No, not until you tell us what diagnostic code is set concurrent with
the check engine light.

I'm not a mechanic and don't have the equipment to read these codes. And, by the time I take it to a mechanic, they charge $70 for a diagnostics test to read the codes to find a $10 part is at fault. Is there a way to read these codes without such equipment? Without being able to read the codes, is there some general ideas of some of the things that only would cause the Check Engine light to come on after having driven down the road for at least ten minutes that I could check? One person mentioned that a bad gas cap could cause it and I did replace it to no avail. I do remember that the problem started shortly after replacing the fuel pump in the gas tank.

Got the ignition key to the vehicle? Then you have the equipment to read
the codes.

To check the computer codes:

With the engine off, switch the ignition key on-off-on-off-on,
leaving it "ON". Do not
go to "start", just "on" during this procedure.

Watch the "Check Engine" or "Power Loss" light. It will turn on, then go
off, then will begin to flash-out any trouble codes that have been stored.
For instance, if it flashes:

flash <pause> flash flash
<long pause>
flash flash flash <pause> flash flash flash flash flash
<long pause>
flash flash flash flash flash <pause> flash flash flash flash flash

Then you have a 12 (one flash followed by two) a 35 (three and five) and a
55 (five and five). 55 means "end of codes" or, if by itself, "No codes
stored. Check the codes and report what you find.

I never knew you could do that! I did what you said and the following codes were presented in order...

12
32
14
24
11
22
55

It will be interesting to know the translation...thanks for all your help!

Yep, I'd say you've got some problems with your van...
 >> Stay informed about: 1994 Plymouth Grand Voyager 3.3 "Check Engine" Lig 

Wow! I have a few things to look at to say the least. I know why the egr fault as the replacement engine (1992) did not have the egr hookup that my 1994 did. I'll give this to my son and see if he knows what to do to resolve these errors.

Thanks to all for all the help!! This is a great forum!!!

i have '89 plymouth voyager 4 cylinder non-turbo automatic. it has this problem. in a cold start i have to step on the gas continously to warm up the van or it engine stop. if i release the gas it just loses its power and dies. and after a long warm up and run it sometimes it jumps as if it is choking. as if there is no fuel coming in. i check the codes and it appear to have code 15 and 34. how can i solve them. im desperately need an answer. pls. thank you.

I had the check engine light come on with mine as well. No codes for
MONTHS. It was really ticking me off. Finally, I was getting
occasional spit-back and los of power.

I took it to my trusted shop. After a few minutes of tinkering, it
turned out to be the O2 sensor. I never did get a code, but all the
tech got from the O2 sensor was a square wave. This sqaure wave
averages out to a 50% signal. Sort of a "best guess". But the signal
did not change or track with varying engine conditions.

As soon as the new sensor was in, he showed me how the signal returned
to "normal" varying with conditions like opening the throttle.

The check engine light has not come on since.

A VERY quick, and relatively inexpensive fix. )

As reported earlier, there were several error codes present on the computer diagnostics some of which were due to changing out the '94 engine with a '92 engine. I have some things to look at bit interesting to note that I went to the state inspection center and there posted on the waiting room window was a note about "Check Engine" lights being on. Topping the list was the fuel cap not being able to hold pressure. How that relates to the diagnostics codes I don't know but without doing any changes, the light now sometimes doesn't come on on my drive to/from work. Interesting.

BTW...the car failed NOx (too high) and obviously they don't read the computers codes on some earlier cars otherwise they would have seen at least a dozen on mine. I have to find out how to reset the codes to get a fresh report.

Emmissions testing here NEVER reads the "codes" from the engine's
computer. They don't care. What they DO care about is the reading
taken from the "sniffer" that they put up the tail pipe.

They also care that all emmision system equipment that was "stock" is
there and functinoing.

And yes, they check the gas cap too.

My repair shop has a computer that talks to the computer in the Van.
Their computer can "clear" the codes. This is important since you
usually want to know what codes have appeared recently.

Many codes will appear, but will not always cause the "check engine"
light to come on.

NOx failed? wow. Never even came close on that one.

best of luck.

Yes they do care, OBD2. 1996 vehicles and up. OBD2 system include a monitor
called readiness codes. That indicates that all OBD2 tests have been
performed and passed.
Some states still do the standard tailpipe test on all years but will start
the OBD2 test soon

Oh just great! So now you have to pay for the test, AND you have to
pay BEFORE the test to have someone do the test that says that you are
ready for the test!

What a f'n joke. Typical government.

If the damn money wasn't coming out of my pocket then it would be
laughable.

Huh? In Our state, if your OBD2 readiness monitor has not completed because
of some reason such as a fault code was recently cleared and you go to take
the test...... they will tell you to drive the car a few days with a few
warm up cycles and then bring it back. Should only be one charge
