well I dont know that car, but if you know where the camshaft is (middle of the engine) look where the front cam gear is. Its got to pick up a signal from the gear/magnet.
It sounds like your idle control valve is sticking. The video shows you where they are located on a 97 Buick but it is the same engine.
This video shows you how to replace them.
You mean 4,000 rpm . No engine goes 40,000 rpm . senor on the transmission that control the rpm. No SENSOR on the transmission ! Crank sensor's Take it to someone who has a tool like in the video an knows what he is looking at .

The coolant temperature sensor is a thermistor mounted in the engine
coolant stream. A thermistor is an electrical device that varies its
resistance in relation to changes in temperature.
For 2.5L engines, the coolant temperature sensor is located on the left side of the cylinder head.
For
MFI engines, the coolant temperature sensor is located on the intake
manifold water jacket or near (or on) the thermostat housing.

I would suggest having the vehicle put on a scanner and monitor the operating parameters of the sensor for heater signal operation and sensor performance. You may not have overlooked anything. However, without knowing what the sensor is actually doing nand reading, you will be chasing your tail
Find the radio station you would like to store. Then press and hold down the button you wish to assign to that station until you hear a BEEP. That station will then be stored to that button.
Check the battery,have a load test done on the battery,now,it could be that the battery terminals,and battery cable ends are corroded,clean them really good,shining clean,this makes a big difference.Good idea to have the alternator checked also,while on the vehicle running,with the head lights on,and high blower motor,it should read at the battery,13.65 volts,to 14.25 volts.
If you follow up the brake pedal towards the steering column, you will see the switch.The switch can be at the front of the pedal or at the back of the pedal. It's not a difficult replacement, it's just hard to lay on your back in that small space and do the job. The part costs about $10.00. The question I have is why are you looking to replace? The faults are usually brake lights stay on which will kill your battery , or switch is bad and brake lights don't come on when pedal is depressed. I would first check for blown fuses, and blown bulbs. If you need any additional help please get back to me. GOOD LUCK FREIND.
i had the same problem had to replace the turn signal switch....GM for some reason wired the brake lights through the turn signal switch. to check if this is the case with yours. put some pressure on the turn signal lever as if you were going to turn on your brights and press your brake pedal and see if the lights work at that point that is how i found mine. hope this helps. if indeed they work with pressure on the turn signal lever. the new switch cost me $60 at autozone and that is with the steering wheel radio controls, make sure you get the proper switch should be part# sw771 if you have the radio controls on steering wheel and you will need a steering wheel puller and lock plate compressing tool.
