AI status
Completed
Completed
100%
Causes
- Faulty ignition coil on cylinder 6
- Worn or fouled spark plug in cylinder 6
- Faulty or clogged fuel injector for cylinder 6
- Low compression or mechanical damage (valve, piston, head gasket) on cylinder 6
- Wiring or connector fault to coil/injector on cylinder 6
- Low battery/insufficient cranking voltage
Symptoms
- SES/MIL (check engine light) illuminated at/after start
- Engine cranks but struggles to start or fires unevenly
- Rough/cranky idle immediately after start (may clear after warming)
- Reduced engine power right after start
- Possible visible uneven exhaust smoke or smell of unburnt fuel at startup
- Stored freeze-frame data showing misfire count on cylinder 6 during cranking
What to check
- Retrieve stored and pending codes and freeze-frame data (note battery voltage and load at time of event)
- Use live data to check cylinder contribution and misfire counters during a cranked start attempt
- Confirm battery voltage during cranking (should be >9.5V for most tests)
- Visually inspect ignition coil, boot, and spark plug for carbon tracking, oil, or damage
- Inspect coil and injector harnesses and connectors for corrosion, broken wires, or loose pins
- Perform a coil swap: move cylinder 6 coil to another cylinder and re-test to see if misfire follows the coil
Signal parameters
- Cranking battery voltage (V)
- Cylinder 6 misfire counter / cylinder contribution (%)
- Crankshaft and camshaft position correlation during cranking (°)
- Injector pulse width for cylinder 6 during cranking (ms)
- Ignition coil primary voltage and dwell, secondary waveform and spark signature
- Fuel rail pressure (bar/psi) at cranking
Diagnostic algorithm
- Connect scan tool, read MIL codes and freeze-frame; record battery voltage and conditions at event
- Attempt to reproduce: monitor misfire counters and engine data during a controlled start attempt
- Check battery state and starter cranking speed; confirm adequate voltage under load
- Visually inspect coil, plug, injector and wiring on cylinder 6 for damage or contamination
- Swap coil from cylinder 6 with another cylinder; if misfire follows coil, replace coil
- If coil swap does not move the fault, swap the injector; if misfire follows injector, service/replace injector
- Check spark plug condition and gap; replace plug if fouled or worn
- Perform compression test or leak-down test on cylinder 6 to rule out mechanical failure
- If mechanical is good, scope coil and injector signals during cranking to confirm proper timing and amplitude
- Verify fuel rail pressure and injector pulse width during cranking; correct fuel delivery issues if present
- Inspect cam/crank sensor signals and timing (VANOS/chain condition) if synchronization error suspected
- Repair identified faulty component, clear codes and perform repeated start cycles to confirm repair; advise further mechanical repair if compression/test indicates damage
Likely causes
- Failed ignition coil pack/module for cylinder 6
- Carbon-fouled or damaged spark plug in cylinder 6
- Injector stuck open/partial or electrically intermittent for cylinder 6
- Open/short in coil or injector harness for cylinder 6 or poor connector pin contact
- Low compression on cylinder 6 due to burnt valve, head gasket leak at that cylinder, or piston damage
- Weak battery or poor starter causing slow cranking and weak spark
Fault status
Status
Control module detected a misfire event on cylinder 6 during engine start/cranking and stored code P1352. Freeze-frame and misfire counters were recorded when the start misfire threshold was met. Code may be pending or confirmed depending on occurrence frequency.
Repair difficulty: Medium
Diagnostic time: 1.5 - 3.0 hours

Causes
- Faulty ignition coil on cylinder 6
- Worn or fouled spark plug in cylinder 6
- Faulty or clogged fuel injector for cylinder 6
- Low compression or mechanical damage (valve, piston, head gasket) on cylinder 6
- Wiring or connector fault to coil/injector on cylinder 6
- Low battery/insufficient cranking voltage
Symptoms
- SES/MIL (check engine light) illuminated at/after start
- Engine cranks but struggles to start or fires unevenly
- Rough/cranky idle immediately after start (may clear after warming)
- Reduced engine power right after start
- Possible visible uneven exhaust smoke or smell of unburnt fuel at startup
- Stored freeze-frame data showing misfire count on cylinder 6 during cranking
What to check
- Retrieve stored and pending codes and freeze-frame data (note battery voltage and load at time of event)
- Use live data to check cylinder contribution and misfire counters during a cranked start attempt
- Confirm battery voltage during cranking (should be >9.5V for most tests)
- Visually inspect ignition coil, boot, and spark plug for carbon tracking, oil, or damage
- Inspect coil and injector harnesses and connectors for corrosion, broken wires, or loose pins
- Perform a coil swap: move cylinder 6 coil to another cylinder and re-test to see if misfire follows the coil
Signal parameters
- Cranking battery voltage (V)
- Cylinder 6 misfire counter / cylinder contribution (%)
- Crankshaft and camshaft position correlation during cranking (°)
- Injector pulse width for cylinder 6 during cranking (ms)
- Ignition coil primary voltage and dwell, secondary waveform and spark signature
- Fuel rail pressure (bar/psi) at cranking
Diagnostic algorithm
- Connect scan tool, read MIL codes and freeze-frame; record battery voltage and conditions at event
- Attempt to reproduce: monitor misfire counters and engine data during a controlled start attempt
- Check battery state and starter cranking speed; confirm adequate voltage under load
- Visually inspect coil, plug, injector and wiring on cylinder 6 for damage or contamination
- Swap coil from cylinder 6 with another cylinder; if misfire follows coil, replace coil
- If coil swap does not move the fault, swap the injector; if misfire follows injector, service/replace injector
- Check spark plug condition and gap; replace plug if fouled or worn
- Perform compression test or leak-down test on cylinder 6 to rule out mechanical failure
- If mechanical is good, scope coil and injector signals during cranking to confirm proper timing and amplitude
- Verify fuel rail pressure and injector pulse width during cranking; correct fuel delivery issues if present
- Inspect cam/crank sensor signals and timing (VANOS/chain condition) if synchronization error suspected
- Repair identified faulty component, clear codes and perform repeated start cycles to confirm repair; advise further mechanical repair if compression/test indicates damage
Likely causes
- Failed ignition coil pack/module for cylinder 6
- Carbon-fouled or damaged spark plug in cylinder 6
- Injector stuck open/partial or electrically intermittent for cylinder 6
- Open/short in coil or injector harness for cylinder 6 or poor connector pin contact
- Low compression on cylinder 6 due to burnt valve, head gasket leak at that cylinder, or piston damage
- Weak battery or poor starter causing slow cranking and weak spark
Fault status
Status
Control module detected a misfire event on cylinder 6 during engine start/cranking and stored code P1352. Freeze-frame and misfire counters were recorded when the start misfire threshold was met. Code may be pending or confirmed depending on occurrence frequency.
Repair difficulty: Medium
Diagnostic time: 1.5 - 3.0 hours
