Yes, the signal to the PCM can be wrongfully perceived as low coolant, even if the car is full of anti-freeze.
Yes. It does big time
Make sure you have engine coolant. If the engine isn't getting enough coolant, it will overheat, stall and possibly destroy the engine. One symptom is that no coolant is circulated into the heater. Also check the crank sensor, but check coolant first...then the crank sensor.
When driving the IAC does not do anything because the car is not at an idle
A bad crank sensor will definitely cause the car to stall. Eventually the car will stop starting up again, or if it does, it will die down around ten minutes. A good thing to do if you're sure it's the crank sensor, replace it.
yes..a bad oxygen sensor can/will make your car stall at idle speed
Yes, a faulty coolant temp sensor can do that.
The coolant temp sensor wire comes from the firewall area. An easy way to make the temp sensor work if you can not find it is to connect the sensor directly to the battery. The sensor uses wireless technology to send its data. It might take an hour or more of driving for the sensor to reset before it starts sending data to the computer. .
check you water (coolant) level, make sure thermostat is working, radiator leaks, sensor problem
Make sure it really is low on coolant by checking the coolant when engine is off. If the level is up to par, then the sensor may be bad.
Year, Make, Model, engine size please. possibly an ignition or sensor (electronic part).
Yes.
Some cars have a sensor in the reserve tank that sticks or the sensor on the engine is gone. Get a manual for you make and it will show the locations.
