Ok, according to this page http://www.lextreme.com/Lex%20DxCode.pdf Code 14 means IGNITION No1 Code 24 means INTAKE AIR TEMP SENSOR Code 41 means THROTTLE POSITION SENSOR. No idea what 14 means. I'm assuming the igniters are wired correctly as it runs with a bit of revs under it's belt. I...

OK. Threw the following codes. 14 24 41 I am searching at the moment to try to find out what they mean. Engine is from UZZ31 soarer.

Set the TB by removing it and turning the TPS till it was open circuit between IDL and E2. Didn't use feeler gauges as 1. I don't have any and 2. the Toyota tamper proof paint was still intact. I am going to head out now to try it again though, just to be sure.... Thanks mate.

Cheers. I have changed the coolant temp sensor now with a new one from Toyota. Old one was reading 1700ish ohms and the new one measured 1400ish ohms. Fitted everything to the engine again and it's the same. Injectors have been cleaned with new o-rings and i'm sure there is no air leaks...

More ISCV questions (sorry) **NOW GENERAL IDLE ISSUES** Ok small update. Fixed run on problem. As CJSUPRA90 said, the ignition and injectors were frd from the MREL. I still however have a dog of an idle problem. Starts fine first time, but immediately falls into a very low idle. after it goes...

New they are $320 and i'm only trying to faultfind an idle problem. Looking for a cheap secondhand unit.

I urgently require the water temperature sender that's located under the drivers side coil. Part number on mine is 89462 20030 Like I said I need it pretty urgently. Am happy to pay for freight etc. Cheers

Cheers for the help CJ, to answer your early question, yes this is a swap, but the ECU-engine wiring was untouched, as per factory. I have double checked the wiring and i'm sure it's right. After work I put everything back together and fired the engine. The engine now idles VERY low and runs...

OK thanks cjsupra90. Is the 3 second delay the same every time? ie, if I turn the ignition on and off, a few times, will it stay on for 4 seconds every time? I have identified a wiring problem where the EFI relay was fed with ignition power instead of a constant 12V supply. When I turned the...

Ok having a little more of a play and it seems the ISCV isn't faulty at all. I didn't realise you need to pulse S1, S2, S3, S4 and then repeat the process to make it open/close all the way (I had to repeat it some 15 or 20 times) If this is the correct way it is mean't to operate, why was it...

As title, need a new, or good condition ISCV urgently. It's the older type that you can pull to bits. Thanks

I am in the process of fault finding an idle issue with the 1UZ and have traced it back to the ISCV. I now have a few questions. 1. When I test the ISCV as per the manual (pulsing in sequence S1, S2, S3 and S4), the valve doesn't move at all. It feels like it tries to move, but doesn't. Is it...

Here's a pic. It's roughly in the middle of the pic, you can see one of the ports has a plug on it. Cheers

Hmmmm ok. On the passanger side of the engine (Aus), mounted on the plenum, towards the rear of the engine, is a small black sensor with 2 tubes coming from it. Can anyone tell me what it is then....?

Hoping this will be a quick one. Can anyone tell me where the 2 tubes on the MAP sensor go? I have searched for days, and can't even find a picture to help me. I am thinking I might be able to plug one of the holes up....? Cheers!

Thanks guys good info. Sideshow, the landcruiser originally had a plain old 1HZ in it, and is late 1996. Will I need one of your flash converters? If I use yours, can you assure me it'll work? Not worried about it being perfectly accurate, just within a few hundred rpm across the rev range...

Cheers for the reply Rod, Haven't checked for adjustability in the current tacho, but I would be very suprised if it was. These things only ever came out with a six so I doubt Toyota built in some adjustability. Worth a check though. The Jaycar unit would be great, but I have nothing to check...

Have a HZJ75 landcruiser fitted with a 1UZ and am just wondering what's the best way to correct the taco? Is there an off the shelf box of tricks I can buy? thanks

Have a look at my thread here http://www.lextreme.com/forums/showthread.php?t=11125 This will tell you everything you need to know to get it cranking and idling. Cheers

You need to switch 12v through to the STA pin only while the engine is cranking over while starting. The ECU will do the rest.
