Static Test
- Ignition/Vehicle - Off
- Disconnect the appropriate electrical connector: Q17 Fuel Injector
- Test for 11 to 14 ohms between the test points: Control terminal 2/B & Ignition circuit terminal 1/A
- If not between 11 and 14 ohms
Replace the appropriate component: Q17 Fuel Injector
- Go to next step: If between 11 and 14 ohms
- If not between 11 and 14 ohms
- Test for infinite resistance between the test points: Each terminal of the component & The component's housing
- If less than infinite resistance
Replace the appropriate component: Q17 Fuel Injector
- Go to next step: If infinite resistance
- If less than infinite resistance
- All OK.
