That's the thing, I don't want to replace the sensor and find it was something else, hence sending it in for the diagnostic. If they say, "just the sensor, mate" then I will ask "how much?" and think of a threshold over which I'll say "thanks very much, here's the money for the diagnostic but I'd like to replace the sensor myself". But also likely spend more money on the suspension.
The only thing I'd be aware of is that if a code is thrown for a sensor, a faulty sensor is not always the culprit. It's possible that there could be another issue eg electrical/wiring. I know this from experience having replaced an extremely difficult to reach knock sensor on my other halfs CRV due to a code - EML came back on, same code. Luckily for me the genuine sensor was only pennies, but it was an absolute pig of a job for nowt!
