Harness Connector
Inspection
- Switch "OFF" the ignition and disconnect the negative (-) batteiy terminal.
- Disconnect the fuel pressure regulator valve connector.
- Measure resistance between the fuel pressure regulator valve terminals 1 and 2.
- Check that the resistance is within the specification.
Specification : 0.53 - 0.58 20ºC (68ºF)
