Causes
- Open or short in ignition coil 2 wiring (primary or trigger circuit)
- Faulty ignition coil 2 (coil pack or individual coil)
- Poor connector connection or corrosion at coil 2
- Faulty ECU ignition driver for coil 2
- Incorrect camshaft or crankshaft position signal (timing/synchronisation issue)
- Software/calibration error or intermittent ECU fault
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Rough idle or vibration
- Misfire felt at low speed or under load (possible cylinder 2 misfire)
- Reduced engine power and poor acceleration
- Difficulty starting or intermittent no-start
What to check
- Read stored DTC(s) and freeze-frame data with a diagnostic scanner
- Check for related codes (misfire, cam/crank sensor, coil driver codes)
- Visual inspection of coil 2 connector, wiring harness and grounding points
- Measure coil primary resistance and compare with spec
- Check supply voltage and ground at coil connector with key on/engine cranking
- Use oscilloscope to view coil primary trigger waveform and dwell time
Signal parameters
- Coil primary voltage: ~0–12 V pulses (depends on vehicle circuit)
- Dwell/charge time: typically 1–5 ms (manufacturer-specific)
- Trigger frequency: synchronized to ignition timing and engine speed
- Secondary voltage: high-voltage pulse required to fire spark (kV range)
- Cam/crank position signals: square/sinusoidal reference pulses used for timing
Diagnostic algorithm
- Connect a compatible scan tool, record P1367 and any related codes, note freeze-frame data (RPM, load, temp).
- Perform a visual inspection of ignition coil 2 connector and wiring for damage, corrosion or loose pins.
- With ignition off, unplug coil 2 connector and check for proper battery voltage on the supply pin and good ground continuity to chassis/ECU.
- Measure coil 2 primary resistance and compare to manufacturer specification; if out of spec, replace coil.
- If resistance is normal, use an oscilloscope or lab scope to monitor the coil primary waveform while cranking/running; look for missing/abnormal pulses, incorrect dwell or noisy signal.
- Swap coil 2 with another cylinder’s coil (if coils are identical) and clear codes; if fault follows the coil, replace it. If fault stays on cylinder 2, investigate wiring/ECU.
- Check camshaft and crankshaft position sensor signals and timing (timing chain/belt condition, sensor alignment). An incorrect timing reference can cause spark timing faults.
- If wiring and sensors are good but fault persists, inspect ECU ignition driver outputs and related fuses/relays; consider ECU bench testing or replacement as a last resort.
- After repairs, clear codes and road-test. Re-scan to confirm P1367 does not return under conditions that previously set the code.
Likely causes
- Damaged wiring or poor connector to ignition coil 2
- Defective ignition coil 2
- Faulty camshaft/crankshaft position sensor or timing belt/chain jumped
- Failed ECU ignition driver (less common)
