Oil pressure sender / sensor socket size?

[tima4444]

Hi all, first post on this forum!

I'm getting intermittent oil light and limp mode on my 2007 Speedster 215 HP 4TEC. Checked oil pressure it's 90 psi at cold start/idle, 36 at hot idle, 60 at 3500 rpm and 82 at ~7600rpm. I'm thinking first I'll change the oil pressure sender/switch at the back under the intake (1 wire connector) to begin with. Anybody know the deep socket that I'll need? It's in a PITA location.

Replaced the oil pressure switch, solved my issue completely. For the record, the 13/16 spark plug socket is a just a tad too small, the socket size is 21mm. Thanks ski-d00.
