how to reset check engine light of your car

-
A common question is "How do I reset or check engine light off?". You have a few options of "reseting the light". Technically what you have to do is clear the trouble codes stored in the car's computer.

Your car's onboard diagnostic system triggers the Check Engine Light when it detects a malfunction vehicle. On 1996-newer vehicles when something is wrong, an OBD-II troubleshoot code is stored and the MIL (malformation indicator lamp) is lit up to inform the driver's problem. The MIL is generally referred to as the Check Engine Light.

NOTE: The Check Engine Light (CEL) or Service Engine Soon (SES) light lights steadily indicate that there is a problem with the vehicle. Please read the first code, and fix the problem before reseting the CEL / SES light (i.e. clear the codes).

The preferred method of the clearing of the car's memory and turning off the light is a scan tool used and the code is clear. It is a simple procedure and will not cause any side effects. AutoZone reads trouble codes for free, they may also clear them for you, just ask. Other local auto parts stores may offer the same service, so call around. If you have an interest in diagnostics you may want to consider your own code reader buying, they may be as little as $ 40 for a simple one.

As well, if the problem is fixed the light should go out on its own after a successful start. The number of starts varies depending on the trouble code and the vehicle make / model.

As an alternative, you can try the car's main battery for about 15-30 minutes for disconnecting, and reconnect it. Please note that this method is not recommended and may result in radio presets being lost and other unknown effects. This method also results in the OBD-II monitor being reset.

Tip: Be sure that the repair is complete or otherwise the check engine light can be reversed right away

how to oxygen sensors work detele

00's oxygen sensors started to give way to more precise air fuel ratio sensors.  Air fuel (A/F) ratio sensor An air fuel ratio (A/F) sensor measures oxygen content of the exhaust in a wider range. Looking similar to a conventional oxygen sensor, the A/F sensor has more wires. It is also known as "broadband lambda sensor" or "lambda probe." The air fuel ratio sensor is installed in the exhaust manifold or in the front exhaust pipe, before the catalytic converter. The job of the air fuel ratio sensor is to measure the oxygen content in the exhaust and provide feedback to the engine computer (PCM). Based on air fuel ratio sensor signal, the computer adjusts the air to fuel ratio to keep it at the optimum level, which is about 14.7:1. Air fuel ratio sensor problems Problems with air fuel ratio sensors are common. Often a sensor gets contaminated or simply fails. In some cars, the heating element inside the sensor fails causing the malfunction. For exa...

A starter is an electric motor that turns over or "cranks" the engine to start it. It consists of a powerful DC (Direct Current) electric motor and the starter solenoid that is attached to the motor (see the picture). In most cars, a starter motor is attached to the transmission, see these photo 1  and  photo 2 .  Starter motor. Click for  larger photo The starter motor is powered by the car battery. To turn over the engine the starter motor requires a very high electric current, which means the battery has to have sufficient power. If the battery is discharged, the lights in a car might come on, but it won't be enough power (current) to turn over the starter motor. What are the symptoms of a bad starter motor: With the fully charged battery, when starting a car, nothing happens or there is a single click, but the starter motor doesn't run, even though there is a 12-Volt power at the starter control terminal. Another symptom is when the starter motor runs, ...

how to crankshaft position sensor is work

Ford Crankshaft position sensor (CKP) The crankshaft position sensor measures the rotation speed (RPMs) and the precise position of the engine crankshaft. Without a crankshaft position sensor the engine wouldn't start.  In some cars, the sensor is installed close to the main pulley (harmonic balancer) like in this Ford in the photo. In other cars, the sensor could be installed at the transmission bell housing, or in the engine cylinder block, as in the photo below. In the technical literature, the crankshaft position sensor is abbreviated to CKP. How the crankshaft position sensor works In this GM engine, the crankshaft position  sensor is installed at the cylinder block The crankshaft position sensor is positioned so that teeth on the reluctor ring attached to the crankshaft pass close to the sensor tip. The reluctor ring has one or more teeth missing to provide the engine computer (PCM) with the reference point to the crankshaft position. As the crankshaft ro...
