FUEL INJECTOR INSPECTION[L3 WITH TC]

Operation Test

1. Carry out the "Fuel Injector Operation Inspection". (See01-03-78 ENGINE CONTROL SYSTEM OPERATION
INSPECTION[L3 WITH TC].)
• If not as specified, perform the further inspection for the fuel injectors.

Resistance Inspection

Note
• Perform the following procedure only when directed.
1. Turn the ignition switch to the LOCK position.
2. Disconnect the negative battery cable.
3. Remove the fuel delivery pipe. (See 01-14-23 FUEL INJECTOR REMOVAL/INSTALLATION[L3 WITH TC].)
4. Disconnect the fuel injector connectors.
5. Measure the resistance of the fuel injector using a
tester.
• If not as specified, replace the fuel injector.
(See01-14-23 FUEL INJECTOR REMOVAL/
INSTALLATION[L3 WITH TC].)
• If as specified but "Operation Test" is failed,
carry out the "Circuit Open/Short Inspection".
Inspect for open or short circuit.
