Accelerator paddle

[Kamsin]

Has any one got an accelerator assembly for a Maverick/Terranno 2 they dont need. Iv been told the juddering on my truck at around 1,000 rpm could be the electric control on the peddle mounting. If some could lend me one to see if it fixs it, that would be great, i dont want to go buy one and find out its not the fix. If it does work im happy to buy it from you! :augie

Many Thanks.

(PS That should of said Peddle)

have you given the microswitch a clean?

 

[Kamsin]

Iv not done anything with it at all. did not want to mess it up and not work.
Is it a simple job to do? Any help on this would be great. :thumbs

I have sent you a PM mate. two things to check, microswitch behind the pedal and the control box at the top. clean the microswitch, check the control box is tight, and both plugs are attached and clean....

just thinking would it be possible to check the voltage output of these switches , just like the check on the maf . to determine if operating correctly ? does anyone know .

Pages EC-365 onward describe the test procedure for the idle switch etc..

Hi I suggest that the juddering is the transmission, changing down a gear will cure it, my terrano
will not run at such low revs, unless I am in first gear. regards bri

Iv just read all this and to be honest, i think this is going to beat me. I have no idea what im doing with this kind off stuff. Im going to have ago in the morning, but have a feeling the truck wont be running by the afternoon. Fingers crossed.
Thanks for the help guys, its better than going in blind.

Kamsin, tomorrow I am taking my pedal assembly off to attempt a repair, as I have an issue with mine. I will try feedback my findings to you as quickly as I can. My plan is to actually open the microswitch to clean, check the wires, plugs and connectors and then check the TPS (top of pedal) as I believe it is this that sends the position to the ECU....apparently a good clean may help.;

Cool, was going to do mine today, but will wait to see how you get on with yours. No point in us both doing something stupid and removing a cover to see all the bits explode all over the place . As they say, For warned is pre armed! :thumbs
Good luck, i await with baited breath! :naughty

It dont matter what gear its it, at 1,000 rpm it will judder. Had the transmition checked out and found no fault. Have been told now that lots of Terrano and Mavericks on the peddel. :doh

Any thing is woth a try though!

ok, arsed about all morning trying to resolve my issue, no joy. Took the pedal out, and gave everything a clean. Only thing I couldnt do, was take the microswitch apart, and the TPS apart. Very easy to do, but for me, achieved nothing. My issue is different to yours though Kamsin. 1k rpm juddering doesnt make me think its the pedal now though...I dont see how it can be? for example, if its the pedal, then I would expect revs up down up down in line with the juddering, any of that?

The microswitch only indicates pedal on or off, so for me, when I very lightly push my pedal, and release the microswitch, the car is OFF LIKE A SHOT. The TPS then indicates pedal position, for example, I adjusted mine today, and ended up idle at 1.5k rpm, re positioned TPS and all is normal. I also noted that on the pedal assembly is a small screw adjuster for the [pedal position, adjusting this cause the pedal to randomly stick on, as it didnt fully reset, again I had to readjust the screw to allow the pedal to reset back to its rested position.

sorry Kamsin, no joy from me, but as its easy to take the pedal off, it may be worth giving the TPS a squirt, bear in mind that its just a sealed unit, with a small metal jobby inside that the pedal attaches to to turn it...I sprayed that, no joy.

can you describe the juddering, in fact, can you video it and post?

when u say juddering would u describe it as missing on 1 cyl

The juddering feel like a loss of fuel as if its going to conk out, if it starts juddering and i floor it, then it picks up and drives with out a problem. It only happens at low revs, so you notice more if you slow down for a corner and have to power back away, it you change to a lower gear then it wont happen as the revs stay higher.

I dont think its an "Air" problem in the line either as i had it before i did the fuel filter and its just the same now. i have cleaned out the MAF, changed all the filters and all the oils. There is NO banjo filter as i had also looked to see if that is it too.

Im running out of ideas, a friend of mine has told me that Terrano and Mavs had problems with the peddel and they had to be replaced, his gues was that was the next place to look.

The truck drive fine in all gears but acts the same in them if the revs are around 1,000rpm if you drive normaly, if you boot it its fine!

odd, im not yet convinced its the pedal, but I am open minded. To me, if it was the pedal, you would be showing a code on the MiL, its electric, so its all voltages, anything that would cause a judder at a specific rev would surely be voltage related?

check the CKP sensor would be my next guess. Can you verify if it judders when cold, or is it when at operating temp? Also, question the No1 injector, thats got a sensor on it, its right at the front under the I/C, you can see it if you shine a torch in there, check for leaks, check the plug. also, you can see the other injectors through various crevices, check those and especially the rear one.

Another thought is EGR, mines got one, so, has yours? Its right at the back of the engine, under the I/C, a pipe comes out of it, over the engine block to the solenoids under the air filter.

its all very easy stuff to check, so dont be bewildered by it all!

Hi mate, it does it if its hot or cold. I will check round the injectors tomorrow. It has got the EGR on it, i was going to remove it but could not work how it comes off, and if i take it off will i need to blank anything off. :lol

Iv fixed every problem this truck has had sine i got it myself, but this one is beating me.:lol

 

[clivvy]

there is an EGR guide in the downloads section. I didnt remove mine, just blanked off the pipe at the solenoid and and at the egr end. The proper way is to take the egr off, and insert a blanking plate, or replace it.

Have you read the codes? Anything stored in memory? Does it idle correctly at around 750rpm? does it judder if you press the pedal not in gear, or is it alwasy when its in gear?

Dont have anything to read the codes with. Yes it ticks over at about 750rpm with no problems at all. I have disconected the vacume pipe from the egr but its made no difference. It only does it when your driving, out of gear it will run at what ever revs you want (I think, will double check this as well)

ah right so juddering underload.

to check the codes, you need a paper clip....there is a guide in the downloads section, and its very easy to check. even though the MiL light is not flashing, you may have a stored code which MAY give you some clues....

Ok, i will have a look at that next. Well Tomorrw, :lol

I have feeling that the bulb is missing, i remember seeing some missing when i put the 4x4 bulb in. wonder if it was taken out for this reason, the 4x4 was not working so when i got it so this maybe a clue, Thanks.
