Error Code P0350: What It Means & What To Do?

<<See All OBD Codes

The most common ways to note the problematic ignition coil circuit is the Check Engine light illuminating. Also, another major hint can be the ignition misfires that are resulting in improper combustion of the air to fuel mixture in the engine. This problem can be indicative of OBD code P0350 that can get stored in the PCM and is flashed in the system

The ignition system converts battery voltage into the high voltage used to ignite the cylinder air/fuel mixture. The low voltage side of the system is referred to as the primary circuit. It includes the battery, ignition switch, primary coil winding, a triggering mechanism (such as a crankshaft sensor) and switching device (such as an ignition module or ECU). The high voltage side of the system is called the secondary circuit. On modern vehicles it includes the coil pack and spark plugs.

P0350 code pertains to the electrical circuitry between the PCM and the individual (or multiple) ignition coils, as well as the coils themselves. Typical designs provide a switched supply of battery voltage to the ignition coil, with a pulsing ground (supplied by the PCM) to activate ignition spark and control ignition timing. Variations in ignition coil circuit voltage that differ by greater than 10-percent from the manufacturer’s reference voltage will cause a code to be stored and a service engine soon lamp to be illuminated.

What causes this problem with the Ignition Coil Primary/Secondary Circuit Malfunction?

• Open or shorted primary/secondary circuits
• Defective ignition coils or coil pack/s
• Bad ignition system relay
• Blown fuses or fusible links
• Faulty PCM or a PCM programming error

1. Engine Control Module - OBD Error Code P0350 can also be due to faulty ECMs. This may lead to engine stalling or not starting, and check engine lights being on. It’s better to get the faulty electricals replaced as soon as possible.
2. Powertrain Control Module - P0350 error code also relates to problems with the powertrain that is not able to generate response in time causing distorted engine timing. Find all the Powertrain related parts with us.
3. Diagnostic Tool - Choose from our wide variety of diagnostic tools to detect and correct the OBD code error.
4. Ignition Coil - Check if the ignition coils are faulty and if hampering the ignition system and replace as required.
5. Ignition Relay - Is the ignition relay working properly? If not, buy new parts and replace old faulty parts now!
6. Engine Wiring Harness - Check for damaged wiring harness and replace it now! Buy new components form us.
7. Fuel Sender Connector - Always inspect for faulty connectors that might pose hindrance to the performance. Replace faulty connector now!
8. Battery & Electrical System - Buy quality battery and electrical components and replace the old ones, if found faulty. Buy from us now!
9. Diagnostic Tools - Use professional level tools to

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0350 here:

Common Symptoms

• Decreased engine performance
• Increased fuel consumption
• Ignition misfires
• Engine stalling and not starting

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• If any components related to the ignition coil system (including the PCM) have been identified as faulty, they should be repaired or replaced as is needed.
• If there is an issue with the wiring or connectors, the circuit between the PCM and affected ignition coil should be reconnected or replaced as necessary. The ignition system should be retested after each individual repair in order to identify the source of the problem.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Ignition Coil, PCM, ECM, Ignition System Relay, Fuses, Fusible Links, Engine, Wiring, Connectors, Fuel and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Special attention should be placed on the circuits between the PCM and ignition coils, as well as the ignition coils themselves.
• Disconnected ignition coils may be identified by shaking them gently by hand and seeing if they budge.
• A P0350 is often caused by a problem with the electrical circuit. The wiring and electrical connectors should be thoroughly inspected.
• If the ignition coils and wiring have both checked out, the possibility of a faulty PCM may be considered.

Common Mistakes When Diagnosing the P0350 Code

Always check for all the components for faults before directly jumping to the ignition coils for the diagnosis. Check for the following components as well:

• Ignition relay failure
• Powertrain Control Module (PCM) failure
• Wiring issue
