Thanks for the info. So it would seem that someone has bodged the car and replaced the proper sensor with an oil light sending unit. I suspected that the switch trip point might be at a different PSI.In fairness the car has run for the last year and a half under my ownership without throwing the P0026 code. I guess I'll have to scrounge up the right connector an solder it in place as well as ordering the correct sensor..

Here's a pic of the oil pressure sensor that is on here now. Looks like a standard oil light switch. I'm picking up the correct sensor tomorrow and hopefully that will do the trick. Solenoid still appears to be functioning.
