C1201 lexus is250

Hi guys, recently i got an issue with my ISd. It stated that the ABS malfunction and when i googled the code it stated the LF speed sensor malfunction. Anyone have ever experienced this sort of problems? From what you have described it would point to a faulty left front ABS sensor which is mounted on the hub.

Being positioned where they are they are subjected to dirt and water and damage so 1st thing to check is the wiring to it including the plug and socket, clean all the dirt from around it and make sure it is all secure.

There is also a toothed ring on the hub which the sensor uses to determine if the wheel is turning or has locked up, make sure this is also clean and none of the teeth are damaged.

The link below explains the basics and may help you locate the components mentioned although on the IS the layout will be slightly different. Thanx Steve, will try to check and clean up the sensor. Will keep you posted. I'd say so You can post now and register later. If you have an account, sign in now to post with your account. Paste as plain text instead. Only 75 emoji are allowed.

Posted March 24, I 14 minutes ago, PCM said:.We just got an oil change and our tires rotated a couple of weeks ago. We have to drive long distance this weekend so I want to know if it is safe to drive with those lights on and if there was any way to stop the lights from coming on.

I wasn't sure if it was an easy fix or something we did wrong starting up the car or turning off the car. If not then any ideas of what is causing them to come on? Also, if we do have to take it into the shop any estimation on how long it would take to fix and how much it might cost? Any suggestions help! It's a program that helps regulate your shocks, and brakes during emergency maneuvers.

It comes on when the computer detects some kind of problem. The check engine light coming on makes sense also. Yes, it's perfectly safe to drive with the lights on, provided the check engine light isn't something more serious to your actual engine. You can take it to the dealer or almost any Auto Parts store and have them check the Codes that it's throwing. That will tell you what the problem is and if you can be driving it or not.

Until you know what the Computer is saying it's impossible to speculate on what the cause could be. Finding out what the codes are is easy and quick. Getting it fixed could be a whole different story. Could be as simple and quick as changing a shock, to more diagnostic work.

Get it in, and have the codes checked as soon as you can and then depending on that go from there. The VSC system that controls your brakes, only distributes a certain amount of force to the rear wheels, and modulates it. So to anyone who thinks it's not ok to drive with a VSC light on obviously knows nothing about Cars. Because it is perfectly safe to drive with it on. You just have to be smarter than the Car you are driving.

IS and same warning lights happend me, but the car was driving as normal?! I mentioned ot my mechanic that i was doing this also, just in case! How long the problem if it even is one stays away for, i dont know! As suggested in one of the previous posts, I drove the car for 2 milesturn the car off and back on, but the error lights did not go away. And that the car is still OK to drive but it warns that there will be no ABS, no auto engine braking, no skid control, etc. That left the engine error light unexplained.

The manual did not show that the engine would also come on with a VSC error. Given the engine error code, I gingerly drove it to a nearby Autozone for a free computer check. Unfortunately the Autozone computer could not read anything related to VSC. But it was able to explain the engine error light. It seems that the 2nd stage oxygen sensor was the cause.In this guide, you will learn about Lexus check engine light, symptoms, common problems and how to read the codes via the OBD-II port. This could be something as simple as a loose gas cap or a more severe problem like a bad VVT solenoidbad spark plugs, catalytic converter or even transmission issues.

The fault code provides clues as to why your Lexus check engine light is on. You also might notice that the car is misfiring or overheating. However, sometimes there are no symptoms at all. If your Lexus seems to be running fine but the check engine light still comes on, don't brush it off.

Make sure you get it checked as soon as possible. When your Lexus check engine light comes on, we recommend checking a few basic items before you continue your journey. Do not continue to drive if the check engine light is flashing. Fault codes will display on the OBD2 scanner such as P for example. Write down all the codes and do further research to understand what they mean and learn about possible causes. After the problem has been resolved you'll need to reset Lexus checked engine light by going to Clear Codes menu.

While they often give you a very good idea of what it is wrong, we recommend having a professional car mechanic properly diagnose the check engine light before you replace any parts.

A spark plug that no longer fires is one of the most common problems that triggers the check engine light on Lexus vehicles. Many owners don't realize that spark plugs are wear and tear items and need to be replaced according to the recommendation in the owners manual.

Typicallymiles. On older Lexus vehicles that were equipped with copper spark plugs, you had to change them every 30, miles. Newer models are equipped with Platinum or Iridium spark plugs that can last overmiles. Ignition coils are in charge of generating electricity for the spark plugs. Older Lexuses only have one ignition pack while newer cars have one ignition coil per cylinder.

If something is wrong with the ignition coils it will most certainly trigger the check engine light along with codes such as P, P, P, P, P Remember, if you have a diesel Lexus such as LX V8 diesel, it doesn't have ignition coils so this won't be the problem. Most Lexus engines have variable intake manifolds, which are a bit more complicated. This added complexity makes them more prone to intake leaks, resulting in a lean running engine. You will usually experience symptoms such as rough idle, lack of power or hesitation on accelerations.

Such behavior can also be caused by a dirty MAF sensor, giving false air quantity readings. Codes: P and P The cams will either advance or retarded the timing depending on engine speed and load. If you have VVT problems you may get fault codes such as P, P, P in addition engine will idle rough and feel underpowered.

The gas cap is a key part of your car,s fuel delivery system, so if it,s not tightened properly it could lead to gasoline fuels leaving the tank. If the light turns on immediately after filling up your tank, this is a good place to check first.

One that is particularly common on Lexus vehicles is the converter under-heating. They found that the converter seemed to be working fine but the sensor didn't think it was.

So that's something specific to watch out for. Although stored codes will usually point to a catalytic converter low efficiency, it is easily possible that you have a faulty downstream o2 sensor.

Make sure to rule this out before changing much more expensive catalytic converter. Oxygen sensor O2 may fail triggering the check engine light to come on. A common fault code triggered by a bad Lexus oxygen sensor is P, P, P related to AF Sensor which means the circuit for the heater element of the O2 sensor is defective. To fix this problem, you will need to replace the oxygen sensor.I know there have been many posts on the "check VSC" warning light.

But most of them are older and I am hoping I can get some more current insight I started and stopped my IS the other day and noticed a shudder. Upon starting it up the next day the car almost stalled and the check VSC, traction control and Engine lights came on.

C1201 - Engine Control System Malfunction

It has been running fine since but the lights still come on. I am curious if there are any recalls given all the discussion on this and what might be causing it.

Or more importantly if there are any quick fixes before I shell out to a dealer. It seems pretty hit and miss but any insight would be greatly appreciated.

Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor. What does this mean? The auto repair labor rates vary widely across the country, and even within the same city. It measures the intake flow rate by measuring a part of the entire intake flow. The temperature of the hot film is controlled by the ECM a certain amount.

The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases.

The ECM detects the air flow by means of this current change. Get Access to Factory Service Manuals. Related Information. Repair Importance Level: 3. Why is the Engine Light ON?When you check Lexus Is car engine light came on code C the reason should be. So you should chech it on our car models.
