Test Description

WARNING: This page is about a different car, the 2002 Isuzu Trooper, 2002 Isuzu Rodeo Sport, 2002 Isuzu Rodeo, 2002 Isuzu Axiom, and 2002 Honda Passport. However, it is still accessible from the selected car via links, so may be relevant.

2

Relieve fuel pressure by connecting Fuel Pressure Gauge (J34730-1) or equivalent to fuel pressure connection on fuel rail. Place fuel pressure gauge bleed hose in an approved gasoline container. With ignition off, open valve on fuel pressure gauge.

3

Record lowest voltage displayed by DVOM after first second of test. (During first second, voltage displayed by DVOM may be inaccurate due to initial current surge).

Voltage displayed by DVOM should be within specified range.
Voltage displayed by DVOM may increase throughout test as fuel injector windings warm and resistance of fuel injector windings changes.
An erratic voltage reading (large fluctuations in voltage that do not stabilize) indicates an intermittent connection within fuel injector.
