You get into your car, turn the key and instead of the engine roaring to life, there’s just silence. That sinking feeling often points to a battery issue. Whether the headlights were left on or the battery is just old, deciding whether to jump-start or replace can save you a lot of hassle. Here is […]

While still in school, you may be asked to use your multimeter for many testing and diagnostic tasks as an aspiring electrician or engineer. A multimeter does more than measure voltage and resistance. Use it to diagnose electrical issues, including checking whether a fuse is intact. This guide walks through how to assess a fuse’s […]

The gasoline vapors are sucked out of the canister and burnt within the engine when the engine is running at a specified temperature and speed. How much fuel vapor is released from the charcoal canister is carefully regulated by the purge valve. As a component of the vehicle’s Evaporative Emission Control (EVAP), the purge valve […]

Keep a multimeter in your automotive toolkit. It measures voltage, current and resistance. Use it for testing the purge valve’s terminals for consistent resistance, a procedure that’s uniform across different vehicle makes and models. This helps your car’s emission system work efficiently for both performance and the environment. Resistance and current flow can be impeded […]

On many cable-operated throttle bodies, idle speed is set by an idle air control device. Technicians also call that part an IAC valve or ISC valve. Air metered through a bypass around the throttle plate is what changes the idle. The idle speed can be raised by increasing the airflow through the bypass circuit around […]
