Hi everybody,
I have an fzj105 series, auto, petrol 1fz-fe.
Issue Im having is an odd one and somewhat hard to diagnose exactly what is causing it, Im looking for any advice possible at this point.
if the engine is cold I have to sit and let it warm up to at least a quarter on the temp gauge. OR if I just start driving the vehicle will begin to warm up but once it hits a quarter on the temp gauge it will bog down throw a chk engine light and put itself in limp mode. This doesn’t happen if I sit and let it warm up without driving it.
The code it’s throwing is a knock sensor 1 & 2. I have had this in my mechanics numerous times now and he can’t put his finger on what the heck is happening. They have tested the knock sensors and they are healthy, also have replaced the knock sensor loom to the ECU.
The engine/vehicle is otherwise in very good shape. I’ve spent $ thousands on restoring it to its a1 factory glory aside from this one issue with the chk engine code throwing, Iimp mode.
Any advice would be appreciated, it’s quite the odd issue indeed.
Cheers,
Sam
