Check Engine Light Service Toyota Camry

What do you do when you're driving along in your Toyota Camry and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you're like most Toyota owners, your heart sinks a little because you have little idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn't mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your Toyota Camry checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your Toyota Camry's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can't correct, a computer turns on your check engine light. This amber or yellow light is typically labeled "check engine" or "service engine soon", or the light may be nothing more than a picture of an engine, or a picture of the engine with the word "check."

When the light turns on, the ECM stores an engine code or "trouble code" in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Toyota auto repair mechanics. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it.

Toyota Camry Check Engine Light Codes

The check engine light turning on can be quite intimidating to see that little light on your vehicle's dashboard suddenly illuminates, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your Camry. There are hundreds of different codes that your check engine light can represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. Unfortunately, obvious and helpful vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of possible OBD codes, there are also hundreds of possible reasons for the light, including:

Loose Gas Cap or Missing Gas Cap
Transmission issues
O2 Sensor
Old Battery
Emissions controls issues
Fuel and air metering systems problems
Computer output circuit issues
Bad Spark Plugs
Ignition system faults

This is why it is important for someone who does not have a lot of automotive knowledge to not assume what a code means.

When your check engine light comes on, you should get it checked out quickly by a certified Toyota mechanic.

What could cause the check engine light to come on in a Toyota Camry?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle's engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your Toyota Camry, we highly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

Issues with all aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your Toyota Camry if it's not installed properly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the automobile from starting. If these issues sound familiar, bring your Camry to Toyota and have our unit of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing all issue. Getting accessories, incredibly aftermarket parts and accessories, or using OEM parts first place might rate a tiny bit more but could save you money from having to get low work and wear and tear caused by low installation work corrected.
Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, admitted as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your automobile will be less capable when it comes to fuel economy.
Your catalytic converter is bad or going bad. The catalytic converter is a part of your Toyota Camry's exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Nalley Toyota of Roswell offers a complimentary multi-point inspection with every Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your Toyota Camry will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause alternative problems from overheating.
Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Camry is what determines how much fuel is parmount to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to authentic changes, identical altitude. If your Toyota Camry is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
New Spark Plugs or Plug Wires are parmount for your Toyota Camry. The spark plugs are the part of your engine that ignites the air/fuel variation in the combustion chamber of your automobile. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If you're spark plugs or spark plug wires are bad or popular, you will experience low performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or wear and tear to ignition coils and O2 sensors, fundamental to more expensive repairs.
Your Toyota Camry has a vacuum leak. Every Toyota Camry has a vacuum system that performs a wide variation of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, incredibly if they're exposed to forceful heat or extreme cold.
One of the most acceptable and countless cause is that your Toyota Camry gas cap is loose, damaged or missing. The gas cap for your Toyota Camry serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is popular or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on expeditiously after you put gas in your Toyota Camry, first thing you should check is to make satisfied the cap isn't loose — or that it's still on your car's roof or at the fuel pump.
The battery is low or dead. The battery in you Toyota Camry every harsh. Without a car battery, your car won't start, light up the road ahead, play the radio or charge your phone. Today's car batteries last much longer than they did a few decades ago, and they don't really require maintenance. The estimate of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
