Replaced TPS and hoses, still Engine light and idle probs - Page 2 - Land Rovers Only

UsedBlue · 05-06-2008, 01:45 PM

actually I am a woman- but thanks so much for all your help on here!
I just bought the new stepper motor for $33 at advance auto for the v6 astro van. The one for my Disco was about $185. Now, we'll see if it works once I get it in there.
Thanks again!

A code 48 is set when the computer wants to see a Idle speed and for whatever cannot get it.

This can be a Iac motor. Or Unmetered air getting in the intake, or even a stuck timing advance can cause it. The TPS was a waste of money if your diag proceedure for this concern is Swaptronics.

A $38 high failure part is a good start but not the only cause.

Be advised. On a 95 Disco, you can clear the code by pulling the "Fuel Injector" fuse for 10 second and reinstalling. This fuse is located in the underhood fuse block.

So what is the outcome after replacing the steeper motor?

UsedBlue · 05-10-2008, 01:54 PM

we did just now put it in and pull the fuel injector/pump fuses- it seems to be okay besides the #02 the display is showing up. It was #48 for the idle and now the code 02 is showing. that is why we just jumped on here to see what is wrong with her now!
The Check Engine light is off for the moment- but the speed sensor isn't working so I'm not sure if the light will come back on for that.
We are now looking for a new muffler- she cracked all the way around just after the clamp, after the cats- thank God- and now my shifter area is getting really hot. We looked for the shield and couldn't find one - i thought it was supposed to be above the front muffler area and it isn't but we've never had a heat problem before the muffler went bad.
So, we're going to check code 02 and see what that's all about.
I'll post again after we see if the new stepper motor fixed the stalling problem. It only stalled when i was coming to a quick stop and right off the highways too. fingers crossed!
thanks again to all for the help!

Code 02: Battery Recently Disconnected

Code 02 indicates that the Engine Control Module (ECM) has just been reconnected. Switch the ignition switch to position II to clear code 02.

UsedBlue · 05-10-2008, 07:37 PM

ok- did that and now there are no codes at all- so far.
i will update to when we see if that Astro van's AICV worked!

Rovin4life · 05-10-2008, 07:37 PM

only the dealer can clear the code for the SRS.

you need testbook plus a special adaptor that hooks to the system and the battery.

UsedBlue · 05-10-2008, 08:36 PM

so, basically the SRS just needs inspected?
The last 'S' is flashing now and then. It has been going on for at least the 2 1/2 to 3 years we've had her!
I would hate to have to pay the dealer hundreds basically to just turn out a light that has always been there- unless it really is a good idea to do so

Phototone · 05-11-2008, 09:51 AM

As I understand it, the SRS (airbag) light comes on after 10 years, regardless. It then has to be inspected by a dealer and if any parts are defective, those need to be replaced. If your truck is older than 10 years, it doesn't mean that anything is broken, it just means it is time for an inspection. That is what I understand.

No, the system comes on when it sees a problem. It lights up for a second to do a self check at startup, if there is a problem like a loose connection or excessive resistance or low battery voltage the light will activate.

To clear the light the dealer hooks up a special connector to testbook to read the codes and then they can clear them to see if they come back. Takes only .3 nothing more. If it comes back well then the diagnosis needs to be done.

UsedBlue · 05-11-2008, 01:55 PM

does any one have a clue as to how much this test may run me- cost wise?
I see a lot of replacement parts that are used for the SRS system in case a part IS bad- so even if they tell me there is a prob- i can try and fix it myself.
Is this self fix on the SRS system advised for the Discos? or is it way too hard. I have good mechanical knowledge, it's just the Land Rovers I am still learning about.

UsedBlue · 05-12-2008, 06:31 AM

the new IACV from the 1998 V6 Astro Van is working just fine- no more dips in the RPMs when I am coming to a stop. The Check Engine light is still off at the moment, but we're having trouble getting the new speed sensor in- it's so tight and we're not sure the little pin part is actually in the right place so the Engine light should reappear if the OBD is working as it should.
I saved about $140 by not buying the Land Rover part.

UsedBlue · 05-14-2008, 10:37 AM

Okay- the Astro Van stepper motor worked nicely for a few days- now she is not even wanting to start up at all until after 4-5 tries. The Engine light went off and the OBD cleared up, but somehow she's still idling bad and even seems worse at times. I ordered a nice used stepper that is actually for a disco I from Paul Grant so we'll see if that makes any difference- we're running out of ideas! The TPS was replaced, the hoses and the stepper. We read in a few places that the Astro Van's stepper was cheaper and worked just as well..... we'll see what happens

Paul Grant · 05-15-2008, 09:00 PM

I meant to ask you the other day, what spark plugs are you using?

UsedBlue · 05-16-2008, 06:25 AM

i am not positive, but i think they are Adelco or something like that- just the cheapest ones and we just had them replaced.
