C1241 is low voltage warning and C1223 is an ABS control system malfunction.
Are or could these be related? Where should I start to troubleshoot the issue?
I checked the air in the tires on my 2008 350 ES with an outside temperature of around 40 degrees. Pressure gage read 25 lbs. I decided to add pressure to bring up to 30 lbs. Subsequently while driving, the Trac & VCS System malfunction warning symbol came on (the picture of a car with wavy lines behind the tires). Of course, the warning symbol of a red triangle with an exclamation symbol in the middle as well as a check engine light also came on.
I figured that the problem was that the combination of cold weather (for Houston) and the added air pressure resulted in the system interpretation of an increased skid or lack of control situation. So I let some air out to where the pressure in each tire is 27 lbs. Then I drove it 5 miles or so at speeds up to 50 mph. Made no difference. Warning symbols still there.
Need to replace Seatbelt assembly on a 2004 GX 470 driver's side?
Mine reads sometimes, but other times I get the airbag warning light, so I need to replace it.
I have a 130K+ 2002 SC430 in which I recently started to smell gas in the cabin when air vents were set to pull air from outside. Within two weeks, I got the check engine light with two codes, P0440 and P0446, which mean "Evap Emission Control System Malfunction".
In doing some research the check light light could be everything from a gas cap which is not tighened properly, to a bad "charcoal canister " (whatever exactly that is), to a cracked or disconnected "Evap Hose". The only other SC430 related thread I could find on this topic is [URL] ....
If it factors in, I only use 93 octane gas. Interestingly enough, the check engine light came on within 30 seconds of me using the window washer to clean the windshield (at highway speeds), likely a coincidence.
I'm the owner of GX 470 2006 85 k miles, facing a problem of height control failure. The problem started some few months ago while starting the car. I there was a noise behind on the height compressor. Took it to my mechanical and the noise disappeared because the compressor wasn't well fixed to the body. Since then i'm not able to adjust the height of the car. The car remains at the height low level and jumping dangerously each time i drive it inside a hole. Decided to go back to the mechanical the following code error appeared during the diagnosis: P1445. How can this code be related to the height control system when we know that this code is related to the secondary air injection system switching valve?
I decided to change the 2 height sensors located on the R and L rear side of the vehicule and the VSV locate in the engine. The problem remains. Now the dashboard keeps the green light at N and the button to raise and low the height of the car is not responding. More the mechanic can't anymore obtain the errors code from his diagnosis device.
I was recently in a rear-end crash. The body-shop presumably disconnected the battery, fixed the rear door, and then re-connected the battery.
Now, however, the Navigation screen just flickers.
If I press Info, Audio, or Climate, the screen is just fine
If I press Menu, Dest or Display it flickers.
(Curiously, if I press Info, Audio, or Climate AND THEN press Display, the DISPLAY is fine)
Took it to the dealer, who said it was a coincidental to the body-shop repair.
I own a 2002 SC430 with 20,200 miles on it which I purchased new. The other day the check engine light came on. I checked it with the code reader and got the following 2 codes. P0300 (random multiple misfired detected) and C1201 (engine control system malfunction). The car ran great before, now running real ruff and when you drive it has less power.
View 9 RepliesI bought a 2003 GX470 a couple of months ago and love it. It was a good upgrade from the 98 Land Cruiser I had a couple of years back and much better than my recent X5. Even though it runs great right now, I have one issue bugging me.
The Navigation unit hasn't ever really worked. Actually, it works, but since I bought it has used the secondary system which calculates location based off direction and speed which is only accurate if driving 50 yards or less - even after calibration
I found out how to get into the secret menu and looked through the settings. When I go to the screen which shows connected satellites, it says "Ensure nothing is blocking gps reception." I've tried a couple of resets, but nothing seems to work. I looked up where the antenna is to see if the connections is loose, but the only reference I found said it was on the rear glass. Unless integrated into something, I don't think it is, though.
The system still runs a factory 2003 disc for maps which is Gen 3. I tried a used 2007 map disc which upgraded the system, but didn't work. It gave disc errors so had to go back to the 2003 one. I haven't had a GPS signal since the day I bought it.
Rear heating system in my Lexus GX470 only blows cold air, what could be the problem. Front heater works fine.

View 5 RepliesMy wife's 04 GX deflates sometimes when we park it, you can clearly hear a loud "whooshing" noise occasionally when we park it in our garage. The rear then goes to the lowest possible setting, it looks odd laying that low. Because it's not my car, I don't know if it always did that, but it seems "new" to me.
The deflation sound is coming from the rear mounted compressor on the rear driver side, I went under the car to investigate. It also appears that the air bags themselves aren't leaking, I raised the car to the highest setting, and it stayed there without the compressor kicking on or any leaking noise.
My guess is maybe the sensors need to be replaced, the thing is, I don't want to "shotgun" parts at a problem and spend $500 or so dollars on new sensors to experiment. How do I know the rear is behaving correctly?
Alternator on my 2006 GX failed, caused battery to discharge and vehicle stopped. Alternator was replaced, battery (was new) is testing fine. All electronics and indicator lights normal except Nav system. Display reads insert proper disc. I have ejected and reloaded disc multiple times, no change. Disc is OEM, one release back.

View 14 RepliesI recently acquired a 2003 Dodge Neon and have also aquired a problem with the automatic transmission.The check engine light was on so I read the codes and they are noted below
P0700 Transmission Control System Malfunction
P0755 Shift Solenoid B Malfunction
Based upon some very basic research, I checked into replacing the Transmission Control solenoid.It sounded like this is a pretty common problem for this transmission, so hopefully this would fix the problem.
I was able to get the old one pulled off without to much trouble, but prir to installing the new one I was wondering if there would be a way to test the old one to verify that it was actually bad. I would prefer to not install the new $150 part only to find out that this was not the problem. (and then I could not return it once it had been installed) Maybe some low air pressure on the ports and verify that the ports / flow changes if 12 VDC is applied to the right pins?
A little more information in regards to the "failure" mode. The transmission appears to act the same no matter if it is placed in 1,3 or D. (reverse works fine) I would have expected that it would limit out with the motor taching up pretty high at about 20 MPH in 1(low). It goes down the road fine up to about 55 mph and then the engine starts taching up.
I also tried to reset the error codes with my "craftsman" code reader and it would not do it. I seem to recall seeing something about needing to reset codes before the new solenoid would work. Will pulling the battery for an hour clear the code? Do I need to clear the code?
On my way home from work tonight, the master warning light and the check engine (malfunction indicator lamp) appeared on the dashboard, and the hybrid system warning light has popped up on the multi-informational display.
View 11 RepliesThe first is a trans control system malfunction and the 2nd code(0740) is tcc circuit malfunction- but what exactly do these codes mean? and the o2 sensor needs to be replaced, it said bank 1 sensor 1- does that mean the one BEFORE the catalytic converter?
View 4 RepliesBack in March I started a thread regarding my 04 Santa Fe 3.5 which would not start after a spark plug change.
After a ton of research, & a smoke test on the intake I came to the conclusion that there was an issue with the throttle sensor as I unknowingly opened it when I was removing the intake to get to the last bolts behind the manifold. Shortly after my post, I decided to bite the bullet & buy a junkyard TB out of another Santa Fe 3.5.
After installing the new TB, the car now starts but runs extremely rich. I am now getting the code p2135 for Electronic Throttle Control System Malfunction.
Luckily up until this point I haven't needed the Santa Fe as it is mainly a winter vehicle. However, winter is quickly approaching & I would like to have her running before the snow starts to fly.
I have a 2006 RX400h. On 3 occasions I've been stranded. The car won't start and I get an error/message Shift to P when Starting. However I am in Park. It's coupled with a Check VSC System warning. Service department says I have just drained the accessory battery, however nothing is being used other than standard equip such as lights, dash etc. I've had all batteries changed in the car over the 4 years I've owned it. Is this usual?
View 14 RepliesI am getting to check engine codes and I can't figure out what is causing them, one is P1296 cooling system malfunction, the other is P1654 Check DTC Memory of control panel ECU, any clues as to why I'm getting these, I did have a bad thermostat i changed that and it's still on, I also used the new prestone antifreeze for all makes and models, cause I am about 200 miles away from a dealership for g12.
View 6 RepliesAfter not driving the car for over a week, the battery was dead and I discovered that I had not fully shut the trunk. I hooked up a charger/maintainer with the battery still installed in the car and it has been on for 48+ hours and it still shows as charging. I have several of the chargers and use them on other cars/motorcycles where they work as expected. I've never had one take this long to indicate charged.
I'm sure others are using maintainers and wondering if it is normal that the charger does not indicate full charge. Voltage with charger running is ~14.7 and ~13.7 unhooked. I believe it is a 4a charger.
What is normal voltage when fully charged and what is minimum voltage to crank starter?
Should have measured the voltage before hooking up the charger to know low it was......
I'm not too knowledgeable about wiring and electrical systems. I'm getting a P1451 code (EVAP Control System Canister Vent Solenoid Circuit Malfunction) on my 99 4.2. I've read that it could be a bad solenoid, bad wiring, or a blown fuse. So far I've;
- checked (and changed) the related fuse
- checked the wiring for damage at the connector
- checked voltage at the connector (12 volts)
- checked the resistance at the solenoid (around 60 ohms)
- actuated the solenoid with a 9V battery (can hear it opening and closing)
I haven't had a chance to check the wiring all the way back up the frame to yet, but I noticed that the ground at the trailer wiring harness has broken off the frame. Would this potentially cause a fault in the upstream wiring? I'm going to slap a new connector on and bolt it back down anyway, but as it's Labour (Labor) Day I'll have to wait for the stores to be open tomorrow.
