This could happen for several reasons, and you&#8217;ll need to figure out why this code was activated in your situation.<\/p>\n\n\n\n<p>A restricted emission as a result of the turbo turbine being coupled to the engine and blocking it might cause low turbo boost control.<\/p>\n\n\n\n<p>As a result, the engine is obliged to push harder against the exhaust, lowering the quantity of energy that can be transferred from the cylinders for generating engine power.<\/p>\n\n\n\n<p><strong>The P226C diagnostic code indicates a problem with the turbocharger boost control. The P226C code is summarized and clarified in the following sections.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does P226C Code Mean on Cummins?<\/h2>\n\n\n\n<p>P226C is an OBD-II generic code. The engine control module (ECM) monitors the variable geometry turbocharger electronic actuator and has detected a problem with the turbo control. The ECM then activates the Check Engine Light and stores the P226C code.<\/p>\n\n\n\n<p>The Boost Pressure Actuator is a DC motor controlled by electricity that regulates the Turbocharger&#8217;s boost pressure output. The Boost Pressure Actuator is attached to the turbocharger assembly on the side.<\/p>\n\n\n\n<p>The ASD circuit provides a 12-volt power supply to the Boost Pressure Actuator, and the Powertrain Control Module provides a duty-cycle control signal (PCM). Data is sent between the Boost Pressure Actuator and the PCM through CAN Bus lines.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of Getting the P226C Code on Cummins<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"500\" src=\"https:\/\/www.motoraudit.com\/wp-content\/uploads\/2022\/03\/turbocharger-slide-ring.jpg\" alt=\"turbocharger slide ring\" class=\"wp-image-8581\" srcset=\"https:\/\/www.motoraudit.com\/wp-content\/uploads\/2022\/03\/turbocharger-slide-ring.jpg 700w, https:\/\/www.motoraudit.com\/wp-content\/uploads\/2022\/03\/turbocharger-slide-ring-300x214.jpg 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/figure><\/div>\n\n\n<p>There are certain mechanical faults, such as slide rings binding on guide pins, and a few issues with housings cut improperly, causing the VGT turbocharger slide ring to jam within the housing.<\/p>\n\n\n\n<p>Most turbochargers with mechanical or manufacturing issues are changed as a result of the &#8220;CHECK ENGINE&#8221; light going on and triggering the DTC P226C.<\/p>\n\n\n\n<p><strong>Therefore, a few of the symptoms of getting the P226C code are:<\/strong><\/p>\n\n\n\n<ul>\n<li>The Check Engine Light will illuminate, and the ECM memory will store the fault code P226C.<\/li>\n\n\n\n<li>With little or no turbo boost, the engine will struggle to accelerate or operate well under load.<\/li>\n\n\n\n<li>If the ECM enters failure management mode, the engine&#8217;s power may be lowered.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">The Causing Factors of the Error Code P226C<\/h2>\n\n\n\n<p>The several causing factors of the P226C code are given below:<\/p>\n\n\n\n<ul>\n<li>Through the CAN connection, electronic sensors on the turbocharger actuator monitor turbo vane position and send turbo vane position and boost amount feedback signals to the ECM.<\/li>\n\n\n\n<li>An electronic turbocharger actuator.<\/li>\n\n\n\n<li>A faulty turbocharger or clogged vanes.<\/li>\n\n\n\n<li>An open or short on the turbo controller&#8217;s returning signal control wire to the ECM.<\/li>\n\n\n\n<li>The ECM has a flaw or deficiency on the inside.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Read Also:<\/strong> <a href=\"https:\/\/www.motoraudit.com\/p2262-code-6-7-on-cummins-and-fix\/\">What Is P2262 Code On Dodge Cummins?<\/a><\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">How Serious Is Code P226C on Cummins?<\/h2>\n\n\n\n<p>The P226C turbocharger control code indicates that the turbo is damaged and should be replaced.<\/p>\n\n\n\n<p>If the turbo vane is stuck in maximum boost mode, there will be no turbo boost, resulting in a loss of engine power and perhaps severe engine damage.<\/p>\n\n\n\n<p>This might cause the engine to over-boost, which can be harmful.<\/p>\n\n\n\n<p>The ECM will record the P226C error code in its memory if it detects a mechanical issue with the turbocharger sliding ring.<\/p>\n\n\n\n<p>In addition to storing the fault code, the ECM will take a &#8220;Snap Shot&#8221; of all other sensor readings or data parameters at the moment the problem occurred and save it as a &#8220;Freeze Frame.&#8221;<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Read Also:<\/strong> <a href=\"https:\/\/www.motoraudit.com\/p1193-code-on-dodge-cummins-and-fix\/\">What Is P1193 Code on Dodge Cummins?<\/a><\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">How to Solve the P226C Error Code on Cummins?<\/h2>\n\n\n\n<p>This error code, like the majority of others, requires the use of a basic code scanner to diagnose.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"500\" src=\"https:\/\/www.motoraudit.com\/wp-content\/uploads\/2022\/03\/Cummins-6.7L-Turbo-Actuator-Replacement.jpg\" alt=\"Cummins 6.7L Turbo Actuator Replacement\" class=\"wp-image-8582\" srcset=\"https:\/\/www.motoraudit.com\/wp-content\/uploads\/2022\/03\/Cummins-6.7L-Turbo-Actuator-Replacement.jpg 700w, https:\/\/www.motoraudit.com\/wp-content\/uploads\/2022\/03\/Cummins-6.7L-Turbo-Actuator-Replacement-300x214.jpg 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/figure><\/div>\n\n\n<p>The Turbo Electronic Actuator has failed, according to the code P226C you have.

Because the issue is low air pressure, you should pay special attention to the airways. Make every effort to keep the airflow regular.<\/li>\n\n\n\n<li>Finally, do a re-scan on the engine. I&#8217;m hopeful that the problem has been rectified. If the code shows on the OBD 2 screen, see a local professional technician.

If your car has an over-boost problem, don&#8217;t drive it until it&#8217;s fixed.<\/p>\n\n\n\n<p>Make sure your vehicle&#8217;s engine is switched off if you want to undertake the repairs yourself. It&#8217;s never a smart idea to work on a reciprocating engine.<\/p>\n\n\n\n<p>This will result in a potentially fatal situation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Vehicles with the P226C code should not be driven since they may fail or become weak at any time. If the car loses power suddenly while traveling in traffic, it may cause an accident.<\/p>\n\n\n\n<p>I hope our discussion today provided you with all of the information you required. When a Cummins&#8217; P226C code was triggered, it was all over. Keep track of the code and try to resolve it as soon as feasible.<\/p>\n\n\n\n<p>Consider all of my recommendations and, if necessary, seek expert assistance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Code P226C indicates that the turbocharger boosts control \u201cA\u201d slow response.
