The reed switch will rarely give problem. Check the magnetic float then see where is the water goes at constant high rpm. I put 2 cm above the max water level and so far don't see any light coming up yet.

thanks guys....I bought a GT tuner which usually clips in the air intake sensor, since the 8 has 5 wires the instructions reccomend to clip it to the CTS sensor. I am sure its not gonna make much of a difference in performance or fuel efficiency as the product brags but thought of giving it a try.

MM knows a thing or two about our PCM. I'd listen to him.

CTS and Squirls
Saturday my 8 started and died. I'm like great, its flooded now. Finally got it started and noticed my check engine light was on, the stability control dash light was on, and my engine temperature wouldn't budge. OBD said CTS failure. Bought one after finding the location on this thread so I could replace it. Looked for the CTS sensor and found a bunch of acorns beneath it and a chewed green wire on the connector. Took nearly two hours trying to splice that sucker as its a very tight fit. Found a bunch of acorns under the airbox also. Squirls and chipmonks love RX-8s too. I'm buying a BB gun.
Thanks for the schematic.

Issues upon replacing sensor
So I took on the project of replacing my engine coolant temperature, didn't drain the coolant and did spill some on the engine block where the fuel injector is. Cleaned up a little. Now the car stated just fine before replacing but I CEL for this sensor and my traction control light also comes on when the sensor glitches. However after replacing I can not get my rx8 to ignite the starting system sounds healthy. It almost seems there is no spark. I did purchase the part off of eBay for cheap thinking this was a universal part. Anyone have any suggestion on what could be the cause for my car not firing?
