Tip box problem?

[power]

hey, been having trouble with what i think could be the tip box. recently when driving if i put the foot down to get it past say 3000 - 3500 revs the car starts jerking rapidly and the rev needle jumping up and down! But if i drive with a light foot it doesn't seem to act up! The engine light has also come on once or twice at random intervals.

After searching the site i thought it could be either stepper motor or ecu, so i reset the ecu twice and cleaned the stepper motor (and also checked the gear box oil). Still no Joy!
This ever happen to anyone? Could a worn gasket on the inlet manifold cause this sort of thing? Or is the tip box jus gone?
Cheers for any help on this

Could be a number of things, need more info to assist.

You've confirmed that the ATF is within the required threshold when hot? (check when in park). When was ATF/filter last changed? Any jerkiness from the box when moving between park/drive/neutral etc? Does the box ECU ever go into limp home mode (flashing N)?

Fuel filter - possibly blocked, consider changing.

Plugs / leads - changed / checked?

Undertake a diagnostic check (search for info) and report back on the outputs from both the engine and 'N' indicator lights.

Cheers CJ, will try the diagnostics and see what it gives me!

When checking the oil i warmed up car then turned off the engine with it in park gear, the oil was about quarter of the way into the hot section of the stick.
Is that the proper way of doing it?

Done the diagnostic test today and got error code 14, which is throttle position sensor!

Where is the sensor located? And is it an easy thing to change? Thanks guys

Can someone sticky the diagnostics thread in the KB? Might make it a bit easier to find when someone asks.

[power]

Ok i've fit the new TPS, reset the ecu, and cleaned the air filter and its still Doing it!
I'm thinking of changing the fuel filter, but the diagnostics is still giving me faulty TPS. Could the diagnostic be wrong? Could something else be causing it to give out this reading, or do i have 2 faulty sensors?

[colm_mcm]

Doesn't the TPS need to be calibrated before fitting?

[power]

how do i do that?

[power]

does this apply to the tps on the fto? I found it on a honda site

[CJ]

how do i do that?

Its been discussed on the forum in recent times, search for 'TPS'.

yep found a post with Rory saying he used a multi-meter to check a faulty TPS.
Maybe he can confirm which pin on the TPS to put the multi-meter to?

[steelroe]

Will look at wiring diagram again and see which pin it is. I pinned it out at the ecu but you can do it at the sensor (smae thing).

I suspect a problem with the torque converter here. Sound like it is faulty under power and that is why the revs are going mad

[Gerry]

Does sound like a gearbox/torque converter issue.
Just to confirm,
when you undertook the diagnostic test, does code 14 flash from the N light in relation to the gearbox or code 14 in relation to the engine management light?

[power]

I was counting the engine management light, the N was blinking too but i didn't count it.
I didn't realise they were 2 different readings?

[Gerry]

HI,

Sorry to lead you astray power,
Just checked the workshop handbook, engine management light is the one ur looking out for.
Check out section's 23-12 and 23-13, in workshop manual, there is an diagnoses procedure in relation to
error code 14.

[steelroe]

Engine Management light blinks engine fault codes and the "N" (neutral) light blinks the tip box fault codes.

[power]

Well i'm not getting any codes since I reset the ecu at the weekend, but problem is still there unfortunately
Is there a way to check if its the torque converter giving me problems?

[steelroe]

TC test procedure

[power]

Done the Torque converter test today, 2500 rpm in both D and R. So I think thats ok, the engine warning light came on while I was doing it
and I got code 14 again!

right i had sort same issue when i bought my fto it was a manual i could only drive it in a certain way at first it would only work with the maf unplug but it was drinking fuel i thought it was the wiring as guy i bought it of was a fool and he hack the loom but also my rev counter did not work so i decided to trt somthing new i unpluged the ifs sencer and put maf back in brilliant everything went away it drove like it should witch is weird as normally the car will not start without the ifs. give it a try thow even trying a diff ifs may solve it. the issue i got with my car was if i booted it it would jurk but if drove it normally it would ressist up to 2000 3000 rpm befor it would jerk madly but the rpm i was doing is a ruff guess as i had no rev limeter at the time . and i no this may be no help what so ever but gf had slight same issue but on complete diff car it was a renault clio please forgive me for swearing lol and i solved this issue by changing complete throttle unit witch would relate back to fuel as it was spi and tps sencer witch u allready done so may be try looking around the fuelling system even if this is your last resort maybe presure regulatot is dodgy hope this helps let me no what u find

[CJ]

Power, did you calibrate the TPS? Generally, placing the new on in the same position as the old is enough but sometimes the tolerances can be out. Also, have you checked the wiring to the TPS? The wiring can sometime break where is connects to the plug.

I'm still waiting on my friend who's an electrician to come over and help me with his multi-meter, hopefully de weekend! Let you know how it goes
I'm really hoping its just a matter of adjusting the TPS

[power]

Well i've had the car in the garage the last 2 weeks now and the mechanic has confirmed its not the throttle position sensor! He's checking a few other things and this evening he asked me if I could get a lend of an air flow meter. Anybody have a spare one of these I could borrow for a couple of days? I've already bought two Throttle position sensors, so wanna make sure before I buy another part!
