Why is 01 Ford ranger 2.3 boiling over within 5 minutes of driving it. The engine light is on and the code showing is P1432-thermostat heater control. the hot coolant smell is strong. can anyone help?

P1432 - Thermostat Heater Control (THTRC) Circuit Failure The Comprehensive component monitor (CCM) monitors the THTRC circuit to the PCM for high and low voltage. If during testing; voltage was to fall below a calibrated limit for a calibrated amount of time the test will fail and set the DTC and MIL. Open or shorted THTRC circuit
Open VPWR
Open or shorted thermostat assembly
Damaged PCM
DTC P1432 is a THTRC circuit check. Testing should include wire harness, thermostat heater and PCM. I know this description is a little complicated. You MAY have a blockage in the cooling sytem somewhere. To start, pull and check your thermostat (front of engine) If you replace it make sure you replace it with one that is the correct OEM temperature (like around 190 degrees). A lower temp stat will not help, it will hurt! Get the engine to cool, don't worry so much about the CEL(they call it the MIL). Something like Malfunction Illumination Light. DTC is the Diagnostic Trouble Code. The PCM is the Power Control Module (main computer). Also make sure the water pump works correctly and the radiator has no blockages.

Your temp gauge doesn't work how do you tell when your engine is running hot before the car stalls out and the coolant blows everywhere?
if your temp gauge is not woking you will know it what you already said it it will boil coolant and stalled. other way around is open car hood every 3to 4 miunts of driving and look at at your over flow resvoir to see if the coolant is boiling in there. best advice is to gft this thing fix asap. if your temp gauge is not woking you will know it what you already said it it will boil coolant and stalled. other way around is open car hood every 3to 4 miunts of driving and look at at your over flow resvoir to see if the coolant is boiling in there. best advice is to gft this thing fix asap.
After driving Car drops all coolant from coolant tank sometimes after turning car off?
check hoses coming from coolant tank by sqeezing may be worn
Driving with no coolant?
Very bad idea. engine damage will result.
Can bad driving cause oil and coolant levels to go down drastically?
Hard driving can cause an engine to use oil, but not drastically. Coolant level should not be effected unless the engine overheats.
What is the main cause for dodge caravan overheating when driving slowly in traffic?
Low coolant or an inoperative radiator fan.Low coolant or an inoperative radiator fan.
Can driving your car after you found gas in your coolant make the engine problem worse?
Yes
Why am I losing coolant in the reservoir while driving?
could have a crack in it that is leaking under pressure
How do boiling points affect evaporation?
Boiling point is where the vapor pressure of a liquid equals the ambient pressure. The closer you are to the boiling point, the more driving force there is for the liquid to evaporate until it saturates the surrounding air.
Why do cars use collant instead of water?
Coolant, also known as antifreeze, serves two purposes in a cars engine. (1) Coolant keeps the engine cool. During the summer especially, your engine can get very hot. We all know that when water gets hot enough, it boils. Have you ever seen a car on the side of the road, with a bunch of steam blowing out of the hood? That is a car with an over heated engine. Coolant can still boil like water, however coolant has a higher boiling point than water. (2) Coolant also keeps the engine from freezing. This is very important. If your cars engine has water in it, instead of coolant, and the outside temperature drops below freezing, your engine may become susceptible to becoming frozen. If your engine freezes from sitting in the cold without coolant, the water inside of the engine will expand. When ice expands it has to go somewhere. You engine will crack and will not be repairable. Coolant can still freeze, but unless your using the lowest grade coolant, and your driving through Alaska, your coolant probably won't freeze. How does coolant both keep the engine cool when running, but keep it from freezing too? Its simple; Coolant has a higher boiling point than water (99.7'), and it has a lower boiling point than water (32'). The temperature highs and lows vary with the type of coolant you use. !CAUTION! When your coolant level goes down, due to evaporation or leaks, you may out water in your radiator for a temporary fix. HOWEVER this alters the highest and lowest points of your coolants temperature peak. MORE WATER = WATERY COOLANT
Why is 2001 coolant temperature gage sometimes goes from 190 to 0 while driving and vice versa?
the coolant temperature sensor is faulty. It will need to be replaced
What is an overflow tank?
An overflow tank is a bottle that holds coolant that expands and leaves the radiator under driving conditions. The Coolant will go back into the radiator as needed.
Can a coolant sensor make your car stall when I'm driving?
Yes, the signal to the PCM can be wrongfully perceived as low coolant, even if the car is full of anti-freeze.
