The thread is very old, but, sMARTINside, do you still have an extra 89420-20140 that you would be willing to part with? We have two ST185's in the family and would really like to have a spare of these. Let me know if you do.sMARTINside":36f2zv4l said:That is a 2nd gen sensor. You should use another 2nd gen map sensor, to be sure that you have the right one. 89420-17030 seems to be a Turbo MR2 sensor, from my search. 89420‑20140 would work too, I think. My ST185 had that sensor from the factory. If you ever want 89420‑20140, I have 2 of them and I have a 89420-17030. Where are you located?
