2022年6月16日 · What are the possible causes of OBDII code P0351 in a Chevrolet indicating an issue with Ignition Coil 1? - Possible causes include a faulty ignition coil, damaged wiring or connectors, a defective PCM, or issues with the ignition system.

2020年5月12日 · P0351 is a generic OBD II trouble code. it indicates that ignition coil "A" is malfunctioning. It is typically caused by a bad coil pack or wiring harness issue. The primary wiring is the wiring harness leading from the PCM to the ignition system itself.

2008年2月28日 · Each ignition coil has the following circuits: Sequencing and timing are PCM controlled. If the PCM detects that the IC circuit is out of range, DTC P0351-P0358 sets. The engine is operating. The PCM detects the IC circuit is grounded, open, or shorted to voltage for less than 1 second .

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.

What Is Code P0351? 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).

2024年12月4日 · The P0351 is an OBD-II Trouble Code that stands for “Ignition Coil” A” Primary/Secondary Circuit Malfunction and is triggered when the ignition coil on cylinder #1 is not working properly. The vehicle’s ignition coil consists of …

What Does the P0351 Code Mean? The P0351 code indicates that the powertrain control module (PCM) detects an issue with the cylinder #1 ignition coil or its circuit. The ignition coil works like a transformer. It contains two coils.

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

OBD2 Code P0351 GM definition: The COP (coil on plug) ignition system is what is used on most modern engines. There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module). It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Two wires are dedicated to each coil.

2017年1月26日 · The PCM sets an ignition coil control circuit code P0351-P0358 when it detects a problem with the ignition coil circuit. The last digit of these codes references the cylinder where the issue is occurring. For example, P0351 indicates a fault in the #1 cylinder coil circuit. Likewise, P0358 indicates a problem with the coil circuit on cylinder #8.
