Thanks Guys, It seems I am not driving my Lexus hard enough. ColinRA

Hello guys, What does the switch marked ECT and switches between PWR and NORM do. I may seem a bit dim but without a handbook it's hard to identify what this switch actually does while driving. My car is a GS300 Legato 1997.This switch is on the centre console. Thanks, Colin

Hi, Yes thanks.ENORMOUSE help.As you suggested right at the start the single wire with grey connector is for the rear sensor.The 4wire one in my manifold has been installed in error. The wiring for the front sensor is very likely the little brass ended wire I pointed at as this seems to emerge from the same part of the loom as your front sensor.Not exactly but very near.As you also suggested very early on that has probably been tampered with. My next step is to get 1 wire sensors and install them one at a time to see what happens. I'll post my experiences when I get it done.Thanks for your time and trouble, Colin.

Thanks,I've read right through that thread now.I look forward to seeing where these manifold sensors connect to so I can really dig about in the right area to find my missing electrics.Just to reaffirm my engine is 2JZ-GE. Thanks Colin.

Hi, Look forward to seeing your wiring later,thanks. Actually the sensor in the rear manifold is a four wire type. I have shown another single wire with grey connector that comes out of the loom near the distributor.No idea what that might be.The third little wire with brass push-on end in near the offside of the engine bay near the wing. Cheers Colin. That what I am saying mate, looks like you have a four wire sensor on the manifold, when it should be a single wire one that fits the type of plug you are seeing. I believe the the connector you are talking about near the discributor is the connector for the rear sensor. The other wire with the brass push on end is most likely where the other sensor (the missing sensor plugged with a bolt) has been cut off to splice it onto a universal type sensor. I will upload my pics later which may help clear things up a little. Hello Tigerfish, Really could use a glimpse under your bonnet.I finally got the CD-rom to go for wiring diagrams.It shows the two manifold sensors as 4 wire type but doesn't show where they connect to,so not much help.I'm stumped! Thanks Colin

Hello Tigerfish, I've been under the car now and seen the senser under the drivers footwell.It does have its wire emerging through a grommet so that ones OK. The one I am troubled with is on the pipe that has the three rear cylinders running into it and seen from above in the engine bay. There is another wire with socket that is unatached.A single wire about the area of the distributer emerging from the loom. Yet another small wire is unattached that along with the others I have photographed.If you would email me I will send the images to you.Thanks for taking the time to help me. Email: colinrarcher@hotmail.com Thanks, Colin. P.S. Should there be a lambda on the front three cylinder manifold.I have a bolt filling a hole but no senser?

Hi Stav, The system seems to have its cat in place(I think).I cannot find any wiring into which this Lambda could plug,and I have really searched.The lambda wiring section is quite short so it appears that another wiring section is absent. Thanks, Colin.

Hello again.Yes, the one I have looked at is the one after the exhaust manifold has collected into a single pipe. I will look for the wiring from the drivers footwell. I haven't located the other two so I will try to find those too.Thanks for your help.If I need a picture I will get back to you. Thanks, Colin

Thanks for rapid response.The lambda in question is the one on the exhaust downpipe. Lead just lies there not connected and there is definitely no other wiring it coulc connect to. Colin

Hello everybody. I am the proud owner of a GS300 Legato 1997 model. I have a problem with emmissions control.The lambda senser wiring,terminating in a grey socket with 4 wires is not connected to anything,nor is there anything in the engine bay it can connect to.It seems that I have some wiring missing.Does anyone know what the Lambda should connect to?Assistance appreciated. I have a CD rom manual but although I accessed it once I can't get it to run again so without printed info.available I'm stuck. Regards Colin

Hello folks, Just got a '97 GS300 but there is no CD autochanger.Can I fit an aftermarket unit or would I be better off finding a used unit.Either way I will have to get it installed by a technician. Thanks. ColinRA

Hello everyone, I'm a new member and happy to be a Lexus owner. I've just bought a '97 GS300 Legato which I am delighted with but it didn't come with an owners handbook. If anyone can help me source one I would be very gratefull.I would be very happy with a photocopy of another members handbook so that I can understand the functions inside and vital info like tyre pressures etc. Any ideas? Thanks ColinRA
