Just another new member with a thanks for this thread!
Been having intermittent starting problems during damp weather and warm starts - had already tried the spark wires and plugs to no avail.
After reading this thread was able to locate the
Sensor in my 1998 Megane - took it out and gave it a good polish with sandpaper, WD40 and a toothbrush, and car has been starting every time since then!
Took longer to actually locate the
Sensor than it did to remove, clean and replace!
