P0353 is a diagnostic trouble code (DTC) for "Ignition Coil C Primary/Secondary Circuit Malfunction". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
The P0353 code is a generic powertrain code related to the ignition system or an engine misfire. In this case, a malfunction has been found specifically in ignition coil C (or number 3) in the primary or secondary circuit. Codes related to the P0353 include:
Currently, most vehicles equipped with an OBD-II use a coil-on-plug system for an ignition spark. Frequently, most vehicles with an OBD-II system use an ignition system with an individual coil for each cylinder. Each coil is often secured by the spark plugs. Controlled by the engine control module (ECM), each ignition coil is connected to the engine and uses a small spark plug wire or boot which insulates the high-voltage spark between the spark plug and coil.
A switched supply of battery voltage is provided to the ignition coil. A pulsing ground is supplied by the ECM, which activates the ignition spark and controls the ignition timing. If the voltage in the ignition control circuit for ignition coil C varies by more than 10% from allowed parameters, set by each automaker, a malfunction is noted and a P0353 code is stored.
Several problems may cause a P0353 code including:
Symptoms of a P0353 code may include:
A mechanic may use several methods to diagnose a P0353 trouble code, including:
Because there is a possibility a P0353 code can be stored due to a faulty ECM, be sure to completely diagnose any possible wiring faults or issues before diagnosing the ECM as the cause.
Because a vehicle’s safe driving operation will not likely be impacted due to faults that store a P2090 code, this code is not considered a potentially serious code. However, when this code appears, it is recommended to take your vehicle to your local service center or mechanic for repair and diagnosis as soon as possible.
Several repairs can fix a P0353 trouble code and include:
Some OBD-II systems will disable the fuel injector on the cylinder that is being impacted when a P0353 code is stored. Often, other codes related to the injector circuit or engine misfires will show up in a scan.
In addition, even though this code calls out a specific ignition coil, checking to ensure all coils are firmly in place and show no signs of damage is recommended.
