#engine check light

Yes, modifying an aftermarket car header can cause an engine O2 sensor check light. This is because aftermarket headers are often designed to improve airflow and performance, but they can also change the exhaust gas flow. This can cause the O2 sensors to read inaccurate readings, triggering the check engine light. Why do some vehicles not have this error light issue? Some vehicles do not have…

There are numerous reasons the check engine light could come on. Diagnostic tools will inform the system responsible, and you can perform tests to find the exact issue. These are some common problems which can trigger a check.

A battery problem can result in the check engine light to flash.

Check the condition of the battery using a voltmeter. it must at a minimum, meet the minimum cranking amp, as stated in your owner's manual. The battery may deplete over time, or it could be left on for a few hours. Also, inspect the fuse box for any damage or corrosion.

Check engine light could be caused by a fan, alternator, or serpentine belt issues

The belts of the engine are essential components of the engine and perform a great job keeping the car cool. They are susceptible to wear and tear as time passes or could be damaged by loose debris. To improve your engine's performance it is important to check the condition of the belts.

An oxygen sensor issue can trigger a check engine light

The oxygen sensor monitors the inert oxygen in the exhaust. This also monitors how much fuel is burned and is directly related to emissions. The sensors are frequently covered by exhaust fumes, which can affect the quality of the sensor. A faulty sensor will mean that the ECU alters itself to reduce the effectiveness of the engine, resulting in an increase in MPG. This can eventually cause catalytic converter problems that can result in higher prices that PS2000. The DTC will tell you the oxygen sensor that is damaged and can easily be replaced.

A leaky fuel cap can cause a check engine warning light to flash.

Cracked broken, loose, or cracked fuel caps may cause contaminants to get into the system, and the fuel vapours to leak out. Both of these can affect the engine light as they can both cause significant emissions. To fix it the best way to fix it, get it fixed or replaced if damaged. It shouldn't cost a lot and all you need is a screwdriver. This should also help your MPG.

Check engine light could be caused by a defective catalytic convert

The catalytic converter is part of the exhaust system which reduces the amount of harmful exhaust gases. It converts carbon monoxide, which is deadly, into carbon dioxide. A damaged catalytic converter can decrease your fuel efficiency and may put the car in limp mode. The catalytic converter usually fails in driving conditions that are urban, with many stop-starts. This prevents the catalyst from being able to regenerate. You can fix the catalytic converter using the time to take a uninterrupted drive on a motorway, which will trigger systems that clean soot from the catalytic converter. If the problem persists, you'll need to call the mechanic to request a regeneration.

Check engine lights can be the result of a malfunctioning mass flow sensor.

The ECU is alerted by the mass air flow sensor of the quantity of air that is flowing into the engine. This permits the ECU to alter the consumption of fuel. A malfunctioning mass airflow sensor can cause your car to stop and cause an enormous impact on MPG. A malfunctioning air filter can result in it failing. This needs to be replaced once a annually during your scheduled or annual service. A malfunctioning mass airflow sensor can be controlled, but it will cause an expense to your wallet.

Faulty spark plugs can cause a check engine light

Spark plugs are the source of spark that ignites every explosion in your engine. If your car is speeding up "hiccups" could indicate an issue with the plug. Plugs are replaced during our main service once they fail after approximately 3000 miles.
