Causes
- Faulty ignition coil (cylinder 2)
- Open/short in coil control wiring or connector
- Corroded/poor connector or pin contact at coil
- Faulty ignition coil driver in ECU
- Low battery or poor ground affecting coil driver
- Incorrect cam/crank sensor signals (timing/sync error)
Symptoms
- Check Engine Light (MIL) illuminated
- Rough idle or hesitation
- Misfire on cylinder 2 (felt or recorded)
- Reduced engine power and acceleration
- Increased fuel consumption and emissions
- Hard starting or stumble under load
What to check
- Read freeze frame and full trouble code list with a scan tool
- Check misfire counters / live data for cylinder 2
- Visually inspect coil 2 connector and wiring for damage, corrosion or pin damage
- Measure battery voltage and engine grounds
- Check related sensors: camshaft and crankshaft position sensor signals
- Swap coil 2 with another cylinder (if identical) to see if code follows coil
Signal parameters
- Expected coil primary resistance (typical range): ~0.3–2.0 Ω (varies by coil type)
- Expected coil secondary resistance (typical): ~5,000–15,000 Ω (varies)
- Coil driver voltage: pulsed 0–battery voltage (0–12 V) on primary circuit
- Dwell/pulse width: variable with RPM and load; typically a few ms at idle up to tens of ms under some conditions
- Oscilloscope waveform: clear sharp primary switching pulses and secondary high-voltage spike when cylinder fires
Diagnostic algorithm
- Retrieve P1367 and any related codes, note freeze-frame data (engine speed, load, temperature).
- Perform a visual inspection of coil 2, connector and wiring for damage, corrosion or loose pins. Repair obvious faults.
- Check battery voltage and engine ground integrity; poor supply can affect dwell. Repair as needed.
- Backprobe coil 2 primary while cranking/run: verify ECU is commanding coil (pulsed voltage) and measure pulse width with scope or DVOM. Compare to another cylinder.
- Measure coil 2 primary and secondary resistance; compare to manufacturer spec and to another coil. Replace coil if out of spec.
- Swap coil 2 with a known-good coil from another cylinder: if code/misfire moves, replace the coil. If not, continue.
- Check continuity between coil connector and ECU pin for opens/shorts; repair wiring or connector issues.
- Verify cam/crank sensor signals and timing/synchronization; repair sensors or timing if out of spec.
- If wiring and components are good and the ECU driver is suspected, test for driver faults (specialist bench/ECU testing) or consult dealer for ECU diagnosis/software updates.
- After repairs, clear codes and road-test while monitoring live data to confirm the fault does not return.
Likely causes
- Defective coil pack or single coil serving cylinder 2
- Damaged/shorted coil primary wiring between coil and ECU
- Loose or corroded connector at ignition coil 2
- ECU driver transistor failure for coil 2
- Intermittent supply/ground fault reducing coil dwell time
Fault status
Status
P1367 - Ignition coil 2 control / spark time fault. Possible coil circuit, timing or ECU driver issue affecting cylinder 2.
