thermometer
The word that measures temperature is spelled "thermometer".
TEMP
No. Ambient measures the under hood, or outside temp not the intake itself.No. Ambient measures the under hood, or outside temp not the intake itself.
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
One measures temp other barometric press
measures the ambient air temp (outside air temp) and sends that info to the computer to adjust air/fuel ratio for best burn.
The air temp sensor measures the temp of the incoming air. cold air carries more oxygen while hot air carries less. so according to the temp from the temp sensor the cars computer can accurately adjust the the amount of fuel to be mixed with the air into the engine. Note: there are other sensors that the computer uses to get the right air/fuel mixture.
no iat measures intake air temp maf measures amount of air (volume) so pcm knows how much fuel to keep proper fuel mixture
a IAT or Intake Air Temp sensor is usually in the air box, since it measures intake incoming air temps.
temp = a; a = b; b = temp;temp = a; a = b; b = temp;temp = a; a = b; b = temp;temp = a; a = b; b = temp;
Well there are 3 sensors in my 1983 280ZX and I suspect it's the same with yours. There is a thermotime switch, which measures the temp and sends a signal to the fan when the ignition is turned off I think. There is a water temp sensor. Then there is a thermal transmitter which sends the temp information to the dashboard in my digital dash. I really don't know how close this matches your 77 though.
IAT=intake air temp sensor. it measures the temp of the air entering the throttle body. It is generally located on the rubber air intake hose between the air filter and throttle body. Hope this helps.
