Protege L4-2.0L DOHC (2003)
Fuel Injector: Component Tests and General Diagnostics
Simulation Test
1. Carry out the "Fuel injector Operation Inspection".
-
If not as specified, perform the further inspection for the fuel injectors.
Resistance Inspection
NOTE: Perform the following test only when directed.
1. Turn the ignition switch off.
2. Disconnect the battery negative cable.
3. Disconnect the fuel injector connectors.
4. Measure the resistance of the fuel injector using an ohmmeter.
-
If not as specified, replace the fuel injector.
-
If as specified but "Simulation Test" is failed, carry out the "Circuit Open/Short Inspection".
Resistance [20 °C {68 °F}]
ZM: Approx.13.8 Ohms
FS: 14.2 - 14.8 Ohms
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.
