Will the exhaust pipe temperature sensor still consume urea if it is damaged?

[McEllie]

The exhaust pipe temperature sensor will no longer consume urea if it is damaged. Introduction to the automotive nitrogen-oxygen sensor: The nitrogen-oxygen sensor, abbreviated as NOX sensor, is used to detect the nitrogen oxide content in the engine exhaust. Working principle: Basic working principle of the nitrogen-oxygen sensor: Under certain conditions, the oxygen concentration difference on both sides of the zirconia generates a potential difference, and the greater the concentration difference, the greater the potential difference. The oxygen content in the atmosphere is 21%. The exhaust gas from rich mixture combustion contains virtually no oxygen, while the exhaust gas from lean mixture combustion or misfire contains more oxygen, but still much less than the oxygen in the atmosphere. Under high temperature and platinum catalysis, negatively charged oxygen ions adsorb on the inner and outer surfaces of the zirconia sleeve. Since there is more oxygen in the atmosphere than in the exhaust gas, the side of the sleeve connected to the atmosphere adsorbs more negative ions than the exhaust side, creating an electromotive force due to the ion concentration difference.
