I think you are right guys this lexus must be replaced with something much better ,o think Tesla is not bad solution.

lexus is more like hobie car to practice and improve some stuff but tesla looks like way to go.

Even Joda agreed that tesla is better than Lexus es 300h.


cheers.

 

Great. Once you get your Tesla there is the EV forum.

 

Really ,i didnt even know that ev forum is here ,thank you is nice to have wise guys like you around.

 

I will try to do diagnose next week and i will tell you results.
thank you for your help ,

 

hi there,
it was a while since i posted any update on this ongoing problems wit ES 300H
new throttle body installed no improvement's
new ECU installed and reprogammed using paper clip about 30 min. no improveme;;ts
new MAF SENSOR no improvements
new gas pedal with position sensor installed no improvements
HERE WE GOT additional P2135 CODE

finally bypas one wire by throttle body 12v no improvement's

reading was confusing on multimeter we always got about 11 or 11.2 v on other side of connector
and here is what happened....

 

one simple wire which was causing false reading on multimeter

hint

recharge 12v small battery .pump it about 13.5 v than check reading on +BM WIRE it was about 11.5 V even 9 v

THAT WAS REASON WHY CAR STARTS 2 SEC THAN STOPS

GET NEW FEED FROM FUSE PANEL WITH PURE VIRGIN 12 V AND FEED ECU AND voilà

CAR WILL START AND RUNNING GOOD AGAIN

sorry i am to excited now that after almost 1 year problem has been solved .will posted pictures and data and shop manual procedure soon


still my tesla is ;much better .but i was using one hint from tesla to make lecus es 300h running again

ps..... all new parts we put in this car not needed and i gave to ;my neighbour to uppdate his lexus

 

After enjoying few days recent success with enabling ES 300h we did now hooked up to tech stream software just to confirm why
throttle position was ON all the time
now after BYPASSING connections
throttle possition is OFF and goes BACK ON after you start engine.

next we have to cleanup with 44K by BG ,oil change and some other minor things,air filter,cabin filter ,etc etc.

Here we can see that position of throttle sensor Off
