For example, on a Ford V8, the cylinders are numbered 1 to 4 on the passenger side bank and 5 to 8 on the driver side bank. On a Chevy or Dodge V8, the cylinders are numbered 1-3-5-7 on the driver side bank and 2-4-6-8 on the passenger side bank. Four cylinder inline engines are numbered 1-2-3-4 beginning on the <a href=\"https:\/\/www.carparts.com\/blog\/timing-belt\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"timing belt\">timing belt<\/a> end of the engine. This information is important but has little to do with a <a href=\"https:\/\/www.carparts.com\/blog\/p0300-code-random-or-multiple-cylinder-misfire-detected\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0300\">P0300<\/a>, which doesn&rsquo;t specify a particular cylinder.<\/p>\n\n\n\n<p>The firing order will also depend on the exact engine in your vehicle. The 2012 Dodge Grand Caravan firing order differs depending on the engine&rsquo;s size. The 2.4L has a firing order of 1-3-4-2, while the 3.0L has a 1-2-3-4-5-6 firing order. The 3.3L and the 3.8L engines meanwhile have a firing order of 1-2-3-4-5-6.<\/p>\n\n\n\n<p>But wait: How does the engine computer know which cylinder is misfiring anyway? Well, it works like this:<\/p>\n\n\n\n<p>To begin with, the PCM (Engine Computer) has to establish a baseline of how the Crankshaft Position Sensor pulses are spaced. This baseline snapshot is something the PCM learns and stores on its own, usually during deceleration, when the injectors are turned off and the engine is being driven by vehicle momentum through the transmission (coasting), because none of the cylinders are contributing power at that point. Without this information stored, the PCM cannot detect misfires. Technicians will use scan tool software to make the PCM learn this faster after they replace certain components or erase the PCM&rsquo;s memory.<\/p>\n\n\n\n<p>This baseline &ldquo;snapshot&rdquo; has different names among manufacturers. Chrysler refers to this piece of stored information as the &ldquo;Adaptive Numerator.&rdquo; GM and Ford refer to it as &ldquo;Crank Relearn&rdquo; or &ldquo;Case Relearn.&rdquo; One way or another, the PCM compares the live crankshaft pulses with the pattern it stored during the Crankshaft Learning process. The PCM typically updates this information periodically on its own as a part of the &ldquo;adaptive learning&rdquo; process PCMs use.<\/p>\n\n\n\n<p>The point of the &ldquo;Crankshaft Learn&rdquo; snapshot is that the PCM needs to know when the engine is misfiring, i.e., which cylinder isn&rsquo;t contributing, and it can tell by watching the crankshaft slow down every time a particular cylinder doesn&rsquo;t fire. It determines that by comparing the stored pattern with the live one. But there&rsquo;s another factor the PCM uses.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>The point of the &ldquo;Crankshaft Learn&rdquo; snapshot is that the PCM needs to know when the engine is misfiring, i.e., which cylinder isn&rsquo;t contributing, and it can tell by watching the crankshaft slow down every time a particular cylinder doesn&rsquo;t fire. It determines that by comparing the stored pattern with the live one.<\/p>\n<cite>&ndash;<a href=\"https:\/\/www.carparts.com\/blog\/author\/richardmccuistian\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Richard McCuistian, ASE Certified Master Automobile Technician\">Richard McCuistian, ASE Certified Master Automobile Technician<\/a><\/cite><\/blockquote>\n\n\n\n<p>Each piston travels up and down four times in a cycle, but each one only generates power on one of its four strokes. The crankshaft is able to maintain an even speed because every cylinder is contributing evenly its share when the engine is loaded. Again, if a cylinder isn&rsquo;t producing power, the crankshaft will very briefly slow down when it&rsquo;s that cylinder&rsquo;s turn to fire.<\/p>\n\n\n\n<p>So the crankshaft makes two full turns to complete a cycle and the camshaft only makes one full turn during a cycle because it spins at half crankshaft speed. For that reason, the PCM uses the <strong>Camshaft Position Sensor<\/strong> to identify which cylinder should be firing when the crankshaft slows down.<\/p>\n\n\n\n<p>The PCM measures how often a misfire happens within two different rpm windows to determine the frequency\/severity of a misfire. It stores misfires within a 200 rpm window of time and also within a 1000 rpm window of time. Obviously, a misfire that happens multiple times with a 200 rpm window is the most serious.<\/p>\n\n\n<style>.kadence-column10655_e68edc-ae > .kt-inside-inner-col,.kadence-column10655_e68edc-ae >

Combustion is a small explosion that takes place when a pressurized air-fuel mixture is ignited inside the combustion chamber above each piston. These explosions are timed very precisely for optimum power and efficiency. The combustion event superheats the inert nitrogen (which is 78 percent of the air charge) and the superheated nitrogen expands to drive the piston downward, which applies torque by way of the crankshaft to create the rotational force delivered to the transmission or transaxle, which then applies torque to the drive wheels.<\/p>\n\n\n\n    <div class=\"ai-summary-widget\">\n\n        <div class=\"ai-summary-grid\">\n\n            <div>\n                <div class=\"ai-avatar\">\n                    <figure>\n                        <img decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/q_auto,dpr_auto,f_auto\/carparts\/blog\/widgets\/ai-summary\/ai-bot\" alt=\"AI robot\">\n                    <\/figure>\n                    <span>ELI5<\/span>\n                <\/div>\n            <\/div>\n            <div>\n                <p>A misfire happens when one of the engine's cylinders doesn't create the small explosion it needs to work properly. This explosion, called combustion, happens when air and fuel mix together and get ignited inside the engine. The timing of these explosions is very important to make the engine work smoothly and efficiently. When the explosion happens, it heats up the air in the cylinder, making it expand and push the piston down. This pushing creates power that turns the crankshaft, which helps the car move.

This explosion, called combustion, happens when air and fuel mix together and get ignited inside the engine. The timing of these explosions is very important to make the engine work smoothly and efficiently. When the explosion happens, it heats up the air in the cylinder, making it expand and push the piston down. This pushing creates power that turns the crankshaft, which helps the car move. If there&rsquo;s a misfire, that explosion doesn&rsquo;t happen, and the engine doesn&rsquo;t get the power it needs.<\/p>\n\n\n\n<p>Code P0302 is part of a series of misfire DTCs that range from P0300 to <a href=\"https:\/\/www.carparts.com\/blog\/p0012-code-intake-a-camshaft-position-timing-over-retarded-bank-1\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0012\">P0012<\/a>. Each code between <a href=\"https:\/\/www.carparts.com\/blog\/error-code-p0301-cylinder-1-misfire-detected\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0301\">P0301<\/a> and P0312 indicates a misfire on a particular cylinder. For example, code P0301 indicates a misfire on cylinder one and code P0312 indicates a misfire on cylinder 12 (if your car has a 12-cylinder engine). Code P0300 is a bit different because it implies a &ldquo;random misfire&rdquo; rather than a misfire on a particular cylinder.<\/p>\n\n\n\n<p>Again, when there is a misfire, the crankshaft speed becomes slower than usual during the brief interval when the cylinder in question is supposed to be firing. The PCM continually monitors the crankshaft speed and notices any rpm loss that happens when a misfire occurs, even if it only happens once in a while, but misfires that happen a sufficient number of times within the 200 or 1000 rpm window (the ECM\/PCM keeps a running total) will store trouble codes. The device will set a P0302 code when it detects a frequent misfire on cylinder number 2.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Possible Causes of the P0302 Code?<\/h2>\n\n\n\n<p>There are many factors that can cause a cylinder 2 misfire&mdash;the most common of which are the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fuel delivery issues (e.g., a faulty fuel injector or damaged injector circuit)<\/li>\n\n\n\n<li>Ignition system problems (e.g., a failed coil pack or worn spark plug)<\/li>\n\n\n\n<li>Engine mechanical issues (e.g., a sticking valve or weak piston rings)<\/li>\n<\/ul>\n\n\n\n<p>It&rsquo;s worth noting that, if other misfire codes accompany a P0302, there will likely be more than one potential cause. Code P0302 by itself is a good indicator that the problem is with cylinder 2 only.<br>On the other hand, multiple misfire codes can indicate an issue, such as a vacuum leak or low fuel pressure, that affects various cylinders. Also, a consistent misfire on one cylinder will usually cause the ECM\/PCM to shut the injector down on that cylinder until the next start. It does this to protect the catalytic converter.<\/p>\n\n\n\n<p>To make diagnosis even more difficult, a cylinder 2 misfire can confuse the PCM and cause P0300 and other misfire codes to set.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Common Symptoms of the P0302 Code?<\/h2>\n\n\n\n<p>As previously mentioned, a P0302 may be accompanied by other codes, in which case you may observe symptoms that may not be mentioned here.
