SOURCE: 2004 Camry XLE fuel gauge problem

Check online in other forums of this particular issue. Others may have had the same issue and have found answers through other sites online. Sound like a bad sending unit "fuel gauge sensor". Unfortunatly, it may be a requirement to remove the fuel tank to gain access to this fuel sensor. If you dont have the means to repair this problem you can always keep track by the mileage that you put on your vehicles tripometer. I know thats a pain but it wont cost you any money until you choose to have the repair done.Estimate your mpg's and the size of your fuel tank by the gallons, and multiply the two. Be sure to keep track and have enough fuel not to run out! Its always better to keep half a tank than an eighth of a tank!

SOURCE: Warning lights on a 2006 toyota rav 4 32,000 miles

I had the same problem. A computer check showed that the emission system was having difficulty. The catalytic converter had to be replaced. The car had under 80,000 miles on it so it was covered by a warranty (State law? Federal law?).
My battery was also dead. That was replaced free too. It had a 7 year warranty.
I do NOT purchase extended warranties.

SOURCE: Code P0174 05 Corolla

I don't show any po174 for an 05 corolla. But I do show a po741, if thats the code you're getting.
It means theres a problem with the torque converter
clutch system. It could be the tcc solenoid. Either way, it's related to what you just had done.
Good luck.

Good Day qits81, if your vehicle does not do anything funny while running it is nothing to worry about. Under normal operating conditions the engine control unit runs an automatic system diagnosis program to ensure that the engine runs at an optimum. As soon as the engine control unit received "feedback" from the sensors and all is o.k the light switches off. If there is a problem with one or more of the systems the check engine light will stay on to warn the operator that they need to have it checked out.

Aygo dashboard signs

that little orange light is the check engine warning light.
that means there could be something significantly wrong
the light is turned on by the computer in the car, the computer was told by one or more of the electronic sensors that something is not correctly working.
Take you car in a service repair company or the dealer and have the "engine check light diagnosed" they will tell you afterward what could be not working correctly.

Intermittant engine management light comes on after approx 250 miles when checked at dealers no fault showing but lambda sensor triggered warning now getting no abs or slip contol warnings on dash could...

abs problem will be a wheel sensor. if speedo working its not the pass side one. now for the lambda sensor. if you are traveling at 70 mph for 250 miles at a time this will over heat the sensor over time. as its a 2007 and normal running over time to replace them is 10 years. most that do over 500 miles a day would need to change them with in 2 to 3 years.

Hi, the level sensor in the reservoir has failed. Sometimes you can free it up by tapping on it. Otherwise, you may have to replace the reservoir/sensor.

Check Egine Light Stays On

Well if the sensors are defective the garage should warranty them,unless they are aftermarket products
then the warranty isn't so great.
If the shop that did the work determines that the sensors are a-ok then there may be a problem with the ECU or the circuit.

Engine warning light says lean bank 1 low.

generally aftermarket parts are made from the original toyota models so it is doubtful that is the problem. There may be a short in the wires that are causing the sensor to burn out. I would suggest first taking to your local auto parts store and have them scan the ECU for the problem. I hope this helps. Please rate this Thank you

The Nox sensor fits after the catalyst (non FSi models had a rear lambda) the lambda on your car is near the engine and has 5 wires because it is a broardband type.
The Nox sensor is a common fault on all FSi models

Engine light and emmisions worshop on dash

You will need to have another code scan done. A faulty glow plug will certainly show up on a scan, but should NOT bring on the engine MIL light. Erase all faults showing at present. This should extinguish the engine light. Thin start and stop engine a number of times until the light comes back on. This will re boot on-board computer. Do another scan and the fault should show up. If possible do a live reading, paying close attention to the (oxygen sensors) lambda units
Best of luck
