Default service engine soon light

I have a 1998 caravan, 129,000mi. The service engine soon light is on. Can I check for codes myself? Should I have a mechanic check the engine?

You can check for the codes yourself by using the key on/off method. Turn the key on, off, on, off, then on and watch the CEL flash. It will flash once, pause, twice, pause, then count the number of flashes following each pause. That will give you a number. For instance, just did mine, flashed 1,2, 3,1, 5,5. The 12 is always the beginning, the 55 means it's done. Whatever's in the middle is your trouble code. If you do this and post the code, one of us will tell you what it means and help you troubleshoot ideas to fix it. You could also take it to most any auto parts store and they can put a scanner on it and tell you what the code is.

Default RE: service engine soon light





seizing on Autumn Girl's concern, my 99 Caravan Sport 3. 8 with 200,000 kms has (i believe) original 02 sensors in.

there's a little too much fuel smell in the exhasuston cold start, and i'm wondering how good/accurate the electronic system is for detecting worn out 02 sensors. at that mileage should i just change them out anyway?
thanks alot,
Wayne in Calgary

It sure can't hurt anything to go ahead and change them out. You might actually get better performance and fuel mileage if you do!

Hello dodge drivers!

My 1998 Dodge Caravan is flashing a "Service Engine Soon" code of 1-2-1-7-7-2-5-5.
Anybody know what that refers to?

Thank you!

code 17 is the thermostat code, it means you engine isn't warming up fast enough. Usually a thermostat issue. code 72 I can't find, are you sure it is 72.

Default Immediately as odometer turned 100,000, "ses" light turned on

Is the "SES" light preset to go on as odometer hits 100,000 ? I have a well maintained 1996 Caravan(minivan)?

nope, probably have a code and sweet timing. If there is a code, you should be able to get it and let us know what it is.

Default Thermostat

Speaking of thermostats......I don't know if it is an isolated problem or not but I have a 2001 with a 3.3 and it wasn't heating up as much as I thought it should. I pulled the thermostat and it came out in a few pieces not as one unit, no wonder it wasn't heating up LOL

Default service engine soon light

Wondered what the CEL light is that I'm supposed to watch flash to get codes. Figured since it's dark outside, I'd be able to spot it quickly enough. Followed the "on, off, on, off, on" precedure but can't find any flashing light.
Maybe I'm doing something wrong with the key? Or just don't know what to look for.
CEL??
Thanks,
Rob

Hi Rob
Your van shows the P codes at the odometer, only vans and cars form 1982 thru 1995 is when you count the flashes on the ck engine lite or the power loss lite.

Still the same "Key" protocol, only messages read on odometer?
I'll check it out. Thanks,
Rob

Default code 72

this code is left off of many sites. It is actually catalytic converter inefficiency. However, I have found in the past that it is actually a problem somewhere else, such as spark plugs or wires, or something that is making the car run rough and too much fuel is getting into the exhaust.

43 - Ignition coil primary circuits and engine misfires. That code can be broken down to 10 more specific scanner "P" codes that will tell you which of the three coils has a problem or which of the 6 cylinders is misfiring. Head to an AutoZone for a free scan.

Hi,
The "service engine soon" light on my '99 dodge caravan 3.3L went on. I also notice that the transmission is not shifting. It is in 3,000 RPM at 60kph. I'd like to see the trouble code so I tried turning the key on, off, on, off and then on but I could not see any flashing light. Where is the CEL? Is it in the dash board?

Please help.
Thanks

Your transmission is in limp in and you need to get the codes out of the TCM. The only code you may get is P0700.
