The P0351 code for Chevrolet vehicles indicates a problem with the ignition coil 1 control circuit. The ignition coil is a crucial component of the ignition system, responsible for generating the high voltage needed to ignite the fuel mixture in the engine cylinders.

The P0351 code indicates “Ignition Coil “A” Primary/Secondary Circuit Malfunction.” The ignition coil of your vehicle contains a “ primary ” winding and a “ secondary ” winding. A switching device is used to trigger the primary winding so that the secondary winding generates the …

2020年5月13日 · P0351 is a generic OBD II trouble code, which means that it means the same thing for the Chevy Silverado as it would any other vehicle. It indicates that ignition coil "A" is malfunctioning. It is typically caused by a bad coil pack or wiring harness issue, although there can be other causes as well.

2022年6月16日 · Code P0351 Chevrolet Description. The ignition system on this engine uses ignition coils with integrated power transistors. The Engine Control Module (ECM) controls the spark event for each cylinder through individual ignition coil control circuits.

Code P0351 is defined as “Ignition Coil ‘A’ Primary/Secondary Circuit Malfunction.” It’s an OBD-II diagnostic trouble code (DTC) that indicates a fault with ignition coil ‘A’ (a problem with the coil on cylinder #1 or its circuit). The P0351 code is a generic DTC — meaning it indicates the same issue for any vehicle that ...

Potential causes of a P0351 code include: Is the engine misfiring presently? If not, the problem is likely intermittent. Try wiggle testing the wiring at the #1 coil and along the wiring harness to the PCM. If manipulating the wiring causes the misfire to surface, repair the wiring problem. Check for poor connection at the coil connector.

2021年6月23日 · The P0351 code stands for “Ignition Coil ‘A’ Primary/Secondary Circuit.” It indicates a potential problem with cylinder #1 ignition coil or its circuit. Some possible causes include a faulty ignition coil, issues with the ignition coil circuit, or a problem with the PCM.

The P0351 diagnostic trouble code (DTC) indicates a problem with the ignition coil 1 control circuit. The ignition coil is a crucial component of the ignition system, responsible for converting the low voltage from the battery into the high voltage needed to ignite the air-fuel mixture in the engine cylinders.

Code P0351 indicates there's an electrical problem in either the primary ( the computer side ) or the secondary ( the spark plug side ) of the Ignition Coil "A" Circuit. P0351 Symptoms. Check Engine Light will illuminate; Engine idles rough; Engine misfires on acceleration; In rare cases, the engine may not exhibit noticeable symptoms

2017年1月26日 · Current is applied to the primary side of the coil, which creates a magnetic field around the winding. Then, the current is interrupted by a switching device (usually the PCM). This causes the magnetic field to collapse, inducing a voltage into the winding. Simultaneously, the collapsing magnetic field creates a voltage in the secondary winding.
