bartkat Posted January 14, 2008 Posted January 14, 2008 Oops, sorry, I just read Bartkat already got that for you. We was busy being geniuses simultaneously.
smooth1 Posted January 14, 2008 Posted January 14, 2008 I wish more people posted thier issues like that. It sure makes it easier to help!!!

bartkat Posted January 14, 2008 Posted January 14, 2008 OK so check these pics..Should the one in the first pic go where....I am so lost here guys sorr y There should be no hose where that one is now.
smooth1 Posted January 14, 2008 Posted January 14, 2008 Click here and look at post number seven http://us.lexusownersclub.com/forums/index...showtopic=43436 I think the hose you have on the red arrow where there shouldn't be a hose goes to 90910-12220 in the diagram.
gunni Posted January 14, 2008 Author Posted January 14, 2008 Ok so I´ll take that one off..but are these then right ?

Reach or look under the airbox and you should find empty fitting(s).
smooth1 Posted January 14, 2008 Posted January 14, 2008 the little hose you have on the engine in your picture number 7 with the red arrow that points to it. That hose I beleive goes to the air box, and not to the metal hose looking connector. Both of the black metal hose connectors on each side of the cam box have nothing attached to them.They are just there and left open.
bartkat Posted January 14, 2008 Posted January 14, 2008 I'm getting dumb too. I haven't even looked under the hood of a IS300 for over two years.
gunni Posted January 14, 2008 Author Posted January 14, 2008 So I will remove the hose on the metal connector.and leave the other one like this ?
bartkat Posted January 14, 2008 Posted January 14, 2008 So I will remove the hose on the metal connector.and leave the other one like this ? I think so. There should be some clips or whatever to hold those items to the airbox or next to it. So except for the strange IAT reading you should be in good shape.
gunni Posted January 14, 2008 Author Posted January 14, 2008 Ill check this out tomorrow its 4:30 am here where I am and rise and shine 7:35am I´ll keep you guys updated tomorrow about how it went. Thousand thanks to you guys...
gunni Posted January 14, 2008 Author Posted January 14, 2008 Hi guys...Didn´t work...I was wondering do you know how I can check the MAF connector to see if there is a fault in the plug ??? The MAF is good and I can see the IAT sensors the are also clean and Good....
smooth1 Posted January 14, 2008 Posted January 14, 2008 did you check the connections and the wire conditions? I was thinking you had a short somewhere in the wiring, not the sensor itself, or a bad connector plug.
gunni Posted January 16, 2008 Author Posted January 16, 2008 DO you know how I can check the connections and the wire conditions??
gunni Posted January 19, 2008 Author Posted January 19, 2008 did you check the connections and the wire conditions? I was thinking you had a short somewhere in the wiring, not the sensor itself, or a bad connector plug. Can you give me some advise how to check these things or just where to start ??? Thanks
smooth1 Posted January 20, 2008 Posted January 20, 2008 Best way is to start with a voltmeter and check it at different points. Check the conitnuity, and make sure you have resistance at the sensors and MAF wires.
smooth1 Posted January 20, 2008 Posted January 20, 2008 When you replaced the MAF, did you also replace the IAT sensor? The IAT sensor is mounted on the mass air flow meter. Maybe that is your issue. The IAT is also connected to the ECM. I'll bet you have a short circuit in your IAT.
gunni Posted January 20, 2008 Author Posted January 20, 2008 Is a wire diagram available somewhere or does it even exist ?????
bartkat Posted January 21, 2008 Posted January 21, 2008 I found the test specs for the MAF. Attached here. I'm still digging for the IAT. The CD I have isn't indexed. Sorry the two are duplicates but it should work. insp.pdf insp.pdf
4.0 LS TECH Posted January 21, 2008 Posted January 21, 2008 hey bartkat where did you get your CD from, ive been wanting to get one for my ls but not sure where to go for it. I heard the ones from ebay are usless, i dont care if its indexed or not.
