1)CHECKING THE CIRCUIT DIAGRAM OF ETS(Engine Temperature Sensor)
Fault code number is displayed by MIL
CHECKING CIRCUIT
Coupler terminal is based on the side of wire-harness
Checking Procedure
1) Turn off the ignition key .
2) Check to see if the ETS(Throttle Position Sensor) coupler is loose, or bad.
If there is no defect, measure the input voltage of ETS.
3) Disassemble the coupler of ETS
4) Turn on ignition key.
Measuring terminal :
ECU No. 20 (Gr/L: GREEN/BLUE) ~
ECU No.4 (W/R : WHITE/RED)
Measure the terminal voltage of ETS’s coupler.
Measuring voltage : 4.5[V] ~ 5.5[V]
Remarks : Measuring unit for voltage : voltage [V]
If the voltage value is not normal,
Check to see if the ECU coupler is loose, or bad contact.
Check the ‘G/L’’ electric wire, ‘W/R’ electric wire, ‘W/R’ electric wire to see if they have been
broken or have short- circuited.
5) If the voltage value is normal, turn off the ignition key.
6) Disassemble the coupler of ETS, and measure the resistance of ETS.
Resistance of ETS :1.6[k
]~10.6[k
],20
~80
Measuring terminal : Each terminal of ETS
Remarks : Measuring unit for resistance : Resistance ‘ R ‘ [k
]
