1990 Voyager. Need code definitions from check engine light. Codes retrieved by turning key on 4 times and counting check engine light flashes. codes were: 12 41 25 55.

Try this Turn the key on ( don not try to start), turn the key off, turn the key on, turn the key off, turn the key on and leave it on. If the check engine light starts to flash start counting the number of flashes. Those will be the codes. For about $50 you can by a code reader which will give you OBDII codes which may make it easier to figure out the problem. Post the codes and we'll see what we can figure out. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

• Yes you can retrieve the ODB codes. This one is not under the dash like so many. This one is under the hood. I am going to post a video that explains this is full for you. Your car does have a check engine light. So when you connect the key as shown then you will turn your ignition to on (not running) and count the flashes. The flashes will go in sets. Make sure to have paper and pen ready to write the number of flashes down. The video will explain this too.

• When you get the codes go to this page here http://www.freeautomechanic.com/diagnostictroblecodes7.html and you will see the reasons for each code and know what is causing your car trouble.

turn the key on,off,on,off,on,the check engine light will flash the codes.For instanse code 34 would be 3 flashes,a pause ,then 4 flashes.Will always have a 55 code because the engine is not running.

I have had same problem with my 1990 voyager .First have you retrieved the fault code ,by turning the key off and onwithin 5 seconds , 5 times ending up in on position ,then counting the flashes of the engine light. Procedure and codes are readly available online at this sight
I am 99 % positive you will find map senor is bad and needs to be replaced its located on the back of the manifold it has a three wire plug going to it it will cost under $40.00
they go bad quite often

You can read codes on the voyager by switching the ignition as follows

With the engine off switch the ignition key on and off three times in succession but leave it on on the third turn

Watch the Check Engine or Power Loss light. It will first turn on and then go out.
It will then proceed to flash out the error codes which can be read by counting the flashes and translating them into a number sequence.

For instance, if it flashes once then pauses then flashes 4 times this is number 14 code which equates to Throttle Position Sensor voltage out of range (Example Only).

Hope this answer helps. Please remember to rate my answer. Many Thanks

Do you know how to retrieve fault codes by cycling key, on, off, on,off, on, and leave in on position & count flashes from check engine light. 2 flashes , pause, 2 more flashes, is code 22. 3 flashes, pause 3 more, is code 33 etc.... Get back to us with those codes if any. By the way code 55 means end of message.

TPS throttle position sensor get new.
report.

3 times ..turn the key > off on off on off on .> then count the flashes of the light , flash flash pause flash flash , = 22 , pause , i think when you see 5 flashes pause 5 flashes , that means end of list . there might be multiple codes , have a note pad , you have to do it twice to be sure of the code(s) .

Check the enginer codes by turning the key off an on 3 times in 5 seconds. The check engine light will flash. Just count them. Note a short flash is a 2 diget number. It sounds like your TPS is the prob. Frankster016

I just ran into the same problem. Today my mechanic showed me 2 computers, one under the rug under the glove box on the floor. Lift rug and turn key on, not to turn car on but to just turn radio on, and see if a red light flashes on this computer. It should flash once when you turn the key on. If it flsahes more than that one time, count the number of times it flashes and then light will stop flashing and start flashing again. Count it thru a few of those times to make sure you have the number of times it flashes right. If it flashes more than once, this is called a code. Having a code means there is something wrong with car, your mechanic should be able to tell you what the code means. Mine was flashing 2X, so the code was 2. My mechanic pulled the corresponding fuse for this code, and held the fuse out for 10 seconds, and then put it back in, this reset the computer to no codes. He told me to drivew it home and then shut car off and then turn key on again and see again if any code was flashing. When I got home, no code was flashing on this computer. Good news, resetting it by pulling the fuse fixed whatever that computer was doing.

Secondly, he checked another computer under my pass. seat, to do this you need to turn key on, (do not start car), and you have to view this from the BACK seat, it should flash a red light once and then no flashing. Well, mine flashed 15X, so was a code 15. He pulled the corresponding fuse, held it out for 10 sec. and put fuse back in. It then showed no flashing except for the one time it is supposed to flash when you turn key on. He told me to check it once home, I did, and the 15 flashes (code 15) is back and what this means is I need a speed control sensor. And he said it definitely does whack out the tranny. So all I need is a speed control sensor, not a transmission replacement! Try this and see if yours gives you codes and if so, have mechanic pull the correct fuses and hold them out for 10 seconds and then put back in. Then drive your car for awhile, and recheck the computer modules again for any flashing lights (codes.) You may just need a speed control sensor!!
