Thanks.. I've changed my ECU... Now VTEC sensor light is gone... With 2nz ECU... My Check Engine light was there... And scanner showed VTEC sensor problem...
But hassan bhai... The ECU which i have bought now has no label above it... Shopkeeper said its 1nz Manual... I believe its manual because with auto it show gear lever codes... but how can i confirm its 1nz not 2nz r 1sz...
Checklight is gone now...

Toyota engines don't have VTEC. It's only for Honda. May be VVTI error is showing

Great
Not sure about model number. And not vtec, VVTI.
Now you will feel difference in mileage as well.

Yes, VVT sensor... Sorry.
