DIAGNOSTICS
The following sensor diagnostics are when the
sensor is properly connected with a 5kohm pull-up
load to Vcc.
FAULT PIN OUTPUT
Open 1 > 96%Vcc
Open 2 > 96%Vcc
Open 3 > 96%Vcc
Short 1-2 < 4%Vcc
Short 1-3 > 96%Vcc
Short 2-3 < 4%Vcc

1] Self check - 8] Differential pressure voltage -
9] Differential pressure
2) Check the voltage 0.5± 0.2V under atmosphere
(Voltage of atmospheric pressure = 5V*10%)
3) How to check:
1. Turn off ignition switch.
2. Separate pressure sensor from connector.
3. Separate hose from pressure sensor.
4. Loosen bolts and separate pressure sensor
from car
4) DPS sensor installation torque: 1.0 ~ 1.2 kgf•m
4.4.2 EGTS SENSOR (EXHAUST GAS
