    Service soon light check engine light same thing.Have you changed the fuel filter at all, if not i would start there. If you change it take the old one and hold it over a white piece of paper and shake it and see if you see any specks of dirt on the paper.

READING CODES USING MIL (CHECK ENGINE) LAMP

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.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. 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.

SOURCE: engine diagnostic codes

I don't have a dodge ram but the codes for the dodge vehicles where pretty much the same. For my intrepid the codes read for the following numbers

12 - Problem with battery connection (This usually happens if you disconnect the battery)
21 - Problem with the oxygen sensor circuit
52 - Oxygen Sensor signal input indicates rich mixture during engine operation.

It sounds like you may need to change an oxygen sensor. Hope this helps.

How do I pull the service engine soon code from my 1990 Chevrolet 1500? Thank you


The ALCL connector is located at the base of the dash usually near the steering column. You can use a paper clip to connect the A and B terminal togeather. The check engine light will flash or blink the codes. A example is one flash then a pause then two quick flashes is a code 12 which means no reference pulses to the ECM. The engine is not running. You pull the codes with the ignition switch on but the engine should not be running. Write back with the codes and I can tell you what they mean.

Service engine soon light is on 1999 Dodge Caravan. What does this mean?


there is some fault that the engine's computer is documentig, and you need to get the code by having the car's OBDII (on board diagnostics) port hooked to a scanner,
this can be done for no charge at most retail auto supply stores-write down the codes and post them on here for help.

If a Converter has to be replaced, in less than 12 years,you got issues,that should have been diagnosed and repaired first.

Why didn't you give us the codes, and some drivability issues?

What does the "service engine soon" indicator light specifically mean?


when the service engine soon light is illuminated in your vehicle, it means that the on board self diagnostic system has detected a fault either in the engine, transmission, or accessory controls. when this light is illuminated, it means that there is a code stored in the vehicle memory which can be extracted with a code reader. any garage should be able to do this for you. good luck!

My 1997 Dodge mini van will not start. When I do


The flashing check engine light would mean that the engine is misfiring, If you have a scanner, use it on the diagnostic port of the engine to check for the error code to get which cylinder is misfiring and if there are other errors that needs to be checked.

How do i clear the "service engine soon"


Disconnect the battery for a minuit and turn on the light's to power down any electrical power. Reconnect the battery and that should clear the "servie engine light soon",but if there are any DTC codes, the "Service engine light" will come back on.
On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the Engine Light. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports.

For GM domestic vehicles made before 1995, the diagnostic connector is located under the dash panel by the driver side. To get the check engine codes to flash in your dash panel, use a jumper wire or a paper clip and connect terminals A and B of the diagnostic connector. Turn your ignition key on with engine off and the codes should start to blink. All codes should start with code 12 which is one long flash followed by 2 short flashes. This code 12 means the diagnostic system is normal and will repeat itself continuously if there are no trouble codes. Otherwise, code 12 will flash 3 times before flashing the fault codes.

the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.

Good luck and hope this help, here is a link to the DTC codes. http://www.gmtuners.com/OBD1_DTC.htm
