Some of the auto parts retailers around the country will let you borrow a code scanner in the hopes that you will buy necessary parts from them. You can't really test/reset the OBD system without the code scanner. The " check engine light" is by far one of the most misunderstood technological advances It is a warning light that is illuminated when there is a problem affecting the EMISSIONS of the vehicle.. Don't let it bother you as it is a good thing once you understand it. One point that was brought up a recent meeting of technicians was that the amount of hydrocarbons is greater when the gas cap is left off than when the engine is running. Hydrocarbons are part of pollution emitted as gasoline evaporates. Going a step farther, one facet of the emission system is the "Evaporative" portion. This is when the fumes from the gasoline are leaking from the system into the outside air. This is one part of the emission system that can trigger a check engine light. I would say a small percentage of the vehicles that have a check engine light are the result of a loose or inadequate gas cap. But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have multiple computers aside from the powertain computer) will run a series of self-tests. They will only run under certain criteria. And they are different from manufacturer to manufacturer. Some self-tests or
It means you need to go to Autozone or Shucks/Kraagen and have them read the codes with the diagnostic code reader which they will usually do free of charge. Something in or on the engine is malfunctioning and needs repair/replacement. The diagnostic code will tell you where to look for the problem. Oxygen sensor is an example of typical problem discovered but all engine sensors are monitored.
Take it to autozone they will do a free diagnostic test and tell you what is wrong with it....
have an engine diagnostic check at an auto shop to find out what the problem may be.
When the light comes on it's telling you to read the engine diagnostic codes.
The OBD-1 diagnostic connector is located on the back of the block beside the starter. A series of jumper wire locations are used in conjunction with watching the CHECK ENGINE light.
I was told by a mechanic that whenever the engine light is on, it's because of an emission problem. To find out what kind of problem, you need to have it checked by a diagnostic machine at an auto shop.
It is on because the computer has detected a problem with the emissions system. Take it to a trusted mechanic for a scan and diagnostic of the problem.
That is a check engine light. It could be many things but it needs to be hooked to a diagnostic machine to determine what the problem is.
I can, and so can anyone else who has a relatively new engine diagnostic code scanner. However, if the problem is not resolved, the light will return as soon as you start the engine
Check the engine. ===================================================== There is a problem with something that effects the emissions of the engine You need to have the vehicle scanned for any trouble codes to help diagnose and then repair the problem
Take to a qualified mechanic for a diagnostic
Turn the ignition on/off 5 times i.e. on-off-on-off-on within 5 seconds then count the number of times the check engine light flashes. You'll find the associated engine problem at this site: http://www.dirtroad.com/codes.htm Good luck!
There are two diagnostic connection ports, there is a diagnostic connection port below the dashboard on the drivers side. A second diagnostic port can be found in the engine compartment on the firewall.
To answer specifically what is wrong with your vehicle will be impossible without more information. The check engine light comes on when the PCM(computer) sees a problem somewhere in the engine or transmission control system. A sensor may have failed, a solenoid or actuator may have failed, a wiring problem may have developed, or there could even be a problem with the PCM itself. You will have to have a diagnostic run on the vehicle.
have vehicle scanned to determine problem
take it to a dealer or a qualified mechanic for a diagnostic
You must scan the computer to find out the code first Go to a qualified mechanic for a diagnostic
Check engine light usually indicates a problem in the emission control system - have vehicle scanned to determine the problem
An OBD2 car diagnostic reader is used to diagnose any problems that a car might have and it saves time and money. For example, if there is an engine check light on, the OBD2 car diagnostic reader can tell what is the problem so it can be fixed as soon as possible.
Hi, I have that same problem right now, but I took it in for a diagnostic and they told me i needed a new EGR valve, maybe that could be your problem too!
can the fuel injectors on a 1994 grand marquis be checked without removing them from the engine, if so what type of instrument do i use
Have vehicle scanned to determine the problem
The diagnostic code 410, on your 2004 Chevrolet trailblazer, is a reference to a vacuum hose problem. Check the vacuum hoses to make sure they are all connected.
