Damaged or shorted ignition coil for cylinder 2
Chafed, pinched or shorted wiring harness to coil #2 (short to ground or to another circuit)
Corroded or loose connector at the coil or ignition module
Faulty spark plug or plug wire causing leakage/short
Faulty PCM/ECM ignition driver (less common)
Aftermarket or incorrect ignition component with wrong specifications

Read freeze frame and misfire counters with a scan tool to confirm cylinder 2 involvement
Visual inspection of ignition coil, spark plug, plug boot and wiring for damage, oil or corrosion
Check coil connector for bent pins, corrosion, secure fit
Wiggle test wiring while engine is running (observe live misfire data) to find intermittent shorts
Swap coil #2 with another cylinder's coil; if code follows coil, coil is likely faulty
Measure supply voltage and ground at the coil connector with key on/engine cranking

Primary coil resistance (typical range): low ohms — check factory spec (commonly ~0.2–2 Ω)
Secondary coil resistance (typical range): kilo-ohm range — check factory spec (commonly ~5–15 kΩ)
Connector supply voltage: battery voltage (~11–14 V with engine running) on coil supply pin
Primary waveform: square/dwell pulses on primary (~0–12 V) when cranking/engine running — use scope to compare to known-good
Expected behavior: no continuity from coil primary or secondary to ground except through specified coil windings

Retrieve freeze frame and confirm P1352 is current and cylinder 2 misfire is present. Clear codes and perform a road or engine run test to re-check.
Perform a visual inspection of ignition coil #2, spark plug and boot for carbon tracking, oil, cracks or fouling. Repair/replace obvious damaged parts.
Inspect the wiring harness and connector for cuts, pinched sections, melted insulation, or corrosion. Repair any damaged wiring or connector pins.
With ignition off, unplug coil #2 and visually inspect pins. Measure connector supply (key on) for battery voltage and measure continuity to ground where appropriate.
Swap coil #2 with another cylinder’s coil (or swap coil harness connectors) and rerun. If the fault moves to the other cylinder, replace the coil.
Measure primary and secondary coil resistances and compare to factory specifications. Replace coil if out of spec or shows short to ground.
Use an oscilloscope on the coil primary to look for abnormal waveforms, collapsed primary, or evidence of shorting during operation.
Check for continuity between coil primary/secondary circuits and ground or other circuits (shorts). Repair wiring short to ground or other circuits as found.
After repairs, clear codes and verify repair with drive cycle and confirm no reoccurrence. If all wiring and coil are good and code persists, suspect PCM/ignition driver and verify with manufacturer procedures before replacement.
