Its electrical resistance shifts in response to the temperature of the gases it is measuring.<\/p>\n\n\n\n<p>When the temperature rises, the RTD&rsquo;s electrical resistance goes up. Conversely, a drop in temperature reduces the resistance. As the resistance shifts, so does the voltage drop across the sensor&rsquo;s terminals. This change is sent to the PCM.<\/p>\n\n\n\n<p>The EGT sensor&rsquo;s resistance will change according to the temperature of the exhaust gases.<\/p>\n\n\n\n<p>If the exhaust gases are too hot, they can damage the engine or turbocharger. The PCM keeps track of these gases through the readings from the EGT sensor. It will warn the driver about excessively hot exhaust gases and take steps to prevent damage to the engine.<\/p>\n\n\n\n<p>The PCM regularly checks the exhaust gas temperature sensor. If the computer doesn&rsquo;t get the right response, it will set the powertrain code P0546.<\/p>\n\n\n\n<p><strong><em>Note:<\/em><\/strong><em> The definition of code P0546 can differ according to the vehicle manufacturer.
