Troubleshooting Ignition Coil 3 Secondary Circuit Insufficient Ionization – P2308 Error Code

FAQ & Answers

Q: What are the symptoms of Ignition Coil 3 Secondary Circuit- Insufficient Ionization?
A: The symptoms of Ignition Coil 3 Secondary Circuit- Insufficient Ionization are Ignition Coil 3 Fails to Activate and Poor Engine Performance.

Q: How can I diagnose this problem?
A: To diagnose this problem you should check the Secondary Circuit of COIL-3 for Electrical Resistance and Current Flow and inspect Spark Plug for Corrosion and Electrode Erosion.

Q: What is the repair procedure for this problem?
A: The repair procedure for this problem would include replacing the Spark plus Wire, Ignition Coil and Capacitor from the Ignition Coil Secondary Circuit, re-adjusting the Secondary Circuit Setting and installing new components to reset configuration for COIL-3.

Q: How can I check if my repairs were successful?
A: To check if your repairs were successful you should conduct a Voltage Drop Test on components in the Secondary Circuit of COIL-3 and inspect continuity of Pin Connectors in Socket or Wiring Harness Connectors connected to ECU.

Q: What tools do I need when troubleshooting this issue?
A: When troubleshooting this issue you should utilize an Oscilloscope to diagnose Ignition Performance Pattern Analysis of COIL-3, use a Digital MultiMeter to measure the current flow through the Coil Pack for Insufficient Ionization, use an Air Pressure Gauge in order to measure pressure levels within Fuel System/Injectors/Intake Manifold, and inject Carbon Dioxide into hoses to remove any blockage.

The P2308 diagnostic trouble code indicates that there is an issue with the ignition coil 3 secondary circuit, most likely due to insufficient ionization. To fix the problem, it is recommended to replace the faulty ignition coil and check the spark plugs and wiring harness for any damage or corrosion. This should help to restore proper ionization in the secondary circuit of the ignition coil 3 and ensure proper engine function.
