When the Jeep P2305 code is encountered, it is essential to understand what it means in order to quickly diagnose the issue and find the solution. This code is an indication that the ignition coil 2 secondary circuit has insufficient ionization. Ignition coils are supplied with 12 volts from the Fused Automatic Shut Down (ASD) Relay Output circuit. The Powertrain Control Module (PCM) completes the ground circuit, allowing energy to build the magnetic field of the primary coil. The PCM will open the low side driver to allow the magnetic field to collapse to the secondary winding and be transferred to the spark plug.
Causes and Solutions for Jeep P2305 Code
| Cause | Solution |
|---|---|
| Fused ASD Relay Output Circuit Open or High Resistance | Check the circuit for any open or high resistance. |
| Coil Control 2 Circuit Shorted to Ground | Replace the circuit for a new one. |
| Coil Control 2 Circuit Open or High Resistance | Replace the circuit with a new one. |
| Spark Plug | Clean and replace the spark plug. |
| Coil on Plug | Replace the Coil on Plug. |
| Powertrain Control Module (PCM) | Replace the PCM. |
When a Jeep P2305 code is encountered, it indicates that the ignition coil 2 secondary circuit has insufficient ionization. This code is triggered when the Powertrain Control Module (PCM) does not detect a sufficient burn from the ignition coil. It is important to understand the cause of the issue in order to properly diagnose the problem and come up with a solution. It is likely that the problem is caused by the Fused Automatic Shut Down (ASD) Relay Output circuit, the Coil Control 2 Circuit, the spark plug, the Coil on Plug, or the Powertrain Control Module (PCM). Depending on the cause, the solution can range from checking the circuit for any open or high resistance, replacing the circuit with a new one, cleaning and replacing the spark plug, replacing the Coil on Plug, or replacing the PCM.
Checking the Fused ASD Relay Output Circuit
When the Fused ASD Relay Output Circuit is the cause of the Jeep P2305 code, the solution is to check the circuit for any open or high resistance. If the circuit is open or high resistance, it needs to be replaced with a new one. This can be done by a qualified mechanic or automotive expert.
Replacing the Coil Control 2 Circuit
If the Coil Control 2 Circuit is the cause of the Jeep P2305 code, the solution is to replace the circuit with a new one. This can be done by a qualified mechanic or automotive expert.
Cleaning and Replacing the Spark Plug
When the spark plug is the cause of the Jeep P2305 code, the solution is to clean and replace the spark plug. This can be done by a qualified mechanic or automotive expert.
Replacing the Coil on Plug
If the Coil on Plug is the cause of the Jeep P2305 code, the solution is to replace the Coil on Plug. This can be done by a qualified mechanic or automotive expert.
Replacing the Powertrain Control Module (PCM)
When the Powertrain Control Module (PCM) is the cause of the Jeep P2305 code, the solution is to replace the PCM. This can be done by a qualified mechanic or automotive expert.
Conclusion
When a Jeep P2305 code is encountered, it is important to understand the cause of the issue in order to properly diagnose the problem and come up with a solution. Depending on the cause, the solution can range from checking the circuit for any open or high resistance, replacing the circuit with a new one, cleaning and replacing the spark plug, replacing the Coil on Plug, or replacing the PCM. It is recommended to seek the help of a qualified mechanic or automotive expert to properly diagnose and fix the Jeep P2305 Code.
