Diagnostic Procedure
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
DIAGNOSIS PROCEDURE - P2302-IGNITION COIL #1 SECONDARY CIRCUIT-INSUFFICIENT IONIZATION (2.0L/2.4L);
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Ignition on, engine not running. With the DRBIII®, read DTCs and record the related Freeze Frame data. Is the Good Trip Counter displayed and equal to zero? Yes --> Go To 2 No --> Go To 9 |
All |
| 2 |
NOTE:
This test must be repeated for the adjacent ignition wire. Turn the ignition off.Disconnect the ignition wire from the spark plug.
NOTE:
Before continuing inspect the ignition wire for damage or carbon tracking coil or the spark plug insulator boot. If a problem is found, replace the ignition wire. Install a spark tester to the ignition wire.While cranking the engine observe the spark coming from the spark tester.
NOTE:
A crisp blue spark that is able to jumper the gap of the spark tester should be generated. Is a good spark generated?Yes --> Ensure the cylinder is operating properly. If OK, replace the Spark Plug.Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC .No --> Go To 3 |
All |
| 3 |
NOTE:
This test must be repeated for the adjacent ignition wire. Turn the ignition off.Remove the ignition wire.Measure the resistance of the ignition wire.Is the resistance below 10K ohms?Yes --> Go To 4No --> Replace the Ignition Wire.Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
All |
| 4 | Turn the ignition off. Disconnect the Ignition Coil harness connector. Turn the ignition on. With the DRBIII®, actuate the ASD Relay. Using a 12-volt test light connected to ground, probe the (A142) ASD Relay Output circuit in the Ignition Coil harness connector. Does the test light illuminate brightly? Yes --> Go To 5 No --> Repair the (A142) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
All |
| 5 | Turn the ignition off. Disconnect the Ignition Coil harness connector. Using a 12-volt test light connected to 12-volts, probe the Ignition Coil Control circuit. Crank the engine for 5 second while observing the test light. Does the test light blink/flicker? Yes --> Replace the Ignition Coil. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . No --> Go To 6 |
All |
| 6 | Turn the ignition off. Disconnect the Ignition Coil harness connector. Disconnect the PCM harness connector. Measure the resistance of the Coil Control circuit between the Ignition Coil harness connector and the special tool #8815 terminal. Is the resistance below 5.0 ohms? Yes --> Go To 7 No --> Repair the Coil Control circuit for an open. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
All |
| 7 | Turn the ignition off. Disconnect the Ignition Coil harness connector. Disconnect the PCM harness connector. Measure the resistance between ground and the Coil Control circuit in the Ignition Coil harness connector. Is the resistance below 100k ohms? Yes --> Repair the Coil Control circuit for a short to ground. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . No --> Go To 8 |
All |
| 8 |
NOTE:
Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary. If there are no possible causes remaining, view repair.RepairReplace and program the Powertrain Control Module in accordance with the Service Information.Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
All |
| 9 | Turn the ignition off. Remove the Spark Plug. Inspect the Spark Plug for the following conditions.
NOTE:
Lightly tap the bottom of the spark plug on a solid surface. The electrode in the spark plug should not move. Were any of the above condition present? Yes --> Replace the Spark Plug. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . No --> Refer to the INTERMITTENT CONDITION . Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
