Don't replace anything yet.

There is a procedure for checking the sensor, but the best thing for you to
do before embarking on expensive wild-goose chases, is to clear the code
from the ECU by pulling the "Backup" or "Hazard/Backup" fuse for 10 seconds
(on right shock tower, at rear of box).

Often these problems are intermittent and the error may not repeat.

(I had a VSS sensor error once a few years ago. I cleared the code and it
never came back.)

Your "ECT" part is also called the Thermo Wax sensor, and sends a voltage
to the ECU varying with how warmed-up the engine is.

If you have an automatic transmission, do you notice delayed upshifts into
top gear? Any other odd behavior? Any corrosion on the TW sensor wires or
connector?

If the code repeats and you have a multimeter, I can send you the check
procedure from the factory manual. It's easy to check.
