MAP sensor is usually a square looking thing with a vacuum line and electrical connector attached to it. If you somehow meant the MAF sensor then it is located in the air intake hose near the throttle body. Hope this helps.
MAP sensor is usually mounted to the fire wall of the vehicle.

The coolant temperature is measured from the cylinder head temperature sensor CHT and is located on the drivers side cylinder head in the rear. It is connected to the harness by connector C107 and has gray/red and yellow/light green wires going to pins 39 and 55 of the processor.

The ECT (Engine Coolant Temperature) sensor is located either in the heater supply tube at the rear of
the engine, or in the lower intake manifold. The ECT sensor is a
thermistor (changes resistance as temperature changes).
The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM. From this signal, the PCM will modify the air/fuel ratio (mixture), idle speed, spark advance, EGR and canister purge control. When the engine coolant is cold, the ECT sensor signal causes the PCM to provide enrichment to the air/fuel ratio for good cold drive-away; as engine coolant warms up, the voltage will drop.

Hope this helps and keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment.
Have a nice weekend and thanks for using FixYa.

The Crankshaft Position (CKP) Sensor is a permanent magnet output coil device that monitors the speed and position of the crankshaft. A reluctor is attached directly to the crankshaft, and is used to generate a constant signal as it passes the CKP sensor magnetic coil. The CKP Sensor utilizes system voltage (12 volts DC), or reference voltage (5 volts DC) to generate a digital output signal to the PCM that is based upon a 0.5 volt AC reference. The alternating magnetic field is used by the sensor output electronics to produce a digital pulse. The CKP sensor returns a digital ON/OFF signal pulse during each revolution of the crankshaft, with a momentary signal interrupt for the top dead center (TDC) position of the #1 cylinder. The Pulse Width Modulation pattern is used by the Powertrain Control Module (PCM) to calculate ignition timing, fuel injector timing, misfire diagnostics, and the tachometer display
