oil pressure sensor

[kenny8076]

hey i just bought an oil pressure sensor and everything looks right except I'm a little questionable about the yellow wire, now i couldn't see a whole lot of the one currently on my car but the one i just got is about 3 maybe 4 inches. is that right? for some reason when i look down at the one on the car now it looks longer. i could be wrong because i cant really get a good look at it with everything else in the way but just want to make sure before i start working on it tom. ive been reading to take the starter off and its accessible (though still a little hard to work with), if theres any other advice feel free to share.

That sounds about right. The connector for the sensor is cable tied to the solenoid/starter motor in the bay to the rear of the engine.

I found access was easiest from below. There are some pictures here.

To undo the old one some people cut the wire off, I found you could pass it back down a 25mm 12 point socket out of one of the spare points. All those ways damage the wire though.

Inserting the new one needs a finer technique. Some use a 24mm ring spanner, some cut that short as there is little room. I found a 25mm ring was sloppy enough allow it to clear all the obstructions and it is not a high torque job so a poor fit on the nut is not a huge issue.
