CHECKING OF INTAKE TEMPERATURE SENSOR
1) If voltage value is normal, turn off ignition key.
2) Disassemble the MAPAT coupler and measure the resistance of intake temperature sensor.
Resistance of intake pressure sensor : 2000±100[
Ω
], 25±1
Measuring terminal :
ECU No. 28(P/B :PINK/BLUE) ~
ECU No. 3(P/G : PINK/GROUND)
Remarks : Measuring value for resistance : Resistance[
]
The Voltage of air pressure;
24 ~ 26[
] : 1800~2200[
]
99 ~ 101[
] : 161~206[
]
3) If measuring resistance is not normal,
Replace the MAPAT sensor with new one and it rechecks.
If the measured voltage is normal,
Check the ‘P’ electric wire, ‘P/G’ electric wire, ‘P/L’ electric wire
to see if they have been broken or have short- circuited
if there is a bad contact of terminal No. 3, No. 26, No. 27
of ECU coupler.
If the electric wire is no problem, ECU is broken.
Replace the ECU with the new one, it rechecks.
4) Turn on the ignition key. Start the engine and idling.
5) Measure the voltage of intake pressure sensor for ECU check.
Measuring the voltage of intake pressure sensor
- Measuring terminal:
ECU No.28(TBA)
~
ECU No.3(IMP ground)
- Measuring voltage: 0.1[V] ~ 4.9[V]
Remarks : Measuring unit of voltage : Voltage [V]
6) If the measured voltage is not normal,
Check the ‘P’ electric wire, ‘P/G’ electric wire, ‘P /L’
electric wire to see if they have been broken
or have short- circuited.
Replace the MAPAT sensor with new one and it rechecks.
If the measured voltage is normal,
Check the ‘P’ electric wire, ‘P/G’ electric wire, ‘P/L’ electric wire
to see if they have been broken or have
short- circuited if there is a bad contact of terminal
No. 3, No. 26, No.28 of ECU coupler.
If the electric wire is no problem, ECU is broken.
Replace ECU with the new one, it rechecks.
7) After fault repaired, To erase the memorized fault code in
the ECU is refer to how to remove the fault code(5-11).
