E TEST ONTARIO CHECK ENGINE LIGHT DRIVER
The check engine light is geared towards alerting the driver when the computer sees a problem with the vehicles emissions system and there are Thousands of possible reasons for the light to come on. How is this design flaw? It is mandated by law by the Department of ecology. Please remember I am unbiased and only trying to factually educate you and other readers.Ī check engine light can come on because the driver puts gas in the car and did not tighten the gas cap up. Of Ecology Authorized Emissions Specialist More importantly we can provide you with tips to help reduce the amount of emissions your vehicle emits and keep you an informed Subaru owner.ĪSE Master Certified Technician, L1 Advanced Engine Performance Certified We will accurately diagnose the failure, any potential causes of the failure and keep you informed the whole way through.

Specializing in Subaru repair gives us an advantage over other general repair shops when it comes to the diagnoses and repair of the check engine light and vehicle emissions systems on your Subaru. Until the monitoring system is back to ready status the ECM doesn’t know about a device or a condition.
E TEST ONTARIO CHECK ENGINE LIGHT CODE
This is why sometimes a code can be cleared and not come back for weeks. It takes a specific drive cycle to return the monitoring systems back to ready status and the whole time the monitors are off they are not monitoring the emissions control devices. When a code is cleared, the emissions systems monitors are also turned to not ready status.

It is simply not enough to have the code number but rather a thorough analysis must be performed by a qualified professional technician. It is almost impossible to accurately diagnose and repair a conditional code with a code reader from a local parts house. Conditional codes are the hardest to accurately diagnose and repair and are typically the ones that do the environment the most harm.

A component code usually indicates a problem with a particular device, its circuitry or controls. There are essentially two types of OBD II Fault codes, conditional and component. These are just two examples of many possibilities. The catalyst system is designed to lower tail pipe emissions to acceptable levels. The gas cap is meant to keep the fuel vapors sealed in the tank and evaporative emissions system rather then allowing the fuel vapors to enter the atmosphere as hydrocarbon emissions. Normally neither one will adversely affect the vehicles performance but both will allow the vehicle to excessively pollute our environment. But the light can also come on when the catalyst system has failed. In some cases the light can come on when the gas cap is loose. But what the light represents is a potential failure in one or more of the vehicles systems that are meant to control the level of tail pipe and evaporative emissions produced to acceptable levels. In many cases the vehicles overall performance won’t change much if at all when the light comes on, and is thus not taken seriously by the majority of car owners. The check engine light comes on when the ECM (Engine Control Module) recognizes a malfunction with an emissions control device or an emissions control device monitoring system or if a specific condition is not being met.

Part of this technology involves the check engine light or MIL. As well as meet newer vehicle emissions regulations. had to be OBD II compliant (On Board Diagnostics two).
