I got 2002 SC430 with 59,000 Miles, all of the sudden my car doesn't have any acceleration at all. When I press gas paddle it doesn't do anything, but engine stay on. I couldn't get any error codes since I changed batteries to make sure if it wasn't the battery..
View 4 RepliesOver the last few months I was having a problem with my 2002 SC430 with 130,000 miles having random hiccups and engine hitches during acceleration and even at random times while on the highway or around town. My average 10 minute trip around town would have at least 10 hiccups, all random and during no specific style of driving. No one wants a stuttering engine!
After reading some of the threads here there were several options...
1. Do a system reset by using only the key turned on and pressing on the gas pedal for thirty seconds. While optimistic, this didn't solve the problem...
2. Many threads suggested that it may be my TPS (throttle position sensor) so I started shopping around for a sensor to install myself. They run for about $75 online and are a pretty easy install..but I wanted an official opinion so I went into my local lexus dealership to ask them if this was the best course of action...
The solution: Apparently, the 430 engine is a notorious carbon producing engine so, as my local lexus mechanic explained, this carbon can build up in the throttle body, affecting how the mass air flow sensor (MAFS) is read. My mechanic recommended having a FUEL INJECTION SERVICE. This service cleans the fuel deposits in fuel injectors and carbon build-up in cylinder heads and in the throttle body plating.
Started up the SC 430 (2002) and a clicking noise is coming from the engine. After engine is warmed up noise settles down. Have 71212 miles
View 10 RepliesThe shocks (or whatever) that keep the trunk open have gone bad. Of course it happened a month after my warranty expired. They look easy to replace. Where to get them, cost, and how to install? I don't like going to my Lexus dealer. They make me feel like a criminal for not changing my oil every 5k, changing my own filters, etc, etc. etc.
View 14 RepliesGot an '02 here. This noise started to appear recently. When I turn the key to put electricity on (without starting the car), I hear this electric motor-like sound, similar to power window sound, coming thru the dash area, and it can also be heard outside the car coming from somewhere in or near the engine compartment or in front of the dash/windshield area. Could this be one of the servo that operates the AC vents? or its something else?

The engine is running shaky. If you just hold your hand on the steering wheel you can feel the engine shaking.
The car has brand new sparkplugs. What could the problem be?
My front drivers side pillar is flapping around and won't stay in the set position. It seems to be the washer that the one of the clips goes into (at the very bottom of the pillar) has corroded.
So firstly I am trying to take it off - but after reading the removal of windscreen instructions I see:
21. REMOVE FRONT BODY PILLAR OUTER RH
a) Remove the nut.
I can't see a nut and if it's under the pillar how do I access it?
And then
34: INSTALL FRONT BODY PILLAR OUTER RH
a) Exchange the clip with a new one
What clip is this referring to and what is the part number.
As I have experienced hesitation on acceleration from a stop, I found a TSB # L-SB-0154-10, that addresses this condition for the 2010 SC430. It was issued in 12/1/2010. I am not sure if it would apply to any other years. The TSB entails re-flashing he PCM with updated software.

View 14 RepliesI have 2002 SC430 with an annoying vibration through the seat/chassis at 60mph but she's smooth at 55 and slower and at 65+ mph ? Things I have tried so far ...
wheel balance
wheel alignment
2 rims rerolled that were out of round
bushes and suspension all checked
moved wheel positions front to back etc
Thinking now maybe driveshaft or uni joints ? or new tires but that's an expensive exercise !!
My brake light and ABS lights appeared today on my '02 SC430. What this might mean and the solution?

View 6 RepliesMy check engine light came on.. so I took it to express tires.. And they said that they need to replace my vacuum hoses cause it busted ... well when I saw the guy used the obd checker thing.. after checking the codes.. i saw that when u turned on the engine.. the vsc on and vcs off lights came on..
So I figured after he fixed the problem.. it will go off.. well after he got done.. fixing the problem.. I drove away.. after bout like 2min.. i had to turn around cause the vsc on and vsc off came on.. and I told the guy to check.. And he used his checker.. and there was no problem.. and the "check engine" light is not on anymore.. just the vsc on and vsc off!!
Could the checker.. messed it up??? the vsc off button.. only works when the key is turned on.. " not when the engine started but right before it.. when the power comes on" so the button is working correctly.. it just comes on.. when i start driving the car...
And no they did not check my tire pressure or do anything to the tires or the wheels.. it just turned on.. when he inserted the obd thing to check..
And yes I read the [URL] .....
Is it dangerous to be driving with the vsc and vsc off light on??
I recently got into my 2002 SC430 and could not shift the car out of park. In addition, another symptom was that when I pressed the brake pedal, my rear brake lights would either come on momentarily and then turn off (looked like a strobe-light effect), OR the rear brake lights would not come on at all (the taillights, however, continued to function).
The only way to get around this issue was to use the manual override (by taking out the little plastic tab on the shifter and using a screw driver to press the hidden button, which would momentarily override and let me shift).
After much research, I found out that my Brake Switch/Sensor was failing (this is what tells the car's computer that you're pressing the brake pedal, and thus allowing you to shift out of Park). Unfortunately, I don't have the model number handy.
My non-Lexus mechanic charged me $100 (parts and labor) to replace the Brake Switch/Sensor. I'm not sure how much the actual part cost, but it couldn't have been much. It's a very scary feeling when you need to drive somewhere quick and you cannot shift out of Park.
I had to replace the ECU on my 2002 sc430. Although the original ECU was malfunctioningthe car started and was drivable (but the speedometer and odometer did not work, nor did the power steering). Following installing a used ECU, the car will now not start. I reset the ECU following the directions posted by others in this forum (both the gas pedal method and removing the fuses), but that has not fixed the problem. Do I need to have the dealer sync the key to the new ECU?
View 6 RepliesI have a 2002 SC 430 with 68,000 miles on it. Having problems with the transmission? Today, I could not go forward in any gear...could go in reverse. I turned off the ignition and re-started the engine, then the car worked fine.
Tonight I went out and the car was fine. However, later had the same problem.
I just purchased a 2002 sc430 and the steering was nice and solid. It needed new tires, so I purchased them at tire kingdom. they told me I needed a steering flush (lexus did as well at my oil change) so I to0ld them to do the flush. When I got my car back, the steering was so flaty, I have to keep my hand on the wheel all the time, they gave me an upgraded tire, to the falken, felt a little smoother but still floaty. brought it to lexus, they said it was the tires. the rear needed 255 and front 245. they upgraded the tires again and I still have the floating steering wheel.
View 3 RepliesThis week I began experiencing operational problems with the mark levinson stereo and I'm looking for a logical next step to resolve
1). I cannot adjust the volume either from the volume **** or from the steering wheel. I have volume I just cannot adjust it.
2). I cannot eject any of the CDs. I can play them.
3). Tapping the tuner **** should take you into stereo setup where you adjust bass, tremble, fade etc. when I tap it there is no response.
I can tune the radio fine. I can play the CDs fine. It does not appear to be fuse related
I called a car stereo guy who rebuilt my dried out speakers today and he suggested disconnecting the negative battery connection and touching the positive connection and that might reset it. That sounds scary to me and I do not want to harm any other components (or me!) by trying this. Any logical next step to resolving??
I am the original owner and all these symptoms happened at once and started after car sat in garage for a week. It has a new battery installed last year and shows no sign of a weak battery

I'm having some trouble regulating the cabin temp in my 2002 SC430. It's cold outside here in Atlanta (in the 30's in the morning) and for some reason even when I have the temp set on 66 (not in auto mode) the cabin gets really hot! If I drop it to 65 the AC comes on. It's just weird.
Not sure where the temp sensor is located (will check the manual for that) but having a problem regulating the cabin temp. If put it the auto mode -- it ramps the fan up to high and cooks us all inside the car.
