There are usually two throttle position sensors\/switches found on the intake manifold&rsquo;s throttle body, while there are pedal position sensors\/switches on the accelerator pedal. Their readings tell the powertrain control module (PCM) the amount of engine power needed and how fast the engine needs to produce it.<\/p>\n\n\n\n<p>If the PCM detects that the voltage output from the throttle position sensor is too low, it will log a P0222 code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P0222 Code Mean?<\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/blog\/search-obd2-codes-list\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Diagnostic Trouble Code\">Diagnostic Trouble Code<\/a> (DTC) P0222 indicates &ldquo;Throttle\/Pedal Position Sensor\/Switch &ldquo;B&rdquo; Circuit Low.&rdquo;<\/p>\n\n\n\n<p>Each throttle position sensor regularly sends a voltage signal to the PCM. The signal&rsquo;s voltage level varies according to the sensor&rsquo;s current position, which in turn depends on the vehicle&rsquo;s acceleration. Stepping on the <a href=\"https:\/\/www.carparts.com\/accelerator-pedal\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"accelerator pedal\">accelerator pedal<\/a> rotates the sensor, and its voltage signal tells the PCM just how wide the throttle has opened.
