wussup everyone just bought an is300 first lexus so dont really know to much about them and need some help.....

rpm and speedometer not working why? maybe speed sensor where can i located it looking down at motor

trac light blinking on and off with check engine light why?

nd looking fo 02 sensors but seen at dealer cost alot nd i think i need all 4 is there anything else i can do and will it have and effect on car if not changed and can i do one at a time

 

the speed sensor located at the transmission, it plugged into it you can ask the tech.
For the check engine light and the oxygen sensor.....hehe, big money bro, if you dont change it, it wont affect too much except drinks more gas than usual.

 

thanks......

 

Welcome to CL, hope you solve your problem! Good Luck

 

hope so 2 lol

 

ok checked back of cluster missing bulbs got bulbs nd have alot of lil signals comin up , cluster doesnt light up at night rpm and mph not working, nd i also want to get o2 sensors changed can some1 help me out where 2 start one good thing is car runs good

 

if you dont change the o2 sensor then it will burn rich, but if you dont change for a long time you run the risk of destroying your catalytic converter/s, it happened to me in the RX 300, basically what happens in this case is unspent fuel or combustible gases get into the catalytic converter and will at some point either not convert therefore clogging it up and create "bascially" mini-explosions eventually destoying its function, at least thats the way i understand it

btw trac always blinks when there is a CEL

Here is your parts list from rockauto.com (way cheaper than the 175$ per sensor on the RX 300)

DENSO Part # 2344209 {Universal; OXYGEN SENSOR #36531P0AA11**
Wire Length 11.77; # of Wires 4; Cylinder 1,2,3; DENSO is the O.E. Manufacturer / Oxygen Sensor; Rear
Wire Length 11.77; # of Wires 4; Cylinder 4,5,6; DENSO is the O.E. Manufacturer / Oxygen Sensor; Front
Wire Length 11.77; # of Wires 4; Cylinder 4,5,6; DENSO is the O.E. Manufacturer / Oxygen Sensor; Rear
Wire Length 11.77; # of Wires 4; Cylinder 1,2,3; Upper; DENSO is the O.E. Manufacturer / Oxygen Sensor; Front

EDIT: one more thing, clear your CEL codes by unplugging the battery for about 5 min and then go get your codes read for free at autozone or something to verify which ones you need

 

thanks how bout ma cluster not lightin up sdo u know wut that could be hope its just ckuster

 

if your cluster isnt lighting up its probably just a burnt out bulb, there are 5 bulbs total that light up the gauge cluster, 3x #194 bulbs and 2x #24 bulbs, you can get these from just about anywhere including autolumination.com, here is a DIY guide for replacing these bulbs

would one bulb result on the whole thing not working

 

i cant see how it would, however there are several different plugs that connect to the gauges so if one is loose or unplugged altogether it could have that result i would imagine

 

dam am lost this car has all lights flashin on cluster like trac brakes nd then this cluster problem i dont even know how to mess wit these machines dont know wher 2 start

 

ok lets start by listing all of your symptoms in bullet form

1.
2.
3.
4.
etc.

 

lol ok long list
1. cluster not lightin up
2. mph nd rpm not working
3. trac light on nd flasing
4. brake light on
5. when driving rear of car feels sloppy when over bumps

thanks

 

hrmmmm

ok if the cluster isnt lighting up and the needles arent working, i think you should check the plugs in the back of the cluster, if thats not the issue, im not sure

trac light on and flashing means you have a check engine light

brake light on may mean that you have a loose connector on the hand brake or the hand brake isnt releasing the whole way

driving over bumps car feels sloppy? as in how? describe more
