Checking Procedure
6) Check continuty between the Sensor Ground Terminal of TPS and Earth.
The continuty TPS : 0[
],20±1
Measuring Terminal : ECU No. 4 (W/R : WHITE/RED) ~ EARTH
Remarks : Measuring unit for resistance : Resistance ‘ R ‘ [
]
7) If not problem, measure the resistance of TPS.
By turning round throttle Lever, measure the resistance.
The resistance of TPS
If the throttle is totally closed : 1.38~1.6[k
],20±1
If the throttle is totally opened : About 2.4[k
],20±1
Measuring Terminal :
ECU No. 19 (Gr/L: GRAY/BLUE) ~
ECU No.4 (W/R : WHITE/RED)
Remarks : Measuring value of resistance : Resistance[k
]
8) If resistance and the continuty are not abnormal.
Adjust correctly the position of TPS
Replace the TPS with the new one and re-check.
9) If resistance and continuty are normal, connect the coupler of TPS.
10) Turn on the ignition key.
11) Measure the TPS voltage of the wire-harness to check the ECU.
Rotate the throttle lever, measure the voltage
Measuring terminal:
ECU No. 19 (Gr/L: GRAY/BLUE) ~
ECU No.4 (W/R : WHITE/RED)
Output voltage of TPS
-If the throttle is totally closed : 0.1~0.6[V]
-If the throttle is totally opened : 4.0~5.5 [V]
Remarks : Measuring unit for voltage : Voltage [V]
12) If the measured voltage is abnormal,
Replace the TPS with the new one, and re-check.
If the measured voltage is normal,
Check the ‘GR/B’ electric wire, ‘GR/L’ electric wire, ‘W/R’ electric wire to see if they have been broken or
have short- circuited if there is a bad contact of terminal No. 4, No. 18, No. 19 of ECU coupler.
If there is no problem in wires, ECU has broken down.
Replace ECU with the new one, and recheck.
13) After fault repaired, To erase the memorized fault code in the ECU is refer to how to remove the fault code(5-10).
