Overheating Issues

[Rodeotexas122]

I have a 2002 corolla and the engine has been messing up. Threw coolant temp sensor code so changed it. After five temp sensors one finally worked to get the gauge moving but now shows it's running really hot after less than five minutes of being cranked. Changed the thermostat. Temp sensor. Intake and exhaust manifold gaskets. Runs like crap now and still saying it's over heating.

How do the wires and the connection look? And where are you buying the sensors? The car is running like crap because it is in limp-home mode from overheating. Is the water pump in good shape?

I have bought a temp sensor from autozone, orilleys, and advanced auto parts. None worked. Connector and wires look good. Water pump looks good to.

If all of that checks out, last possible thing is scale build-up in the cooling system. Gonna need to flush it.

Diagnose coolant flow inside the radiator. Diagnose the thermostat. Diagnose for a plugged radiator.

Don't replace anymore parts.

Plugged in the old temp sensor and it doesn't show it over heats anymore but check engine light is on.

What's the code?
