how toyota smart keys works
how smart keys works

Smart key is a key fob to start vehicle and lock and unlock vehicle
you must have a key fob inside pocket or close to vehicle, if you have key fob
in your pocket and when you go to unlock the vehicle you do not need to unlock vehicle
with key fob, if you have key fob in your pocket you just need to pull vehicle door handle to unlock
vehicle and door will be open, and for starting the vehicle you also have key fob in your pocket or closer to vehicle
and just press the brake padal and press the push start button to start the vehicle
if you just press the push button, without pressing the brake padal then your vehicle switch will be on and no start engine untill you press the brake padal.
To check smart key is working or not just go near the vehicle and try to open the door by pulling the door handle if vehicle door do not open then unlock the door first with key fob unlock button, if door do not open with key fob the put out the key and from key fob and open the door with machinal key
and get inside the vehicle sit on driver seat and press the brake padal and look as you press the brake padal and see push button light illuminate or not

How to check smart key is working or not
How to check smart key is working or not

 if do not illuminate then change the key fob battery.

if after changing the fob's cell you are getting problem then take vehicle to near dealership.

In this post I will tell you some important things which leads a vehicle engine no start

If your crank and no start then see below some main things to point out fault

No 1# First of all turn ignition on position and check engine ligh is  is
illuminating or not if working then go to step no 2 and if not illuminating then check EFI fuse
if fuse is burnt then replace that

No 2# Second step is check security system by checking your blinking light in obo meter or 
anywhere on dashboard that ligh start blinking as you removed key from switch and gets off
as you insert key in switch, get key of vehicle out from switch and light will start blinking
and as you insert key in switch withourt turn on switch light will get off if this step is okay then go to step 3, if you removed key out and light is not blinking then there may be problem in immobilizer
just replace it. and check vehicle

No 3# Third step check fuel system is working, you just need to first check fuel pump is working by hearing noise of fuel pump, if you did not hear noise of fuel pump then you need to open the fuel line which goes to injectors and switch on and try to start vehicle for a second if fuel system is working then you see fuel in getting out from pipe if fuel is working then see step no 4

No 4# Fourth step check crank sensor with multimeter if there is no connectivity or showing connectivity too high then replace crank crank sensor

No 5# Fifth Step if all things above are okay then Check sparks in plug if plugs have spark then do step no 6

No 6# Sixth Step you need to change fire plugs, If after changing vehicles is not working
then you need to test vehicle timimg belt if there is timing belt broken vehicle engine crank fastly and vehicle change its engine sound.

Many of Toyota Vehicle which have a electronic trottle control system attempt this fault when we release the vehicle peadal then vehicle gets off, lets come to know why this fault accured
when we disconnet the battery connector for a 10 to 20 minutes or more or we removed the battery and we just remain switch on and the memory of trottle control gets lost and then you need to relearn your trottle control, by just cleaning the the trottle body, one thing if there is this problem The MIL lightdo not illuminates,

to test there is problem in trottle body or trottle body need to have clean you just need to try this trick to know trottle body have problem or not, just you need to remove the connector and start vehicle and check if vehicle is idle standing then you need to clean trottle body, if vechile is still have a problem then you need to check air leakage, I mean check other pipes, like brake pipes there may be problem and vehicle engine is getting air inside which leads vehicle to gets off as release gas pedal.


Dear vister

First I will tell you why this error show in during scaning vehicle when the sensor is short it show circuit high in scanner and when the coil is week then it show circuit open or circuit low

When there was problem accured in communication with sensor and the magnetic gear if it provide low magnetic field or high magnetic field then is ECM do not able to point out the exact speed so it show the mailfunction in scanner

In vehicle there was problem in tire hub sensor gear which was not communicationg with sensor and was showing the sensor mailfunction

Welcome dear vister

In Oxygen sensor there comes four wires
Two are black, one is blue and other is black

check oxygen sensor with multimeter
if there is connectivity in both black heater wires then
sensor is okay otherwise replace the sensor

many of times people wash the the sensor and re-install that again and
do not get any benefit

so first check the continuty of both black wires
if that have contibuty then clean that and re-install
you will get result
