Lexus - RX300 :: Check Engine Light Coming On
Jan 15, 2015
I have a 2000 Lexus RX 300 with 235,000 miles. I have been having a challenge with the "check engine" light coming on. I have taken it to a reputable mechanic several times. I had the oxygen sensor replaced, and the light went out. I had an emissions inspection, and the light came back on during the test, but it still passed, and the inspection report commented that there was a communication error, but no other problems. Every time the light comes on my mechanic puts his testing equipment on and finds no problems. I am trying to sell the car, but I am concerned that any potential buyer is going to look a the high miles and the check engine light and get scared off. The car is in great condition and looks like a very well taken care of car.

We have a '99 Lexus RX300 with 174,000 miles (the engine has 130,000). The check engine light has been on for 2 years. The first mechanic found it was an O2 sensor and said that we didn't need to really do anything as long as the car was running good. So we didn't. Apparently a new code appears when running a diagnostic for the evap. sensor or vapor canister...is that right??? We had the evap sensor fixed..or so we thought and than tried to have the vapor canister worked on but the mechanic said the light came on.
Recently, the car has started lurching or losing power when it's warmed up and when it's accelerating. So, we took it to the Lexus dealership and 2 things were suggested
1) the vapor canister had been installed incorrectly and
2) sounds like the transmission is going.
So I have 2 questions, I think,
1) What is going on with the check engine light?
2) Does this sound like the transmission is going?

2000... I have a code P0171 bank 1 too lean. My question is does this exclude anything that will effect both banks? If it was MAF sensor or fuel filter would it set code and say banks 1 and 2 running too lean? In which MAF sensor ohms out correctly. I cannot view fuel trim files. I have looked for a vacuum leak with no luck. I got some cigars to try to smoke it to see if there is any vacuum leaks. Trying to narrowing what i need to checks.

I've had the JoeZ axle back installed for about two months now. I noticed that the engine light came on initially when installing but it went away on its own. I got into an accident and after the repairs were done on my car the light was gone.
It soon came back on but i expected it was because my oil change was due
Got the oil change done and the light was off. Couple days ago the light came back on.
I called the Lexus Dealer and they told me that it might be due to the Gas cap not tight enough. Gave it a few twist but light still remained on.
For the past month, I also recently noticed a mildew smell coming from the vents when i start the car but goes away. Does the mildew smell + Check engine light mean that something is wrong with the exhaust?

The VSC light came on at approximately 62000 miles. Took it too a mechanic who put it on computer, found gas cap loose, and reconnected hose under air filter however no code shows on the computer for a fix. The VSC light still remains on. Tried all the internet fixes; pulling fuse & disconnecting battery cable. The light goes out but as soon as I move the car it comes back on. Is there anything I can do to avoid a large dollar visit to the Lexus dealer since there are no driving or stopping symptoms with the car.

My father-in-law's 2001 Lexus RX300 makes squealing/whistling sound when engine is cold. Multiple serpentine belts replacements and adjustments made no difference. One mechanic said it's the bearing inside the alternator, but I find it difficult to believe. Why would bearing sound go away when it heats up? Besides, having issues with bearings inside things like alternators and such.

A few days ago my "Check VSC" warning came on along with the check engine and traction lights being on. I left my car in a parking garage for a week when I was on vacation and the lights came on once I started the car after getting back from my trip.
I have had the "Check VSC" warning before and I fixed it by replacing my gas cap. My gas cap seems fine this time around so I got my codes scanned and the only one that came up was P0300. Having this issue with the 2007 Lexus GS 350? I still feel like it's my gas cap because I bought a cheap replacement last time around.

It all started after I refueled at Mobil after a rainstorm a month ago. Could be coincidence, but right after that the car started jerking wildly and making a howling wind noise from the front. Thought it was the transmission. Brought to Lexus dealership, they told me nothing was wrong as I had low mileage on the car. There are NO Check Engine lights on the dashboard. Car "quieted down" after that, but the noise remains EXCEPT at high speed when it's quiet.
In addition to that, the jerking / misfiring continues at stops, reversing, and slower speeds on occasion only.
I tried Techron FI cleaner, but it has not made a difference. Filled up several times since then.
What's wrong?

While I am driving the car it will start to die and skip. Happens randomly. Today I was driving up a small hill and it went quits on me started lurching with check engine light coming on and off. The car will turn over and start, but only for a few seconds before dying again.
Seems to happen when the car is running for a while. Also the ABS light flashes on then off randomly while driving sometimes although It hasn't been an issue. Will be checking tomorrow to see if it starts.

Coming and going away on the next to 2nd engine start. Usually coming on after a hot run, or a hot day. Stays off for a month, then comes back. Runs fine, no symptoms, no other noticeable abnormalities.
Besides Ross Tech, VCDS, are there other softwares or devices that work for diagnostic and maintenance purposes? I have no interest in re-programming factory functions, just maintenance.

Our 2008 Prius has about 111,000 miles on it and the check engine light has been coming on and off for a day or two at a time in the past few weeks. I've seen some things online about this possibly being (1) an electrical connection issue or (2) a inverter coolant pump issue. I've been thinking about taking the car in to a local Toyota specialist to check things out, but I thought I'd check with y'all first.

I have a 2002 4 cylinder Camry, and I've been having trouble with the EVAP test completing. I've been running the EVAP test to the letter, with no success, so I figure the problem might be dependent on something else not completing.
I used to get the occasional check engine light for loose gas cap. So a few days ago I intentionally left the gas cap VERY loose (it's essentially just sitting in the filler nozzle). But I'm not getting the check engine light. I think that the gas tank pressure test may not be running, and that may be why I can't get the EVAP test to complete successfully.
Conditions: The gas level is about 1/2 full, and the ambient temperature has been around 20-35 degrees F.
I'm having a hard time searching. Most search results deal with how to resolve the loose gas cap problem. The check engine light is not burned out... it comes on briefly when I start the car!

I just bought a Hyundai Accent 08, and the check engine light has been coming on after I put gas in the car, it doesn't run poorly, it only happens after I put gas in the car. and usually after I drive it a while after. Not sure what is going on?

I am getting a check engine light about every 4 days. It is stupid suff like secondary air, or catalytic below efficency... Is there any way to prevent the light from coming on over these faults? I think it would cost me some serious money to fix everything it needs to keep the light from coming on. As you all know, once you fix one thing something else breaks.

How to reset my check engine light as well as how I can figure out what is causing the light to continue to come on. Can't keep going to the dealer to spend $ to have it turned off.

I have about 75K on my 03 1.8t on started having the check engine light coming on in the last few months. The dealers diagnosis was that I wasn't tightening the gas cap enough but I don't believe that because I do at least 3-5 clicks when I close it. I'm a bit baffled. After the last time I filled up at the gas station, I noticed the cap was loose so I've ordered another cap thinking the last one has lost its ability to seal properly...

I recently had some work done on my 2001 1.8t Passat. All new vacuum hoses & camshaft tensioner replaced by VW dealer. Check engine light is coming on and an independent shop near read out a code: Bank 1 mixture adaptation(multi): System too lean.
What does this mean??? And could this relate to these parts being replaced??? Work was done approx 2000 miles ago.

My check engine light keeps coming on. I've had a couple of mechanics look at this and they say the code indicates the transmission is going out. the transmissions does not slip or have any signs of going out.
