Dear fellows,
I want to share you some information regarding vitz to avoid any problem in future.
Mine is 2001 AT / CNG
Problem I faced:
Last week when I start my car , I feel that the engine sound is not normal , it has jerks / vibration
and car engine OFF after 2 minutes while it was on P. Anyways I drive my car back from porch using R
. When I want to go forward using D , the car I feel is very heavy and face difficulty to move . Meter show no increase in speed. I try to push throttle hard but it moves little bit and turn OFF.
Come story short it behaves same even in 2supnd/sup and 3suprd/sup attempt.
I decide to convert it to CNG , now its perfectly working fine and shows no problem but while driving on CNG
, I convert it to petrol for recheck and its give me same problem the speed goes down , more engine vibration and finally stop at road side.
The last thing which I did with car before parking:
I revised my memory that what I did last time with my car, Actually I drive back from Islamabad to Wah on CNG and often I shift it to petrol before 7 / 8 KM reaching my home .
BUT that particular day I forget to shift it to petrol , so when I parked it in porch I shift it to petrol and press throttle hard 2 or 3 times , so petrol circulate in system. THIS IS LAST THING I DID. And next morning the thing I felt I already share you above .
Troubleshooting problem and Solution :
First I parked my car for 3 to 4 days because I was so nervous that what todo next
and
go where , either TOYOTA or some one else , and don’t
have idea that how many they charge me for that .
ANYWAYS decide to look help from internet. I find 1 link in pakwheels with almost same problem and the guy mention that he went to Toyota motors and after test scan the engineer over there is unplug battery and hooked back after 2 minutes. ( resetting ECU)
Following is that link :

Anyway I decided to do the same as I have no choice before going to some workshop. So yesterday morning I unplug the –ve terminal and then after 1 minute I unplug +ve terminal . wait for 2 minute and then hooked these back. I read BISMILLAHA and start the car , I feel that now its starts same like as when it was OK.
I drive out from porch , start driving forward and its responds me even better , I drive it for next 30 minutes on different speed and its behaves extremely well.
MY ONLY INTENSION TO SHARE THIS PROBLEM
here is
THAT MAY BE SOME OTHER DAY YOU NEED THIS . SO BE CAREFULL DO NOT PUSH THROTTLE HARD WHILE on P and N or you gone confuse your ECU.
Thanks for your time , Regards , Ashar
