How do you check the codes on a Dodge Durango?
To check the code on the 2004 Dodge Durango you can also KEY from the on to start position 4 times (eg. Off to start, off to start, off to start, off) and the code should show up in the odometer reading. For example I just had the MIL come on and I did the KEY thing and found the code was P 0456. If you don't see something try turn the key again three times and then on the fourth turn leave it in the start position. It should show up. the durango need to be pluged into a type of computer that can communicate with the powertrain control module (pcm) if you have an engine malfunction light on. the drb will give you a code, the code will give you an area of the vehicle to inspect ie p0456 (large evaporitive emidssion leak detected) then you will have to inspect that system to find the cause of the code

Why does Toyota Celica engine warning light come on emissions?
The engine warning light for emissions might come on in a Toyota Celica if the Oxygen Sensors are bad. It might also come on if the catalytic converter is not working properly or is plugged.
What does it mean when the engine warning light comes on for a 2002 Dodge Dakota?
You would have to connect a diagnostic tool to it to find out exactly, but, in general, the yellow check engine light indicates a problem with the emissions control system. Usually this doesn't significantly affect how the vehicle runs, and isn't a critical problem, but it does mean that the engine either may be using more fuel or may be polluting more, or both. And, if you live somewhere that requires vehicle emissions testing, your vehicle will fail automatically if the check engine light is on.
This may or may not be your problem, but (perhaps) the most common cause for the check engine light to come on in Dakotas of this age is cracked vacuum lines, particularly at a valve located near the battery, and/or near the fuel vapour canister under the cab inside the driver's side frame rail. Sometimes you can just trim the line a little shorter to eliminate the crack, but sometimes you'll need to replace the whole line. Either way, it's a really cheap fix if you do it yourself.
Also worthy of note; The check engine light can only be turned off using certain diagnostic tools, which can make it difficult to figure out if you've fixed the problem, so if you opt to purchase one, make certain that it has the ability to reset the light. Decent ones run about $50-$200.
What is the matter of check engine light on in suzuki XL 7 2001 obd2 shows p0440?
PO440 means the computer has detected a leak in the evaporative emissions control system.
Code P0440 could mean one or more of the following has happened:
- The gas cap is not installed or working properly
- The purge solenoid has failed
- The canister is plugged and not working properly
Possible Solutions With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
- Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
- Inspect the EVAP system for cuts/holes in tubes/hoses
- Inspect for damaged or disconnected hoses around the Evap purge solenoid
- Check and/or replace the sensor
- Check and/or replace the purge valve
- Have a professional use a smoke machine to detect leaks
What do you do when the maintenance required light stays on?
Most auto parts stores (AutoZone in the US) will read your codes for free, and attempt (sometimes successfully) to decipher them. They may not reset your Check Engine Light, but if it was a temporary condition, disconnect your battery for about a minute and reconnect it. This will reset the ECU.
If the condition persists, the Check Engine Light will come back on.
You can unhook the neg battery terminal for 5 minutes or pull the main fuse for the same duration. Either will clear the codes and reset the monitors. The thing is though, even if you erase a code, if it is recurrent, it will set the MIL light again. And when you reset the computer, it takes a series of stops, starts, cold and hot cycles for the car to relearn settings again. This relearning will prevent you from getting the vehicle to pass inspection, unless you hit the sweet spot when the majority of the monitors are reset AND before the MIL light illuminates again. Generally when I receive codes, I make note of them, and reset the memory and see if they return. Sometimes they do not.
He is asking about the Maintenance Required Light and not the Check Engine Light.
What does a blinking AC light mean on 98 Sienna?
If the AC light is blinking in the Toyota 98 Sienna, it means that something is internally wrong with your AC, it has stopped working, and it is recommended that you take it to the dealer to repair. This is not a very specific answer, but that is exactly what it says in the user manual. I find if I stop, turn off the car and AC for about 15 minutes, then restart, it will work again, until a week later and I have to repeat the process.
the answer u are looking for . a stopped up catalytic converter will not let the engine 2 create a vacume that cause your problem . it needs air flow to breath p.s yes it can and will
P0700 means EATX codes present. You need to have the transmission computer checked for codes.
Flashing check engine lights on GM vehicles indicate cylinder misfire. There are many reasons an engine may "run rich" but bad fuel/air mixtures will cause cylinder misfires. Also, unlike other trouble codes that cause the engine light to stay on, misfire detects are the only cause of a flashing MIL(malfunction indicator lamp). Therefore the ECM will read "blank" when you scan it. You may want to look at spark plugs and wires. O2 sensors may also be the culprit. Check your intake as well, if the engine isn't getting enough air, it may flood itself with more fuel to compensate for the power loss. And that will cause it to "run rich".
Service engine light on code reader won't read code any ideas?
Sounds like your ECM, the main computer on your car that receives messages from all of the sensors........ it might not be working. Or maybe the bulb for the engine light on the dash board is out.
I'm pretty sure that if the ECM is bad, your car won't work at all. Does your car work at all???
Probably a vacuum leak. Do you have a code P0171 or P0174?
What makes a 1999 Grand Am run rough and flash the check engine light on and off?
Severe emissions problem. Fix this ASAP.
To dig a little deeeper into the answer, It also may be a lown head-gasket. I recommend using a friend that knows alot about cars and buying the parts used. Letting a motor repair shop do it can cost you around $1,400!!!!!!!!
Could be a Sticky Egr valve. Replace or clean.
==========================================================
If the check engine light is flashing , that indicates that an engine cylinder
misfire has been detected . You can drive the vehicle in for repair , just avoid any
rapid acceleration or deceleration because you can damage the catalytic
converter - Helpfull
Why would a 1997 Jeep Wrangler have a random cylinder misfire?
if it is not consistent IE not JUST the #4 cylinder, I would look at the distributor (button, rotor, etc), Ignition coil and the wire connecting them
Also, check the fuel injection, if there isn't enough fuel to drive the cylinder it just sits there (this is also a common reason people fail their e-checks). If the check engine light is on it should kick out a 200 code for the above problem.
If the code is just a 300, I would start checking the distributor and wires as said before, and of course make sure the plugs aren't cracked. If none of that helps, it is time to take the head off and check the seals around the offending cylinder. I hope that is helpful to you! -Katrina
