What is wrong with the car it shows me p0432 code main catalyst efface below threshold (bank2), how do I fix it cause the engine light goes on and stays on?
The code means what it say. The car computer compared the data on amount of air/fuel injected in cylinders with the emission O2 reading from the Oxygen sensor in the air intake (the one after cat converter), and decided that the catalytic converter is not doing its job because emission is too high.
In some case the problem is occasional. Try resetting codes by disconnecting battery terminals (make sure you have stereo code if needed).
If the code comes back, then there are several parts to be tested before replacing cat converter.
Many times the problem is the converter itself. before replacing the converter the mechanic must check for problems resulting in wrong air/fuel mixture, as these may trigger p043.
Sensors in the air intake and air intake itself must be tested, check MAP sensor and intake structure for leaks. Replace air filter. Check the vacuum for leaks. Check IAC. Check O2 sensors.
If there is no problem under the hood, check the state of other parts comprised in the exhaust system and eventually replace the cat converter.
