Is your check engine light on?

Don’t just ignore the warning! It might be time to schedule a engine diagnostic with West End Auto.

Engine diagnostics help keep your engine running efficiently. The On-Board Diagnostics System, or OBD system, is capable of detecting malfunctions before they lower engine performance or cause severe damage. Because OBD systems are mandatory, your automobile is capable of monitoring and diagnosing its own performance. Engine diagnostics will help detect problems early so minor problems never become major problems. Engine diagnostics also help keep emissions low, and if your engine is malfunctioning, your vehicle might not pass an emissions test.

Most cars today are controlled by computers. The fuel injectors, spark plugs, steering system and more are all told when to fire and when to move by an on-board computer system. West End Auto provides different levels of diagnostic services using the most up-to-date state of the art diagnostic equipment.

If something is going wrong with your car or engine, your on-board computer will tell you what is going on. If the computer senses something wrong with one of your car’s systems, it will turn on a dashboard light, like “ABS Brake” or something less specific like “Check Engine.”

Engine Diagnostics Basics

The OBD System, or On-Board Diagnostics System, was originally installed to monitor vehicle emissions, but it also detects problems within the engine. Both OBD I and OBD II systems exist,
with OBD II systems becoming the standard in vehicles manufactured after 1996.

The OBD is connected to the engine control unit (ECU), which helps your engine run efficiently while keeping emissions low. The OBD can identify and warn the driver of engine malfunction by sending error notifications to the ECU system. The ECU is in charge of several engine processes, including the mixture of air and fuel, emissions, and engine timing. The ECU uses sensors to monitor them or make adjustments. If the ECU detects a malfunction, it triggers the “check engine” light on the dashboard. The OBD system then records the code pertaining to the problem. The code can be accessed by a trained technician through engine diagnostic equipment in order to properly diagnose the issue.
