Exclamation broken sensor...

ok there is a 2 wire sensor directly under the black box with a yellow cap saying power steering, the sensor is connected to a rail, one of the wires has come out of the sensor and if i touch the wire to a grounded area such as the intake manifold it raises my rpms and makes a hissing noise from the black box above it, anyone know what this sensor is??

i have looked further and it may be a coolant temp sensor, this sensor hasnt sent a CEL, could this sensor also cause some other problems for idling and ect?

The coolant temp sensor is at the opposite corner of the engine.

From the vague description it sounds like the sensor for the power steering system. I just took a quick look in my basement, is it a green/white and black/white wire.

If you remove it, some fluid will drain out. Just lay a rag under there to catch it.

If you want to minimize the leakage, use a turkey baster to empty the reservoir first.

Idling is usually controlled by the IAC (Idle-Air Control) valve. A dirty one can cause bad idling.
