Lexus SC430 :: 2003 - Can Low Battery Cause Check Engine Light?
Feb 25, 2015
About month ago, the CHECK ENGINE, VSC, and VSC OFF lights came on in the dash of my '03 SC430 (~175k miles). Took it to the dealer and they read the codes; indicating a bad O2 sensor. They replaced it, and the lights went off. A few days later, the lights came back on. The lights remained ON until this past weekend.
On Sunday, i went to start the car in the morning and the thing wouldn't turn over. Turns out the battery was dead. The label indicated it was 5yrs old. So i bought a new battery. After installation, i noticed the error lights were no longer illuminated on the dash, but just figured it was due to the fact that the battery was disconnected during installation. But after driving it extensively since then, the lights have remained off.
Something else i've noticed since installing the new battery is the lack of the "rotten egg" smell from the exhaust. Before the change, i noticed a significant decrease in acceleration and the emissions smelled very bad. But for the past few days, i've noticed a dramatic increase in power and cleaner smelling emissions. Not sure if they're related...
Could the check engine lights have been the result of my battery dying? I'm not sure why they haven't come back on since the battery replacement. Nor a reason why i'm noticing improved performance and better smelling emissions.

My check engine light just turned on recently. Just hit 115K miles on my SC430 a few weeks ago. Is there a service that I'm missing? Running absolutely fine, oil change recently as well.

I have a o3 sc430 that's driving me crazy I have replaced the 02 sensor on my car three times and the cars vsc and check engine light comes back on after driving less then a mile. If I really step on the gas it'll come on faster. Where should I look for a vacuum leak? The mechanic says it could be electrical problems too...

Then about 10 minutes later check vsc shows on dash traction control light is on check engine light is on and the light next to the check engine i think it is the abs light. I havent pulled the code yet.

So I went on a little trip about 500 km away.. when i got there everything was normal.. next day while hanging with my buddies my Engine light, VSC and VSC OFF light came on.. I wasn't pushing the car or anything, driving normal and going around 120 to 135 kph on hwy there. Usually people would panic but in the past I have had cars that got these lights and usually its just a sensor.
I mean the car drives perfectly normal, i have driven it 900 km after the light, the temperature doesn't rise, there is no leaks anywhere, there is no smell, engine oil is all there, everything seems perfectly fine. I read a few threads referring to the oxygen sensor? I am thinking of getting that replaced.. how many are there that I would have to change? Also someone mentioned ABS sensor in another thread.. not sure what that has to do with the engine, i mean ABS has its own light right?

I have a 2003 SC430 with 170,000 miles on the odo. When at idle, the car shakes a little. I notice it the most when at a red light. But if I put the car in N, the shaking goes away. It happens with the most severity when in D and with my foot on the brake. I'm assuming the shake is normal for a car of this age and mileage, but i'd like to eliminate it.

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.

I have a 2000 Jetta VR6 and my Immobilizer (car & key) dash light came on, along the check engine, battery, and a few lights when tried to start my car to move it. I've been doing my research and know the problem is the communication between an RFID chip in my remote key and the key cylinder. My current remote key is old so I wonder if I need a new key. Now I do have a spare remote key (hardly used) and valet key which I could have overnighted to me.

So I went to start the car (2013 C3) and it wouldn't start. The batter was horribly dead (dim screen and would only go into POWER ON mode.) I charged the battery for like a half hour using a plug in charger using the hood terminals. When I tried to turn it on later, The only thing that came on was the check engine light (really dim) so it's not charged up enough yet obviously. The issue is now it won't turn off. That check engine light is still there. No other screens are on and the vehicle doesn't make any other noises (door ajar, etc.)

Got a new battery today but now the check engine light is on. Went to local auto parts store and was told it's the MAP sensor. I had the battery replaced 3 years prior to this and at that time the check engine light didn't turn on. Is that normal?

I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?

The mechanic I use told me how he repaired a fault with the Honda Civic hybrid battery that kept the check engine light on and indicated a code for a faulty battery. It appears that if the different cells in the battery have a voltage variance between them that is outside of the parameters set, the light will come on and stay on. The customer was told by Honda service that he needed a new battery, but the car was out of the warraqnty period.
The mechanic theorized that he could remedy this if he drained the battery down and recharged it. After two cycles, the check engine light went off. I wonder if this would work for other hybrid owners?

2nd battery in 2010 Sonata 4-cyl died on my wife last night. Got a new battery today and put it in. (Couldn't move car even to push as there wasn't enough juice left to get transmission out of Park). Started right up after battery replacement and ran engine at idle for probably a half hour. Engine seemed to run a little funny. Lost RPM's and sounded like it might die a couple of times, but it stayed running. Now the dreaded check engine light is on. I've had a couple of stop-starts since it began, so I'm not sure it's going to go away. Car seems to be running fine now. Is there a connection between the battery going dead (so dead I lost radio presets and trip odometer readings) and something fouling up the check engine system?

2009 Sonata 4 cyl with 40,000 miles.
My car was slow to start last night. This morning took it to Autozone and they checked the battery, which was bad. Got the new battery installed and drove about a mile then turned off engine. Upon restarting engine, Check Engine Light came on.
The timing is such that it seems the CEL is because of the battery. How to handle? My car has otherwise run perfectly in its first 40,000 miles of life. Only other relevant detail is that the presets on my radio kept resetting, I figured this may be because of low battery power.

I have a 07 Camry XLE. My previous battery started dying on me so I changed to an Optima Yellowtop battery. Next day the check engine light came on, and sometimes while idle the car starts stalling, it never turns off though just that the RPM goes really low and the acceleration is really slow and it feels like the car is having trouble accelerating. Today it happened again but I was over 60MPH and hitting the gas pedal and it seemed to stop accelerating a few times.

I have a small problem with my 2011 Camry base model manual transmission. I replaced my rear view mirror and installed the EC homelink with compass rear view mirror as the replacement. I followed the instructions and it works fine but after connecting the battery again and turning the car on my check engine light stays on. I had the same problem when I installed my HID head light kit and I disconnected the battery and apparently it reseted the computer because the check engine light turned off, but I tried to disconnect and reconnect the battery twice now after installing the mirror and my check engine light is still on. How to reset it?

My check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)

I only drive my car once a month or so to visit family. A few years ago my 12v Battery stopped working in my car. I assume age and just moving my car from one side to the other every morning contributed to this. I got the battery replaced at my local Toyota dealership in Jan 2012.
In early March of this year my 12v battery died again. I jump started my car every morning (with a portable battery pack) until I was ready to drive it a distance a few weeks later. I got about 2 miles and then my check engine light came on as well as my Hybrid System Warning Light.

I went out in the 9 degree temp this morning to start my car and take off for work. I sat down and hit the power button and some console lights came on. The gear lights were blinking with a square light around each letter (P, D, R, B...) and the pips on the fuel gauge were blinking, beeping during each blink. Also, the green light on the power button was blinking and the little light showing that the key was not in the car was also on but the key was beside me. I turned it off to try it again.
Before I turned it back on, I inserted the key in the slot and hit the power button again and just the Check Engine light came on and everything else was black. There was a slow tempo click-click-click-click... sound coming from under the hood and the Check Engine light was just sitting there. I tried to turn the car off but the power button was not doing anything. All I could do is let the Check Engine light stay on and the click-click-click-click... sound chirp away. I went back out in a couple hours and the battery was dead.
Just seeing if that might mean something specific before I go drop about $200 on a new 12v battery later today.
