensor

Connect 5 V direct current between the sensor's terminal pin #2 and #4. Take readings between #3 and #4. The value must be 0.25 - 0.50 V.

Oil temperature sensor

Measure the resistance between sensor's terminal pin #1 and #4, The value should be

R = approximately 7.0 kohms at +15 °C.

R = approximately 5.7 kohms at +20 °C.

R = approximately 4.7 kohms at +25 °C.

R = approximately 3.9 kohms at +30 °C.

R = approximately 3.2 kohms at +35 °C.

Scheme 5

Scheme 5: ELECTRIC FEED PUMP

Type

The electrical feed pump consists of a PWM controlled electrical motor and a gear pump.

characteristic

The resistance between terminal #1 and #2 should be approximately 3 - 5 ohms at +20 °C.

Other information

None.

Scheme 6: TERMINAL

Terminal connector	Control module terminal	Signal type	Other
#1	#C2:1	Control signal, electrical feed pump.	PWM-signal, 5 V
#2	#C2:2	Ground

Check 1

Measure the resistance between feed pump's terminal pin #1 and #2. The value should be approximately 3 - 5 ohms at +20 °C.

Check 2

Measure the resistance between the feed pump casing and terminal pin #1. The value should be much greater or infinite.

Check 3

Measure the resistance between the feed pump casing and terminal pin #2. The value should be much greater or infinite.
