Component Inspection

WARNING: This page is about a different car, the 2018 Nissan NV3500 HD, 2018 Nissan NV2500 HD, and 2018 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

COMPONENT FUNCTION CHECK

Turn ignition switch ON.

Check the voltage between ECM harness connector terminals as follows.

ECM
Connector	+	-
	Terminal
E16	107	112

NOTE: Since this sensor is an atmospheric pressure sensor, values vary with atmospheric pressure and altitude.

Measure the atmospheric pressure.

NOTE: As the atmospheric pressure described on the synoptic chart is the value at sea level, compensate the pressure with the following chart.

Altitude (m)	Compensated pressure (hPa)
0	0
200	-24
400	-47
600	-70
800	-92
1, 000	-114
1, 500	-168
2, 000	-218

Check that the voltage is within a specified range as in the following chart.

Atmospheric pressure (hPa)	Voltage (V)
800	3.1 - 3.7
850	3.3 - 3.9
900	3.5 - 4.1
950	3.8 - 4.3
1, 000	4.0 - 4.6
1, 050	4.2 - 4.8
