What Could Be Uncovered During An Engine Diagnostics Test

The engine is the powerhouse of the car, where any issues with this component can cause your vehicle to break down completely. In simple terms, the main purpose of the engine is to convert fuel into energy, allowing the vehicle to move.

When this function is compromised, you should be able to tell by changes to your driving experience. Alternatively, the check engine light on your dashboard will let you know that it’s time to investigate.

An engine diagnostics test can be carried out by a professional mechanic, either at a garage or on the roadside. This will allow you to uncover the problem with the engine, so steps can be taken to repair the vehicle.

Read on for a look at some of the issues that could be uncovered during engine diagnostics.



Emissions System Failings

Engines typically contain an emissions system, which works to limit the release of harmful gases from fuel combustion. If there’s a problem with the catalytic converter or your exhaust system, then this will be flagged during diagnostics, where you may also uncover these issues if you fail an emissions test.

Ignition Trouble

A successful driving experience depends on having a fully functioning ignition system, where malfunctions in this area will be detected during engine diagnostics. This could mean that there’s an issue with the vehicle’s ignition coils, the spark plugs or the timing of the ignition, all of which can lead to noticeably poor engine performance.

Fuel System Issues

Because car engines are constantly working to convert fuel into energy, this can lead to a range of fuel-related issues. Engine diagnostics may reveal a clogged fuel injector or incorrect fuel pressure, where this will have an impact on general engine efficiency.

Battery Problems

An engine diagnostics test may also detect issues with your car’s battery or your charging system if you’re driving a hybrid vehicle. Various faults with the alternator for instance could cause an electrical failure, preventing you from starting your vehicle.
