In a 1996 Ford Econoline 250 with a 4.9L 300 engine, the coolant temperature sensor is located on the engine block, near the thermostat housing. It is typically found on the driver's side, near the intake manifold. To access it, you may need to remove the air cleaner or other components depending on your specific setup. Always consult the vehicle's repair manual for precise information and guidance.
The 2001 Lexus coolant temperature sensor can be found on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.

It is built into the air flow meter.
The engine coolant temperature sensor is located at the timing belt end of the engine on the water outlet casting.
To change the coolant temperature switch on a 1993 Lexus GS 300, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the coolant temperature switch, typically found near the thermostat housing, and carefully disconnect the electrical connector. Use a wrench to unscrew the old switch, then install the new switch by threading it in and reconnecting the electrical connector. Finally, reconnect the battery terminal and check for any leaks after refilling the coolant if necessary.
follow top radiator hose away from radiator to a cast metal grey looking box,(for lax of description) you will see a single wire going to connector on left of box,that is one engine coolant sensor,right side of same box is another sensor with 2 or 3 wires,that is the other temperature sensor, one does instrument guage and the other does computer temp and tranny shift ( ok to shift to 4th signal when warmed up ) to computer and tranny computer. I have purchased them from autozone etc, but do not think the instrument version is quite the right range because when you first crank up and get to end of driveway ( say 300 ft) the instrument temp says its warmed up,which is wrong, you might want to get instrument sensor from KIA so you get right tolerance from sensor.

To locate and replace the cooling sensor on a 1999 Lexus GS 300, first, ensure the engine is cool and disconnect the negative battery terminal. The cooling sensor, also known as the coolant temperature sensor, is typically located near the thermostat housing on the engine. Carefully unplug the electrical connector, remove the sensor using a wrench, and replace it with a new one, ensuring a proper seal with any necessary O-rings. Finally, reconnect the electrical connector and the battery terminal, and check for leaks.
Most likely its not your mass air flow sensor its gonna be your tp sensor (throttle position) or your down stream oxygen sensor because a MAF sensor controls your ITS or Ideal temp sensor witch can affect your accel and your idle when under a load but when its at rest or idle it will be affected by a tp sensor of O2 sensor they call the O2 sensor the spark plug that never gets changed..
