Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Injector Resistance Check
Disconnect fuel injector connector. Using an ohmmeter, measure fuel injector resistance across both terminals. On 1.8L and 2.0L non-turbo, resistance should be 13-16 ohms at 68°F (20°C). On 2.0L turbo, resistance should be 2-3 ohms at 68°F (20°C). If resistance is not to specification, replace fuel injector.
