Lexus RX 2004-09 :: RX330 TPMS Warning Light Came On / Water Temperature Gauge Dropped To Zero
Dec 12, 2015
My 2004 RX330 which has gone many years without a problem suddenly has instrument panel gremlins.
I started the car a couple of days ago (it had rained during the day), and the airbag light did not turn off. Then the TPMS warning light came on, the water temperature gauge dropped to zero. The AC controls stopped responding. Since I needed to get home, and the car seemed otherwise fine, I drove home, after a few minutes the transmission "D" drive light went blank and the instrument back-light went to full brightness.
A few minutes later, all the warning lights went off and the back-light went back to normal. The AC controls still seemed to be off. A few minutes later the airbag warning light came back on, followed by the TPMS light and the back-light went to full brightness again. This cycle kept happening all the way home.
The next morning, hoping the problem had been some errant water getting into something, I started the car, opened the driver's door to get something and got back into the car, closing the door. The light showing the door was open stayed on. I put the car into reverse, the doors did not automatically lock as they usually do. I turned off the engine and restarted it, most of the other lights were off, the doors would lock; airbag & TPMS light came back on.
It has stayed that way, except I also get the A/T temperature warning light coming on periodically, and after some cycle it goes off.
I borrowed a car code reader, it does not seem to show any error codes. In reading some other postings it has been suggested that the Brake light switch is the cause, but the brake lights come on/off without any problem.

I have a 2004 RX330 that all of a sudden had the SRS warning light come on as well as the passenger airbag OFF light being constantly lit up even when someone is sitting in the passenger seat. I put the SRS system in diagnostics mode with a jumper clip to determine I am receiving a DTC of 23. Documentation I have found for this online states for Lexus it is a occupancy classification system issue which I know means it's something on the passenger side.
This seems like it would be related to the occupant seat sensor itself which I am first of all wondering if it is bypassed like the BMW guys have done on their cars when this issue happens.
Secondly, I'm wondering with this specific code of 23 could it be anything other than the seat/weight sensor? My passenger seat belt has tons of slack and doesn't retract as it should so I'm thinking maybe pre-tensioner sensor but not sure because it also seems to stick when trying to unbuckle it as well which leads me to believe it could be the fastener sensor.
I feel very unsafe having any passengers in the vehicle right now and the car is well beyond its warranty of course so bringing it in to the dealer is really a last resort option for me since I know at minimum they'll charge $1000 for SRS wiring issues based on what I've read.

About four days ago my TPMS warning light started blinking. Same tires and sensors have been on there for quite some time. The service book says to take it to the dealer, but I instead stopped by Discount Tire (where I purchased the tires) to see if they could look and figure out which sensor was acting up.
When he ran his sensor, none of my four sensors showed up as broadcasting at all! Now I know that all four of my sensors did not just randomly go out at the same time.

So I was running stock Lexus 17' rims on my 2008 c350 RWD. The time came to replace the tires and I thought- instead of shelling out hundreds of dollars, why not use my brother's set for free (his stock 17' rims from his 2006 GS300 RWD were just lying in the garage taking up space). They were also 17's. So, I swapped all 4 out, stock rims included. Drove around for a bit and noticed the TPMS warning light came on.
Not the low pressure light, but the actual warning light. This happens every day. The car is fine driving the first 15-20 miles but after that, the light always eventually goes on..then it's magically reset when I start the car the next day.

TPMs warning light on. I was wondering is the reason the TPMs warning light is on because I don't currently have a spare tire in the trunk i have the tire i mean but no wheel. and the sensor is just sitting in my glove box until the new wheel comes in.

Thursday driving home from work, the thing started dinging and all sorts of lights started flashing at me. I looked in the manual and (finally) found that it is the TPMS. The orange light on the left side blinks for 1 minute and then stays on steady. I also see "Check System" in the display under the speedometer and there is a red light with an explanation point (!) on the right side. Checked all tire pressure. All were at 30 PSI. Checked spare, it was good. Manual says if it blinks and stays steady, contact your dealer. Called...they can't look at it until Feb. 12. I drive 40 miles a day on average. Not a lot, but by 2/12 that is several hundred miles. what could be wrong and if i should still be driving this car?

When taking our 2007 RX out of say a 72 degree garage to say a 90 degree day, it takes at least 10 minutes for the outside temp gauge to finally creep up to the ambient temperature. The gauge feels very sluggish at all other times.

Hard to fix? Only happens when going under 5 mph either in slow traffic or slowing down to park in parking spot or just stopping the car. Doesn't happen at high speeds. It's like I'm driving on snow or ice or wet pavement but there is dry pavement. Brake pads and rotors were cleaned with no success. Guessing that a sensor is dirty or broken or such.

With the temps at a all time low in the U.S. this week, my TPMS warning light has come on in my 2012 RX350. It will stay very cold for most of the week, so is it ok to drive with my warning light on.
I don't want to check my psi in the tires with a tire gauge because I was told a valve stem can freeze open in extreme cold letting the tire to go completely flat.

Just a little PSA, if your TPMS light shows up, and all the tires (including the spare) are at the proper psi, check the button below the glove box. As long as the warning light is solid, its likely someone pushed the button. I almost paid $120 in diagnostic fee and $150 for a new sensor at the dealer because for some reason, no one knew about this button, or didn't want to tell me.

2004 Lexus rx 330 with 53000 miles, I took it to the dealer for 50,000 mile service when he requested me to change water pipe for coolant because he found heavy coolant residue under the water pump. My question is do I need to change timing belt also right now. when I called the mechanics some of them recommending me to do the timing belt also.

I have a Lexus RX 330 2004 which I recently made some changes to the front end suspension, since then, my car beeps whether i turn or I drive even in straight line beyond 40MPH. The beep comes along with a light in dash with an icon of the car with curves.
I have read something referring to a zero calibration. Which pins to short to perform the calibration? Since I don't have the lexus diagnostic tools, I heard its the CG and TS pins but What pin numbers are the on my 2004 AWD RX 330?

where best place to start looking for what's causing p0442 code on my 2005 rx330? and its not the gas cap... also have a "c" code identified for the VSC light, states that its wheel speed sensor. evidently wrote the wrong code down, i had it listed as a c1290 but in looking them up i couldn't find that one.

The passenger side HID bulb of my 2005 RX330 need to be replaced, how to? Also there is condensed water in the assembly. I am going to replace it later. Where are other screws beside two on the top?

I JUST got my brand new 2011 gti this wednesday, which I am obsessed with. When I was driving around earlier yesterday however, the temperature gauge started to go up and into the warning zone. a message on the dashboard then sed "check engine coolant see manual".
So i did, and according to the manual everything should be running perfectly fine. So i pulled over till the engine cooled down to normal, then after about a mile it happened again, and it kept overheating every mile. I got the car towed by vw to a dealership nearby, but they're closed on sundays so i have to wait till tomorrow.

My wife's RX is really starting to give me a headache. The first problem I'm having with this car is detonation. The car starts pinging at part/ light throttle once the engine is fully warmed up. The is no CEL or codes pending. After scanning the car it seems that fueling is right where it should be and nothing else seems out of order. The pinging stops when you hit the gas harder. So far the only way to rid the car of this problem is to fill with 93 octane and that gets expensive with a daily driver. Shouldn't the knock sensors be handling this? Is there a way to test them?
The second problem I have is the heat won't turn off. Hot air always comes out at what seems to be low fan. I can move the area it comes from ( dash vent, floor etc) but I can't turn it off. With the fan set to off and no settings chosen I still get heat.
The car currently has 78k miles on it

Just about every trip i take my temp gauge pegs and dinger goes off and check gauges lights up in the message center. It eventually will go back to normal or if i shut key off and restart truck it goes to normal. im guessing it is the temperature sensor for the gauge but not sure?? If it is, where is the gauge sensor located?

I was driving and noticed that my temperature gauge went close to the warning zone so I blasted the heat and it went back down. When the car cooled I popped the hood and noticed that the coolant reservoir was pretty close to full but I couldn't see any coolant in the radiator. I filled the radiator with water for now but it looks like it gone again. I cannot spot any actual cracks or leaks on the hoses but I did spot a puddle of coolant in the groves on top of the transmission. The closest hose I can spot next to the puddle is the lower radiator hose but I really do not know too much about cars. I also noticed a hissing sound today coming from the radiator cap, which I am going to replace. Where the leak could be which is causing the puddle on top of the tranny?

I had new tires put on last week. Two days after the TPMS light came on steady. All tires including the spare had 32 psi in them. That's what is listed on the door sill. I added a little more to 35 psi. Same result. I finally bumped it up to 40 psi. 4 shy of the max. It's been 2 days and no change. Since it's was a couple of days after the change is this a coincidence or is there some reset. I hate to disable it since its my wife's car. Also checked the switch under the dash.

I did the blue wire cut-mod 20 minutes ago. I had a consistent blinking TPMS light. I cut the correct, blue, wire and grounded to a stud behind the kick panel. The light is now steadily lit. Was I supposed to disconnect the battery first?
