Re: check engine light is staying on
55 No Malfunctions -I have a dodge shadow that puts this code out just to let you know that the computer is working correctly. It is more of a self test code. If you didn't get this code, then there was something wrong with the self diagnostics.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Mechanic (only for users in the US for now) and get all the help you need. Goodluck!

The battery light is a "check engine" light. This means that one or more of your oxygen sensors failed. If you take your vehicle in to Parts Source, you can get a free diagnostic reading to get the trouble code. Then ask a mechanic or ask Canadian Tire or the like what the trouble code means. Having this light on means that your sensors are detecting emmissions.
Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.
Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.
The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:
Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46.Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.
When the check engine light is turned on by the systems computer control module it means that a problem has been detected in the engine or transmission. The list of faults is long (over 100) and you must have the system scanned with a special tool to find out what fault code or codes turned on the light, once the code is known then the diagnostics to repair this code must be done and the correct repair made based on the diagnostics performed.
When that light comes on, it means your computer has detected a problem with it's engine management: a sensor or circuit malfunction, or an emissions-related problem that keeps your engine from running at optimal efficiency. It will store a diagnostic code in its memory to be retrieved with a scan tool to direct a mechanic where to start looking for the problem. No way of knowing if it's a major or minor problem without getting the diagnostic codes. If light stays on, have it checked right away.
If the light was flashing when it came on, then it means your engine is misfiring.
A solid light can mean anything from a loose/faulty gas cap to a transmission issue.
light comes on when the computer detects a
fault of some sort in its diagnostic tests. If it keeps detecting this
issue, the light will remain on. If the light turns off, then it has
detected that the issue may no longer be present.
order to find out what the exact reason was for your light, You need to
have your car computer scanned to retrieve the code that
the computer would have stored when the light triggered. Most garages
will do this free of charge. The code will tell you what may have
caused the light to initially turn on.
that code definition is "Evap high purge flow fault". It means you may have a problem with the evaporative system. this system routes fuel fumes back to the fuel tank. If you want to try and clear this code, find the radio code for your car and then disconnect the battery for 30 seconds. Reconnect the battery and the check engine light should be out. You will then need the radio code to reset your car stereo. the check engine light may stay off if the condition was a transient one. If not, the light will come back on after you drive the car two drive cycles. That is: two starts, warm ups and shut downs. If the light returns, have a mechanic check it out.
Hi, the clunking sounds like a constant velocity joint (C V joint). It is usually better to replace the whole shaft (half shaft). Yes there are 2.
The check engine light can be checked at any Autozone or similar store. They will put an ODB2 scanner on it for free. Thier diagnostic machine will give them a code similar to code 34 or something like that. This is where they mess up. They don't know what that means. You may need to get the code and do a little searching yourself to get an acurate meaning. DO NOT BELIEVE THE AUTOZONE EMPLOYEE INTERPRETATION ON THE DIAGNOSTIC. Do the search yourself.
Good luck and let me know how it turns out. James
We had our check engine light come on and stay on. We took it to our mechanic who has a machine that reads codes. You need to find out what the problem is relating to the diagnostic code and then you can find out what kind of repairs you are looking at. Our code turned out to be an O2 sensor that he said would do no harm to the car at all other than slightly affect our gas mileage. If the check engine light comes on and flashes on and off you need to go directly to a mechanic as this is a more serious problem.
