P0352 on Ford: Causes, Symptoms and Fix Cost
Quick Answer
Not safe to drive
P0352 on a Ford means the ECU saw an abnormal voltage pattern on the primary control circuit of ignition coil #2. In plain terms: cylinder 2 isn't getting a reliable spark command, so it misfires.
- Severity
- Moderate · Ignition
- Typical repair cost, all makes
- €60-€850
Connect a standard OBD2 adapter (Bluetooth LE on iPhone) to your Ford and Skanyx tells you what P0352 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Ford models that log P0352.
Ford F-150
2004-2014
The 5.4L 3V Triton's coil-on-plug units commonly fail at high mileage, and Ford changed the coil version during production, so match the replacement to the one fitted. Cylinder 2 is the second from the front on the passenger-side bank.

What causes P0352 on a Ford?
Beyond the generic causes listed on the main P0352 page, these are the patterns noted for Ford models:
Coil boot cracking and arcing to the cam cover bolt
: Ford F-150
Two-piece spark plug seizing in the head, previous plug change left the boot damaged
: Ford F-150
How to diagnose P0352 on a Ford with OBD2
- Scan for all stored codes and freeze frame data. If P0302 is also present, you've confirmed cylinder 2 is the misfiring one
- Pull coil #2 and inspect the boot for cracks, carbon tracking, and oil. Check the connector pins for green corrosion or a backed-out terminal
- Swap coil #2 with coil #1 or #3, clear codes, drive and rescan. If the P0352 becomes P0351 or P0353, the coil is bad
- If the code stays on cylinder 2, pull spark plug #2. Look for wide gap, oil fouling, cracked insulator, or wrong heat range
- Measure primary resistance across the coil terminals (typical 0.4 to 2.0 ohms) and secondary if accessible (5k to 15k ohms). Compare to service manual spec, not gut feel
- Key on, engine off: back-probe the coil connector for switched 12V on the supply pin. Cranking: verify the PCM is pulsing the trigger wire (test light flicker or scope)
- If supply, ground, trigger, coil, and plug all check out, scope the primary waveform. A missing or flat trigger points to the PCM ignition driver
- After repair, clear codes and run a drive cycle covering idle, part-throttle, and full-throttle to confirm the misfire counter stays at zero
