Check Engine light-weight (which is formally known as “Malfunction Indicator Lamp” or MIL) — is meant to alert the driving force once one thing has gone wrong with the vehicle’s operations.

Depending on however the system is designed and also the nature of the matter, the Malfunction Indicator lamp/light might return on and blast off, stay on unendingly or flash — all of which may be terribly confusing as a result of you have got no manner of knowing what the sunshine suggests that.

Here’s how it works:

When the OBD II system detects a fault, it sets a “pending code” in cars laptop.

The MIL light-weight does not return a result of the system has to make certain the matter is real and not a brief flaw.

If constant downside happens on a second trip (under constant driving conditions) — the OBD2 system can set a diagnostic hassle code (DTC) and switch on the Malfunction Indicator (MIL) lamp.

Ok, Now What?

If the Check Engine light-weight comes on — will it indicate a significant downside or not?

The only thanks to apprehending is to attach a code reader or scan tool to the OBD-II diagnostic connective or your automobile (all vehicles have one by law) — and browse out the code.

It’s also vital to notice if the other warning lights square measure on, or if the engine is creating uncommon noises, running poorly, steaming, smoking or otherwise showing obvious signs of hassle.

If the OIL WARNING LAMP is on, shut the engine off at once. Running the engine low on oil will cause serious harm to the bearings, rings and valvetrain.

If the TEMPERATURE WARNING LAMP is on, shut the engine off at once. The engine is warming probably thanks to a fluid leak, low fluid level, unhealthy thermostat, failing fan motor or fan clutch, broken belt or radiator obstruction.


How We Fix

Our team will go beyond and use advanced code readers and scan tools to diagnose the issue. Most dealership will charge a large sum of money for this and often not always find the cause of the problem. Other problems can still remain and the code alone will not tell you which ones half has, failing and desires to get replaced.

Our Experts go further

A hassle code is barely a cause. it is not the ultimate designation. Somebody still has got to scrutinise the assorted elements within the affected circuit or system to work out what precisely is inflicting the matter. This typically needs following a drawn-out diagnostic chart to isolate the fault. Most competitors will simply jump to conclusions typically ending up in a faulty designation which can be costly.

Other companies can also miss harder to diagnose square measure misfire codes.

Our software will find misfires in individual cylinders additionally as random misfires.

If it generates a misfire code for one cylinder, it solely tells you the cylinder is misfiring.

The underlying cause can be a nasty electrical device, a nasty plug wire, a weak coil on a distributionless ignition (DIS) or coil-on-plug (COP) system, an unclean or dead fuel contrivance, or a compression downside (bad valve, leaky gasket, rounded cam lobe, etc.).

As you’ll be able to see, there are multiple possibilities so it takes our highly trained diagnostic expertise to isolate the fault before any parts can be replaced.
