OK as you know I am currently having fun and games with the idle on my motor.

 

As a side issue for today, I see the TPS (Throttle Position Sensor) looks like it can be fitted in slightly different positions on the throttle body as there are slots rather than bolt holes which allow some rotation.  Once the TPS has been removed how do I know where it should be positioned at when refitted and if it is replaced in a position which is a few degrees out is that likely to cause fluctuating idle.

I believe it can be set electronically but my OBD 11 reader does not work on this Pinin so basically I need to position this by "ear".

On the GDI ...

On the GDI engines, it can be adjusted using a DVM - I presume the same can be done on the MPI, but I don't have access to the details.

DVM

Several choices, Doctoc in Veterinary Medecine or Digital Voltmeter smiley

OMG.  Is that all.  I have voltmeters all over the place.  I find acronyms really frustrating.  DV = deep vein ******

TPS

Dude,

easy fix!!!

now i'm assuming correctly you have a MPI not a GDI motor - correct?

crack open the engine manual (13) and go to 13C96-13C97 for MPI TPS setting. The TPS is set by rocking it side to side (losten the screws a bit first) with throttle closed to set the base resistance.
TPS has a rectangular plug - pins looks like this:    [(1)      (3) (4) ]    the base-line idle value is in the manual. Pin 1 to pin 3 varies with throttle opening from low/closed to high/open. pin 1 to 4 reads maximum value same as throttle wide open.

(i did it here when fitting a strut brace http://pajerio.com/forum/bobs-io#comment-17746)

0.8Kohms i'm pretty sure is what you are looking for from 1-3 when throttle sitting closed.

this site (http://www.auslancer.com/forum/viewtopic.php?f=40&t=7391) also lists how to set the throttle stop with a feeler gauge if you've mucked around with it.

ALSO it may be an idle stepper motor however hopefully not - setting the TPS will take 5 mins, a new TPS from ebay will be about $20, a new idle stepper motor will be about $200 :(

First........I can't even find a listing for a TPS for a Pinin and something like this is close to the Mitsubishi EO price.sad   http://www.ebay.co.uk/itm/New-GENUINE-Mitsubishi-Pajero-i0-QA-1-8L-4G93-Throttle-Position-Sensor-TPS-/121003916317?pt=AU_Car_Parts_Accessories&hash=item1c2c653c1d.  I think it has gone wrong rather than needing re-setting

Second, I booked a full diagnostic test only a few hours ago for the morning as I am not 100% sure what is causing the fluctuating idle and I am now getting pissed off with it (but I bet it is the TPS).

Third, I have not touched the idle screw so I assume it will still be OK.

Last, thanks for the advice..............I think a diagnostician should be able to spot the fault and set it right if it is doable.

I could do with a idle sensor too........can you find one of those?  Nothing in this country apart from Mitsy dealers.

Arghhhhhh, incredible.

Just two minutes ago literally I bought one from the US costing...............$20 and the same for postage.  

 

If it is NAFF I'll come back to you.

 

I need to ask......................................Do you have the idle sensor?

I should have it.

The one you bought is new and the freight from Australia to UK would have been expensive. No much saving for you in that case and you will have a new one too...you are still in front :)

Need your advice!

Hi HELIJOHN!

going through issues with our iO as well..finding this thread extremely useful, could you kindly confirm if this would work on our iO? ('99 GDI 1.8L 4G93), saw this on ebay, we are currently guessing after actual tests and ruling out of other possibilities, that this might be the problem...i checked the part on our iO the slots are slightly different (vs "cross" slot on round sectionas shown in this item photo), hope to get feedback as our iO has been down for more than a month now:(, thank you in advance! Note: iOs were not locally released here in the Philippines, really struggling for parts and trying to know some reliable sources with good prices that would ship overseas

, thank you, really struggling as iOs were not locally released here in the Philippines:(

I'm really sorry but I can't help - it has been a long time since I had mine and I have forgotten most of what I did with the TPS.  

Also it was mainly actually because of this problem that I got rid of the car.  I sold it for next to nothing, gave it away, to a dealer just to see the back of it.

Idle sensor

OK guys, is this the right idle sensor do you think.

OK

if i am right - you have a 1.8L MPI engine - 

that makes you a H76W

TPS MD628074
idle solenoid MD628318 or MD628319

My car won't even idle at all

My car won't even idle at all when cold but when warmed up it's good ?? Went to mitsubishi and they told me there is some wax element inside the throttle body somewhere that needs replacing (sounded like crap to me).

yes sir - you have been told shyte!!

ECU regulates air through throttle to manitain idle via idle solenoid.

Fixed the idle prob's, got my multi meter and done the TPS and then took the idle valve thingy out of the spare throttle boby I have and changed all while the positive was disconnected and wamm all good apart from starting from cold it rev's at 2300 which is way too high until it warms up.

Still room for improivement then!  I expect I'll end up replacing bot TPS and IS.

You are correct, it is MPI.

 

Now then   idle solenoid MD628318 or MD628319 Is that Mitsy number or what?

MD628318 is the old one - was superceeded by MD628319 - both should do the same job

I can get either, I suppose the later one might be better.  They have asked me which so I'll take the ******19 one.

Hey Bob, what spray throttle

Hey Bob, what spray throttle body cleaner would be best to use, I have never used any before and what stuff do I use to also spray in the intake to clean the gunk from around the valves and stuff ?

sprays

anything EFI throttlebody cleaner is fine - and MAF cleaner for the air intake.

I also use once a year the "upper cylinder cleaner" spray that goes in the intake vaccum hose - compression in a can!

I use an EGR cleaner - I bet it is all the same stuff really.smiley

I add petrol additives for keeping jets and such clear of varnishing.wink

It would be nice to have a button on the dash that dispenses some STP into the air intake as I drive.  Nitrous reborn. lol

TPS MD628074

Well the TPS and IS both arrived at the same time in sparate boxes big enough to take half a dozen of each - such a waste on postage - so I decided to have a fit.

First on was the Idles sensor and a quick fire up..............oooops, idle shot you to an insane 3000rpm and stayed there. Could rev it up but not down.

Next the TPS - lost endless screws when taking the old TPS off - whacked the new one on, started it up and just the same, idle at 3000.

Then I took off the new IS and put the old one back but wait............the new one does not have a spring on it.  I had a choice of two part numbers (see above) but could only get the **********318.  Does this mean I need the *********319?  So fired it up and the idle is back to sanity even if not perfect at around 1000rpm.

 

I have yet to try it on the road but it looks like the IS that I boughtis no good to me.

Good tip

That's a good tip.  I can't recall if I did that each time but the idle speed defo improved when I simply cleaned out the sensor recess.
