Jeep owners who encounter the code P2302 may be feeling a bit overwhelmed. This code indicates an issue with the ignition coil 1 secondary circuit, which is responsible for creating a spark that powers the engine. The Powertrain Control Module (PCM) manages the process of creating this spark, and when it is not working correctly, the Jeep code P2302 is registered. This issue has several potential causes, ranging from a faulty Fused Automatic shutdown (ASD) Relay Output circuit to a problem with the Powertrain Control Module (PCM) itself.

| Spark Plug | Replace the spark plug if it is worn, damaged, or corrupted. |
| Coil on Plug | Replace the Coil on the Plug if it is damaged or corrupted. |
| Powertrain Control Module (PCM) | Replace the PCM if it is damaged or corrupted. |
Jeep owners who experience the code P2302 may be concerned about the issue, as it can lead to engine misfires, poor fuel economy, or even engine stalling. To ensure that the Jeep is running correctly and that the code is not generated, it is important to understand the potential causes and possible solutions. The Fused Automatic Shut Down (ASD) Relay Output circuit, Coil Control 1 Circuit, Spark Plug, Coil on Plug, and Powertrain Control Module (PCM) can all be potential causes of the code P2302, and all should be tested to ensure that they are functioning correctly. Once the cause is identified, the necessary repairs can be made to return the Jeep to optimum performance.
Fused ASD Relay Output Circuit Open or High Resistance
The Fused Automatic Shutdown (ASD) Relay Output circuit provides power to the spark plugs. If the course is open or has a high resistance, then the spark plugs may not be able to produce the necessary spark to power the engine. To diagnose this issue, the wiring and connections should be checked for any signs of damage or corrosion, and the voltage should be tested to ensure that it is within the normal range. If the wiring or connections are damaged, they should be repaired or replaced.
Coil Control 1 Circuit Shorted to Ground
The Coil Control 1 Circuit signals the spark plugs to fire. If this circuit is shorted to ground, the spark plugs will not be able to produce the necessary spark to power the engine. To diagnose this issue, the wiring and connections should be checked for any signs of damage or corrosion, and the Coil Control 1 Circuit should be inspected for any signs of wear. If the wiring or connections are damaged, they should be repaired or replaced.
Coil Control 1 Circuit Open or High Resistance
The Coil Control 1 Circuit signals the spark plugs to fire. If this circuit is open or has a high resistance, then the spark plugs will not be able to produce the necessary spark to power the engine. To diagnose this issue, the wiring and connections should be checked for any signs of damage or corrosion, and the Coil Control 1 Circuit should be inspected for any signs of wear. If the wiring or connections are damaged, they should be repaired or replaced.

Spark Plug
The spark plug is responsible for creating a spark that powers the engine. If the spark plug is worn, damaged, or corrupted, the engine may not be able to produce the necessary spark to power the machine. To diagnose this issue, the spark plug should be inspected for any signs of wear or damage and replaced if necessary.
Coil on Plug
The Coil on the Plug creates a spark that powers the engine. If the Coil on the Plug is damaged or corrupted, the engine may not be able to produce the necessary spark to power the machine. The Coil on the Plug should be inspected for any signs of wear or damage and replaced if required to diagnose this issue.
Powertrain Control Module (PCM)
The Powertrain Control Module (PCM) is responsible for managing the process of creating the spark that powers the engine. If the PCM is damaged or corrupted, the engine may not be able to produce the necessary spark to power the machine. To diagnose this issue, the PCM should be inspected for any signs of wear or damage and replaced if necessary.
