Fuel Injector Resistance Test

Resistance Inspection

NOTE: Perform the following test only when directed.

1. Disconnect the fuel injector connectors.




2. Measure the resistance of the fuel injector using an ohmmeter.
- If as specified but On-vehicle Inspection is failed, carry out the "Circuit Open/Short Inspection".
- If not as specified, replace the fuel injector.

Resistance
12 - 16 Ohms [20 °C {68 °F}]
