When a Subaru vehicle presents code P0353, this is a warning that something is wrong with the Ignition Coil C Primary/Secondary Circuit. The code is associated with improper idling and poor driving performance, and it can be caused by several different issues. Understanding the causes of code P0353 is essential for diagnosing and addressing the problem. Many of the causes of this code are related to the electrical components of the vehicle, such as open circuits, short circuits, faulty relays, and blown fuses. Other causes can include poor spark plug condition and faulty ECM connections. In order to properly diagnose the issue, it is important to understand the potential causes and solutions for this code. This article will provide an overview of the causes and solutions related to Subaru P0353 Code.
Causes and Solutions for Subaru P0353 Code
| Cause | Solution |
|---|---|
| Open circuit or short circuit to ground in harness of power supply circuit | Inspect the connectors and check for continuity in the circuit |
| Blown out of fuse | Replace the fuse |
| Poor contact of IG relay connector | Clean and reconnect the connector |
| Poor contact of coupling connector | Clean and reconnect the connector |
| Faulty IG relay | Replace the relay |
| Poor spark plug condition | Replace the spark plugs |
| Open circuit between ignition coil connector and engine grounding terminal | Inspect and repair the circuit |
| Ground short circuit of harness between ECM connector and ignition coil connector | Repair the short circuit |
| Faulty ignition coil | Replace the ignition coil |
| Faulty ECM connection | Replace the ECM connection |
When a Subaru vehicle displays code P0353, it is important to understand the potential causes and solutions. As this code is associated with the Ignition Coil C Primary/Secondary Circuit, it can be caused by several electrical issues, such as open circuits, short circuits, and blown fuses. Other causes can include poor spark plug condition and faulty ECM connections. To diagnose the issue, it is essential to understand the potential causes and solutions for Subaru P0353 Code. In this article, we have outlined the causes and solutions related to this code.
Open Circuits and Short Circuits
When a Subaru vehicle presents code P0353, it is likely due to an open circuit or short circuit to ground in the power supply circuit’s harness. To properly diagnose and address this issue, it is important to inspect the connectors in the circuit and check for continuity. If a short circuit or open circuit is found, it should be repaired as soon as possible in order to prevent further damage to the vehicle.
Blown Fuses
Another potential cause of Subaru P0353 Code is a blown fuse. If the fuse is blown, it must be replaced in order to restore proper operation of the Ignition Coil C Primary/Secondary Circuit. It is important to replace the fuse with a new one of the same rating in order to prevent any further issues.
Faulty Connectors
In some cases, the code may be caused by poor contact of the IG relay connector or the coupling connector. In this case, it is important to clean and reconnect the connectors in order to restore proper operation. If this does not solve the issue, it is possible that the IG relay or the coupling connector is faulty and must be replaced.
Spark Plugs and ECM Connections
Other potential causes of code P0353 can include poor spark plug condition and faulty ECM connections. If the spark plugs are in poor condition, they should be replaced in order to restore proper operation of the Ignition Coil C Primary/Secondary Circuit. Additionally, if the ECM connection is faulty, it should be replaced in order to prevent further issues.
Conclusion
When a Subaru vehicle presents code P0353, it is essential to understand the potential causes and solutions in order to properly diagnose and address the issue. This code is associated with improper idling and poor driving performance, and it can be caused by several different issues, such as open circuits, short circuits, blown fuses, poor spark plug condition, and faulty ECM connections. By understanding the causes and solutions of Subaru P0353 Code, it is possible to diagnose and repair the issue quickly and efficiently.
