It is located under the intake manifold. The manifold has to be removed to access the sensor.

Headlights are mostly individually fused these days and details are usually found in the vehicle handbook.

I used to work on taxis quite a bit and I noticed the drivers who smoked had many more electrical problems including switches than non-smoking drivers.

Check the owners manual for the car. If you don't have one, you can probably find a free download on the internet.

Yadayada ,don't know where you came up with that . This vehicle has just one ECT - engine coolat temp. sensor . It's an input for the PCM - engine computer . The PCM sends this info to the instrument cluster over the class2 serial data bus. . The proper way to diagnose a problem like this would be to hook up a professional scanner an check input data to the PCM , an instrument cluster . Not guessing an replacing parts .
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 60°C (140°F) or below if:
• The PCM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.

What engine ? could have come with a 3.4 or 3.8 L .
Engine Coolant Temperature (ECT) Sensor (L36)
Left side of the engine, below the thermostat outlet

Engine Coolant Temperature (ECT) Sensor (LA1)
LH side, top of the engine

Both are close to the thermostat housing , do you know what an where that is ? Follow the top radiator hose to the engine , should be near there . Look at the new part ,can't you match it up.

Check your fuel pressure. And your fuel pressure regulator.

Sounds like a voltage problem. Have Charging, Starting , and battery system load tested.

It's behind the hazard button on the instrument panel. You have to take out the instrument panel bezel to get to it. It controls both turn signals and emergency flashers.

It sounds like you might have plugged EGR passages. When the EGR valve opens, it should allow a measured amount of exhaust gases to re-enter the cylinders. This dilutes the air/fuel mixture to reduce certain emissions. When the computer tells the EGR valve to open it watches for signs that there is the proper flow of exhaust back into the cylinders. If it does not see the proper flow of exhaust, it sets a code P0401- EGR insufficient flow detected. The problem is sometimes the EGR valve itself, but since you replaced that, it is likely that the passages that the exhaust flows through have become plugged up with carbon.
To clean the carbon out, you can remove the valve and start the engine. With the engine at operating temperature, pour a small amount of combustion chamber cleaner into the passages. Don't pour too much in or you could cause a hydraulic lock in the engine which can cause major damage!!!
Be super careful when doing this as combustion chamber cleaner is extremely flammable and you are working with a running engine. You don't want to end up on fire!!!

Park, Tail, Marker Lamps, and License
The park, tail and marker lamps, including the license lamps, turn on when the headlamp switch is placed in either the PARK or the HEAD position, or anytime the headlamps are requested. The RT I/P #1 fuse in the RH I/P fuse block supplies battery positive voltage to both the park lamp relay switch contacts and to the park lamp relay coil circuit. The park lamp relay coil is controlled by the body control module (BCM). When the headlamp switch is placed in the PARK position, the BCM energizes the park lamp relay coil control circuit.
Current flows from the park lamp relay switch to both front and rear park lamp fuses and to their respective park/tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302. The inadvertent power control feature prevents the park lamps from remaining on more than 10 minutes if left on. If the park lamps are turned on after the ignition switch has been turned OFF, or is in the ACCY position, they will remain on until turned off or until the battery runs dead.

Did you the REAR PARK LP fuse 15 amp in the right insturment panel fuse box.

Ignition switch maybe ? Do you know how to do automotive electrical testing with a volt meter ? Pull the covers off the steering column to get at ignition switch electrical connector , then look at a wiring diagram to see which wires should have B+ voltage in the on - run position ! See if the B+ voltage drops out or just isn't there . You can find free wiring diagrams here
http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine . Under system click electrical distribution ,then under subsystem click on power distribution .Click the search button then the blue link . scroll down the diagrams till you see any that show the ignition switch . Check all the wires that should have B+ power in the run position . I know GM has had ignition switch issues .
The starting of the vehicle is computer controlled ,when you turn the key to start ,this sends B+ voltage to the PCM - engine computer which will then energize the starter relay ,thier by cranking the engine .

check for loose / dirty ground wires and points
indicates a voltage circuit being broken and the ECM is loosing voltage to work
