    If you go back to that site:
    then look under: TRANSMISSION/ TRANSAXLE 05
    ON-BOARD DIAGNOSTIC, click on 05-02.
    Look under DTC PO734, and it tells you to go to
    page 30. When you go to page 30, there are 11 possible
    causes for that condition, including ATX fluid low,
    solenoids may be stuck, etc.
    I guess you'll have to go thru the diagnostic procedure.
    I don't want to confuse things any further, but the air hose being cracked suggests TP or Speed sensor.
    I noticed when I got my scans done, some shops are
    better than others. Some places won't pick up all codes.
  • single female with dog moving across country. my o/d light was flashing on, a different feeling to the gas pedal so decided to pull over. my non-stickshift '99 protege LX w/100k miles was not shifting correctly, stopped at a gas station/service center at the last exit on the east side of albuquerque, nm; when i came back out after speaking with the tech. there was a "pissing stream" of tran. fluid coming from a cylinder about 8 inches long a few inches diameter with a band around it near my driver side tire. i'm pretty sure all my tran. fluid is out of my car. SO...what to do? no shop is open until monday and again, i'm moving across the country with no connections in new mexico. basically, any advise to who i should take it to and how not to be taken advantage of - like do i need a new transmission or could it possibly be something else by the above discription? i'd appreciate any help! -stuck in a hotel indefinately.

    The air hose is easy to remove- there's only 2 screws on those circular clamps, and just ease off the wires and things near the top. You can use duct tape as a temporary measure to seal the cracks. A brand new air hose is about $ 40. I asked my mechanic and he said the air leaking out could screw up the TPS or the PCM.

    I hope someone can help me here...
    my protege is having technical difficulties to put it lightly. the car would turn off while driving, I had to jump it 2 times to get it home. I bought a new battery for it, changed the spark plugs, ran for 3 days and then it wouldn't turn on and the battery was dead.
    I was told to check the alternator which I did...3 hours later it had been removed and checked at pep boys, after 2 tests it had passed. today I bought another new battery, new battery cable wires, fuses hoping this might be the solution...if anyone lives in the Philadelphia, Pa area..I make a mean [non-permissible content removed] london broil an baked potatoe and chicken parmesean! *hint hint hint*

    I have a 98 masda Protege and all of a sudden I can't even turn the key. Any ideas. The steering wheel is not locked.

    Hi sambo4

    Used duct tape to temporarily fix the air-hose. Seems to make quite a difference. Idling smoothly, feel lesser vibrations....need to change the hose soon though. Still need to get the transmission checked.
    Thanks for the tip...

    I recently unplugged the negative battery cable on mazda protege 200 to get the check engine light to go off. I was able to get the light to go off but the car runs like total crap now. I must have wiped out its running memory or something. Does anyone know how to fix this?? Thanks, Paul
  • vittuvittu Posts: 1
    I have a 2002 protege lx 2.0 with only 30kmiles my idle was recently
    Rough & low with check engine light on I had my egr cleaned out & smoothed out the idle but its still low only at about 500rpm b4 i was at least at 750 or so any suggestions. Thanks in advance.
  • jrdwyerjrdwyer Posts: 168
    Some possibilities: vacuum leak, malfunctioning airflow meter, crack in rubber air intake snorkel. Check for any TSB's on the subject at ($15 for a year).

    Also, if you take off the air intake snorkel, it is a good idea to clean off the throttle plate with an old toothbrush, rag, and solvent as it gets covered with black carbon over time.

    Can someone throw light on this please?
    The second fan doesnt come on, making A/C not so cold. I live in florida, so on a really hot day, the engine overheats with the A/C on.

    Technician said pressure sensor is bad and not easily available. Can someone point to aftermarket pressure sensor and/or another solutions

  • sambo4sambo4 Posts: 22
    I have the same problem with the secondary fan, which is the passenger-side one. It's only to come on after a certain temperature is reached.
    I removed the fan and tested it, and it does work.
    Just connect one wire to each of the battery terminals,
    and then the end of those wires into the fan connection.
    I didn't know which was plus or minus on the fan, but it's only two choices.
    My fuses are okay too.
    My next step is to test the wiring harness that goes into the fan.
  • essennessenn Posts: 7
    the fan itself is good. technician did directly give it power and it blew decent amount of air. although i did notice most of the harness/connector are rusted, but he didnt think much of it.

    btw is it pressure switch or temperature switch or both?
    i see two sensors near the bubble window on the A/C line,
    on left front fender. dont know which one of these to jumper.
    can this be replaced at home or does the freon have to come out first?

  • sambo4sambo4 Posts: 22
    I was reading trouble-shooting possibilities:

    "condenser fan relay is stuck"

    "short to GND between condenser fan relay and
    PCM terminal 45"

    "circuit between condenser fan relay and fan motor short to battery supply line"

    Hi there,
    I have a slightly different problem on my 96 LX. The engine temp goes all the way up to 'H' when the ac is working. I have to shut it down then the temp comes down a bit, but hovers around 3/4 way to the H mark. Coolant is at the right mark. Also, can we check the gas level at home. The AC though seems to be cooling alright. Problem is worst in city traffic. Do u guys think there is a prob with the radiator? There is no leak in it.
    Please advise what can be done :sick:
    Thanks in advance!
  • essennessenn Posts: 7
    its the same problem with mine. A/C works but engine overheats (ie goes to H) on a real hot day...try putting A/C on max, open hood and see if second fan comes on after a while...if it does come on, then the problem is different...

    when car is around 50 mph its not a problem bcoz the air hitting the condensor from outside will be enuf to cool it, mostly...
  • essennessenn Posts: 7
    btw, my car is 92 mazda protege LX, 1.8L DOHC w/ automatic xmission...
    thanks for the trouble-shooting tips...i'll try them out...

    I'm a relatively new '03 Protege5 owner. The A/C intermittently flickers on and off when the fan speed is on 2 -- it works fine on 1, 3, and 4. The problem appears to be more frequent on hot days. (Of course, the day I take it to the mechanic is the coolest this summer, and they couldn't duplicate the problem.) Any ideas as to what is going on? Car has 42k.
  • sambo4sambo4 Posts: 22
    Try this site concerning relays:

    I'm still working on my car.

    I don't think the pressure switch is involved, because that switch monitors head pressure and shuts down the compressor if it exceeds a preset limit.

    You can also try unplugging the clip from the thermoswitch
    located on the thermostat housing. If the fan goes on, then you found your problem. If not, then I still think it's your relay, or a connection problem.

    You could switch the condensor fan relay with a similiar relay, (maybe the horn relay ? ) just to test it.

    Also, check for corroded relay under the fuse box and support wiring/harness.
  • katek8katek8 Posts: 2
    i had a similiar problem. although mine would stop working on the highway, driving 75 mph, 17 mile trip to work. At first it would work intermittently for a while, and the mechanic couldn't find anything wrong. It ended up being the thermastat, check to see if it is higher than normal. the car finally one day almost over-heated and the problem was solved w/ the a/c.
  • sambo4sambo4 Posts: 22
    Forgot to mention:

    I'm not too familiar with '92s, so you may have to
    ground the thermoswitch connector, either to chassis or
    negative battery terminal.

    good luck

    I have exactly the same problem on fan speed 2 when it is hot. Makes no sense to me. It is not overheating.
  • Hello,

    I have a 1997 Mazda Protege LX 1.5L

    When I first bought the car the seat belt warning light and tone would operate properly when you turned the ignition. Now a few months later the light no longer comes on along with the tone, I saw the connection from the seat belt fastener to the floor of the car under the drivers seat and that is properly inserted, does anyone know what else I could try to look at? I also checked the fuses, they're ok. Another problem is my low fuel light to my knowledge has never worked correctly, is there anyway to check if it's just a bulb out or if the problem is more significant? Thanks!

  • essennessenn Posts: 7
    check the key might have broken off some 'teeth' in it...(HINT: compare with the same size spare)
  • essennessenn Posts: 7
    look at the engine light when it stumbles see if it flickers. get the code out of computer (thru diagnostic connector behind battery on my 92 protege)....problem with engine light is its on only while there is malfunction, but it stores the code in computer anyway, so you'll get the code

    mine did similar thing for a month, also started stalling...can get very dangerous bcoz steering locks up on turns...i got the coolant sensor changed, problem gone.
  • kjohnson7kjohnson7 Posts: 1
    i have a 1997 mazda protege with the 1.5 DOHC. i am replacing the engine because of high mileage and i was wondering if any one knows of another engine that fits that car. kinda like the civic and the integra swap every one does. or maybe of just some engine mods you can think of. i mainly deal with hotrods and domestic v8's so this is my first import. any input would help greatly. thanks
  • jrdwyerjrdwyer Posts: 168
    1.8L from the Protege of the same year for more horsepower and torque. I believe it is the same as the MX-3 1.8 liter. Lots of modifications are available for this engine.
  • jrdwyerjrdwyer Posts: 168
    Make that the MX-5 Miata with the 1.8L. The MX-3 had 1.6 and 1.9 liter engines.
