I have two S5 N/A engines... but one has an oil pan that has two sensors in it, the other one just has one?

What is the extra sensor? It's next to the level sensor... small, one wire... kind of looks like the gear position sensor on a transmission... but I'm not inclined to go unscrewing it not knowing how well it's sealed hehe.

engine oil temp, Turbos and some n/a's have them.

 

I figured it'd be that, thanks Karack.

Now I just gotta figure out whether my car can use that or not haha... happen to know where it plugs in at? (The wire is cut I think but I didn't look too closely)

Oil temperature sensor for the Sub-zero start assist system. If your car does not have that oil tedmp sensor from the factroy, it ALSO does not have the sub-zero start assist.

 

The cold start is built onto the intake somewhere right?

I'm thinking since my old block didn't have the sensor at all, I'll leave this one unplugged... until I decide to hook up a guage or something to it. =)

Does anyone think that will cause any problems? Apart from the short-block everything will be from the engine that didn't have the sensor.

It is a switch. Switch as in ON/OFF. It is part of what was said above, the Sub-Zero Start System. It is described in the free online fsm that is linked in this site. The Fuel Section. The very, very last thing in the Fuel Section.

 

Thanks I have the FSM of course, I'll take a look when I feel like messing with it heh.

i thought the sub zero was that ghey *** coolant tank that sits on the passenger side of the firewall. might want to see if there is the tank there to save you some time.

 

Considering I have no idea what tank you're talking about I think I'm cool. lol

Bob, your acting normal today. Read the fsm when you get around to it. It's not worth reading for this item.

The temp SWITCH in the oil pan told the Sub Zero System when to get off it's butt and take action during startup. The tank was located in the right rear of the engine bay near the charcoal canister. It was suggested to be removed on a factory service bulletin.
