Code 71 Egr Temp. Sensor

[dfila]

I recently had my computer replaced on my 1992 SC-300.

Even though the car runs good, I got a code 71 (check EGR temp sensor)

I took it to Lexus and they cleaned out EGR valve. I still get the code.

They say that EGR valve has NO temp sensor attached to it. and asked Did You Replace IT? No I didn't!!

I think the replacement computer is newer and is looking for the EGR temp sensor and I don't have one

Do I have to get a New EGR valve and Temp sensor as Lexus suggests ($540) or can I somehow fool the computer into thinking it has a EGR temp sensor.

Some people modify the EGR and block the flow with a kit and somehow get that to work. Maybe that is the solution.

Thanks,

Don
