Car in "limp" mode

[nazGPX]

Before ignition

After ignition




The gear stuck in 3rd. i had searched the forum..some people got different problem when they are in limp mode e.g seal pump,ecu, n etc. while mine there is an oil leak..i'm suspecting its the atf. anything that i should check before going to the mechanics??

Yep, check the error codes

When in diagnositc mode, the 'N' light will flash a series of morse code. Just look up what that code is in the list in the link above. Will probably be an input or output speed sensor on the transmission.

hey Bennoz, i didn't quite understand how to do the manual diagnosis thingy..can i just split grey/red wires and get another extra wire then join them up and then ground the extra wire?

btw i just fixed the atf leak today. seems like there's worn out hose just a short length of hose near the bottom of the radiator and changed the atf oil but still i'm stuck at 3rd gear..

Just take a length of wire - can be speaker wire or whatever (I used a piece from a broken PC power supply)

strip both ends & attach one end to any bare metal part of the car .. theres a few spots under the dash to connect to..

Then take the other end & push it into PIN1 of the connector shown in the pic below (You might need to fold the wires back over themselves a couple of times to get it to the right thickness that it won't fall out);

okay got the time today to diagnose the problem..follow exactly the method of doing it but after i turn on the ignition the N does not flash and suddenly saw the 3rd was not on..start the engine and it was running fine..any chance that it would come back in limp mode?..any ideas of the problem??

A fuse can cause it to go into limp mode too, 10amp one inder dash

i have the check the fuse was fine..put it into ignition again it was stuck in 3rd again..and after i turn off the ignition there is "tick" sound in the floor console where the cd player are..need help here..

[Bennoz]

If you can't figure out how to check the error codes, then I suggest you take it to a mechanic.

Let us know what the diagnosis is, then we can take it from there.

So the car starts in limp mode? Or it starts fine and then goes into limp mode eventually?

I've found and fixed 3 causes when I'm had limp modes so far:

1) Speed sensor dead (Starts fine everytime then eventually enters limp mode while driving accompanied by a huge thud)

2) Blown indicator lamp fuse (10 amps in cabin fuse box)

3) Less alcohol (self explanatory)

It will go into limp mode if it has recorded certain faults a number of times. If you disconnect the battery for 10 seconds it will clear the faults and may just allow you to run the car for another while before it happens again. However use the time to either learn how to get the codes or to get to a mechanic.

that's the first thing i did which is disconnecting the battery..but after reseting the car it's still in limp mode which is before and after ignition and while driving which u can look at the pic..the mechanic here is a rip-off they charge 100 bucks just for diagnosing the problem..

i didnt check all the fuse though, i only check the A/T ecu fuse but found it was fine and there is no huge thud either while driving in limp mode..
