Unhappy Weird promlem w/ temp guage

Well I finished detailing my engine using gunk ( the degreaser) the other day. I covered all the electrics before and everything but the problem is now that I have finish my temp guage rests at all the way hot all the time. Its just totally dead. Does anyone know where the sensor is? or maybe a ground? I'm so puzzled. Thanx for any help you can give me, I appreciate it. Engine looks awsome by the way, much more fun to work on.

I still dont understand why people want to water their engines. Water is only supposed to go in the cooling system. Isn't this why we have a hood?

Sounds to me like either the wire for the temp sender is touching the engine (Possibley "washed" off during your cleaning evolution), or the wire is broken and is touching the engine.

Bosch uses NTC, or Negative Temperature Coefficient devices in both the in-dash gage and DME temperature sensors.

These sensors have a low resistance when hot, and a high resistance when cold. Thus, the NTC designation.

Since the gage is pegged high, this would indicate that there is little or no resistance between the gage and ground.

The sensor is located under the intake manifold towards the front of the engine. Look for a sensor with a single round flat terninal. There should be a single wire with a female spade connector attached to this sensor.

The DME temp sensor is in the same vicinity, but closer to the front of the engine. The DME temp sensor has the same style plug as the fuel injectors, and the sensor side of the connector is blue.
