CHECKING METHODS BY FAULT CODES
Checking of the Injector circuit
The fault code is displayed by MIL
Checking Circuit
Coupler terminal is based on wire harness.
Checking Procedure
1) Turn off the ignition key.
2) Check to see if the injector coupler has come loose or the wire is peeling off.
If there is no problem, measured the resistance of injector.
3)Disassemble the injector coupler and measure the resistance between injector terminals.
The resistance of injector : 14.5±0.7[
], 20
Remarks : measuring unit for resistance : resistance ‘ R ‘ [
]
4)If there is no problem, check the continuity between each terminal and ground.
The resistance between each terminal and ground :
∞
[
]
If resistance value is not normal, replace injector with the new one.
5)If the resistance is normal, turns on the ignition key
- If the fuel pump operated for 3 seconds, the power supply relay of injector is normal.
6) Measure between the voltage of coupler.
Measuring terminal :
BLACK/RED electric wire ~
ground
Measuring voltage : battery voltage – 1.0[V]over
Remarks : Measuring unit of voltage : voltage [V]
