820-3437 Failed TIM Test - Plimit not as expected -Processor

Board/ Mac appeared to have no liquid exposure or drop damage. Light, no power.
Found R7236 had some corrosion and C7374 was bad. Replaced these and R7237.
Powered on but failed the Processor TIM 0 and TIM extended tests. Appears to think the CPU temp is not appropriate?

Also, after looking over the board I’ve replaced U1845 and U3710.

Do PRAM reset first.
SPI chip isn't touched?

I hope you didn't put a normal resistor in place of R7237; that is NTC...

Swapped all components from a like donor.
SPI area looks fine. Board wasn’t ever touched or even removed prior.
Will do PRAM once out of the ultrasonic.

I read on another post that on a retina the battery can affect the Plimit? Never seen this failure before and have run plenty even with no batt.
 
I was about to consider it done and call it an ASD issue because it seemed to operate normal..
However, I checked the U7200 area - everything measured normal but u7200 seemed off a bit. Replaced and it passes all diagnostics now.
Thanks for the help. We can mark this one solved.
