Dodge Code P2320 is a diagnostic monitor used to ensure that each coil-on-plug ignition coil has achieved a sufficient burn. It is essential to correctly diagnose and resolve this code, as any fault can lead to an inefficient running engine or even an engine that will not start. P2320 is a common code for Dodge vehicles and is triggered when the powertrain control module (PCM) is unable to complete the ground circuit (low-side driver) allowing the energy to build the magnetic field of the primary coil. In this article, I will discuss the causes and solutions associated with Dodge Code P2320.

Causes and Solutions of Dodge Code P2320
| Cause | Solution |
|---|---|
| Fused ASD Relay Output Circuit Open or High Resistance | Verify the integrity of the ASD Relay Output Circuit with a digital multimeter. |
| Coil 7 Control Circuit Shorted to Ground | Use a digital multimeter to check for a short to ground in the Coil 7 Control Circuit. |
| Coil 7 Control Circuit Open or High Resistance | Use a digital multimeter to check the Coil 7 Control Circuit for continuity and resistance. |
| Spark Plug | Replace the spark plug and verify that it is the correct type. |
Fused ASD Relay Output Circuit Open or High Resistance
A faulty or open ASD Relay Output Circuit might trigger a Dodge Code P2320. The ASD Relay Output Circuit sends power to the coil-on-plug ignition coils. A fault in this circuit can result in an inefficient running engine or even an engine that will not start. To diagnose this issue, a technician must use a digital multimeter to verify the integrity of the ASD Relay Output Circuit.
Coil 7 Control Circuit Shorted to Ground
The Coil 7 Control Circuit sends the signal to the coil-on-plug ignition coil. A short to ground in this circuit can cause the Dodge Code P2320 to be triggered. To diagnose this issue, a technician must use a digital multimeter to check for a short to ground in the Coil 7 Control Circuit.

Coil 7 Control Circuit Open or High Resistance
Open or high resistance in the Coil 7 Control Circuit can also cause the Dodge Code P2320 to be triggered. To diagnose this issue, a technician must use a digital multimeter to check the Coil 7 Control Circuit for continuity and resistance.
Spark Plug
A faulty, worn, or incorrect spark plug can trigger the Dodge Code P2320. The spark plug must be replaced with the correct type to fix this issue.

Conclusion
In conclusion, Dodge Code P2320 is a common code for Dodge vehicles. It is triggered when the powertrain control module (PCM) cannot complete the ground circuit (low-side driver), allowing the energy to build the magnetic field of the primary coil. The most common causes and solutions of Dodge Code P2320 include a fault in the ASD Relay Output Circuit, a short to ground in the Coil 7 Control Circuit, high resistance in the Coil 7 Control Circuit, and a faulty, worn, or incorrect spark plug. A technician must use a digital multimeter to diagnose and resolve this code.
