Are there sensors or computers in the engine that tell the instrument cluster/gauges what to display?

Question

Are these readouts given by some kind of sensor or computer?

1995 Buick Regal

1. RPM / tachometer readings

2. Gas gauge

3. Engine temp

4. Speedometer and odometer

5. Trip meter

How come I can't see the sensors for these gauges? Where are they located in the engine?

Answer 1

They are sensors.  I believe the Tach is located on the block.

The Gas Gauge is a sending unit located in the gas tank.

Enging Temp is also located on the block

Speedometer is located on the tranny, and along with the odometer too i believe.

What is the trip meter? same as odometer? if so then should be located on the tranny

hope this helps.

Answer 2

>>  Are there sensors or computers in the engine

Yes, there are about dozen sensors and a computer.

They are located all over INSIDE the engine.  And would you know a sensor if you saw one?

Good Luck...
