That's what I didn't know is if it went by speed or RPM. My TAC is working, speedo is not.
What had happened was when I installed my other motor I was a little hard on the powersteering pump and I messed up a line because on my test drive I blew a hose squirting fluid all on the back of the motor.. I tried cleaning it but on another test drive it cought fire on the back side of the motor.. Didn't burn long but it was enough to damage that chunk of harness (knock, oil pressure, rear 02, and that sensor) It also melted the top of that sensor. I have not driven the car enough yet to know if I might not of hooked something up right because it did not do it before the swap but is now.. Knowing if this sensor causes problems would put my mind at ease!!!
I have the new chunk of harness and I bought a new sensor since the top was damaged. I will fix it all this weekend since my steering issue is fixed so I'll find out, just trying to get a heads up on a what if..
