My 2002 M Mountaineer had the same problem and was fixed by reading the code that showed a leak in the gas tank pressure via the cap. When I replaced this with a good after market cap and drove the car for a while and it cleared itself. A mechanic told me that's not possible, but it did clear and has not lit up except on start up where it lights for a few seconds to test the bulb - a normal function.

What does a Dodge Dakota Fault Code P35FE means or signifies


Generally, PCM (Powertrain Control Module) fault codes are showed as Pxxxx. Codes are displayed on the odometer.

On some cars, the codes will read out if the engine light is on - all you have to do is put the key into the RUN position.

Normally, to get codes, you put the key on OFF and then rapidly do OFF-ON-OFF-ON-OFF-ON (on some cars you have to do four or five, not three, OFF-ON cycles). To know about means description, visit OBD Fault Codes.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Error codes for 1991 dodge spirit


Turn the key to run then off, back to run, then off, then to run and leave it on. The check engine light will be on and will then go off and then on again according to the codes the engine controler happens to have in it. If the check engine light was on when you stopped the car, then there is at least one code in the controler. The light will blink the codes like this.
Cycle the key three times and leave on on the third time. light on for about 3-4 seconds then goes out for about 2 seconds and then blinks one time and goes out for 3 seconds this is for the no.1. Then the light blinks 3 times and goes out for about 3-4 seconds. You have the code 13. You could have a whole string of codes in the controler memory. It could be something like this. key cycled 3 times, light on for 3-4 seconds, then blinks 1 time, pause, 3 times, longer pause, 2 times ,pause 4 times, longer pause, then 5 times, pause 5 times the goes out.
This is code ; 13,24, 55. code 55 isn't really a code. It just tells you it's the end of any codes the controller has.
If you disconnect the battery and hook it back, you will have code 13 which simply mean 'battery disconnect'. It will errace it's self after several starts if it's not disconnected again. If you cycle the key and you get 55, this means there are no codes recorded at this time.
You will allways get 55 when checking for codes wheather there are fault codes or not. The light on for a few second before the codes start flashing is only a bulb check. Some codes like 13 will not turn the check engine on, but but will leave a code for diagnostic purposes only. If you have the check engine light on and accellerate and the light begains to blink, then the controller is telling you that you have an engine miss and are running the chance of burning out you're catalatic converter if you continue driving. Sometimes its advised to disconnect the battery after you have recorded the codes.
This will erase all codes that are present but were generated by conditions that aren't pertanent to the present condition. and then the codes that come back are the real ones to address.

MY 2004 MERCURY MOUNTAINEER ENGINES LIGHT IS SHOWING AND MY TRUCK HAS A SHAKE WHEN TRUCK IS TURNED ON.


Have the codes scanned for your engine computer to see what subsystem is causing the engine light to go on. One can do this for free at many parts stores.

Engine light is on but no apparent problems. oil OK. antifreeze OK. checked spark plug wires in front. had serviced last week. drove 250 miles to Tucson. drove a couple of days around Tucson---no problem...


you should be able to cycle key 3 times quickly to on position and the odometer will show codes. have codes read and find out what issue is it may be something minor but its best to know before it gets more costly

Will not start just died.


Engine? Those flashes should be 2 digit numbers . Cycle key, on, off, on, off, on & leave on & recount those flashes. Example: 3 flashes, pause, then 3 more is code 33. Or 2 flashes, pause, 4 flashes, is code 24. 5 flashes, pause 5 more, is code 55 which means end of message. Then get back.

In 97 mercury mountaineer, how to turn off "check engine" light


Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.

I know on old dodge products you cycled the key on and off three times then counted the blinking check engine light to determine the code.... yours may do the same...
