DIAGNOSTICS
The following sensor diagnostics are when the
sensor is properly connected with a 1kohm pull-up
load to Up.
FAULT PIN OUTPUT
Open (Signal of Sensor) > 95%Vcc
Open (Ground of Sensor) > 95%Vcc
Open (Signal and Ground) > 95%Vcc
Short (Signal to Ground) < 5%Vcc
PART CHECK
K25W241A
1) SCANNER
1] (DIAGNOSTIC) - 4] Engine - 1] DPF Logger -
1] Self check - 10] Exhaust gas Temperature.
Voltage - 11] Exhaust gas Temperature.Voltage
2) How to check:
1. Turn off ignition switch
2. Separate EGTS sensor from connector
3. Measure resistance at normal temperature by
multi-meter
4. Check the resistance value as 220 ± 20Ω at
room temperature(25°C)
3) Note: Dif ferent resistance values in dif ferent
temperatures after driving need checking to
the resistance value in reference to original
value.
4) EGTS sensor installation torque: 4.0 ~ 5.0 kgf•m
Don’t separate only sensor from main board
to avoid gas leak out of tail pipe
Check sensor when it is dropped in use.
