1rz-e throttle body


Recommended Posts

hi guys


got a 2001 2l lux with the 1rz-e motor when it’s warm it surges bad. seems to be the coolant controlled idle valve is the issue as the output of the coolant hose water pluses to match the rpm indicating it’s open and closing i’m time with the rpm’s.


it looks like this is a sealed unit and part of a whole throttle body that is rare as and $1300 for toyota 🤦‍♂️.(pn 2221075121)


the screws come of the back plate but it’s a solid unit inside.


any ideas on a fix or where to find a new unit.
