Severity
high
Left alone, this one tends to take other parts with it.
Can you drive it
Not for long
Driving on this one risks further damage. Get it to a shop rather than carrying on with it.

Coil pack 3 fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0353 is the cylinder 3 ignition coil primary/secondary circuit fault.
Cylinder 3 location
Ford Modular 4.6/5.4 V8 = third on bank 1 (passenger side), GM LS V8 = bank 1 (driver side) middle-front, Chrysler Hemi = bank 1 driver-side second position, BMW inline-6 = middle of engine, Toyota 2GR-FE V6 = front bank middle. Cheapest-first diagnostic: pull the cylinder 3 coil, inspect the boot for carbon-tracking (black streaks running down the ceramic insulator on the spark-plug side mean secondary arcing — replace boot and coil), and swap with cylinder 1. Clear codes, drive cycle: if P0351 appears and P0353 disappears, you've isolated a $35-$120 coil failure. If P0353 persists at cylinder 3, backprobe the trigger pin and scope for the ECM-commanded pulse (0-5V or 0-12V square wave depending on platform), verify B+ feed is 12.0-12.6V key-on and 13.5-14.5V running. Resistance check the trigger wire ECM-to-coil — should be under 0.5 ohms; anything higher means a chafed wire (intake-manifold harness rub-throughs are the textbook fault on Ford and Nissan platforms). Don't skip the spark plug — a cracked or oil-fouled cylinder 3 plug throws a coil-circuit code on some platforms because the coil sees the abnormal secondary load as an open circuit.

- 2004-2010Ford 5.4L 3V cylinder 3 P0353 is identical-cause to P0351/P0352 — TSB 08-7-6 coil/boot kit, plus the cylinder 3 plug is the one most likely to break off in the head on the early three-valve plug design (use penetrating oil and the Lisle 65600 broken-plug extractor; this is a $30-$200 sidequest if it breaks).
- 2010-2017Ford 3.5L EcoBoost cylinder 3 P0353 often presents with carbon-fouled intake valves alongside coil failure — direct-injection carbon buildup raises in-cylinder pressure and stresses the coil.
- 2005-2013GM 5.3L LS truck cylinder 3 P0353 from Delphi D585 failure, swap to D514A.
- 2007-2013BMW N54 cylinder 3 P0353 from Eldor coil batch failure plus the well-known N54 high-pressure fuel pump issue compounding misfires.
- 2007-2014Nissan VQ35 cylinder 3 P0353 from front-bank coil failure and valve-cover gasket oil leak.
- 2003-2009Toyota 4.0L 1GR-FE cylinder 3 P0353 — Denso COP, replace with OE Denso, aftermarket coils on this engine fail in months.
Estimated repair$35 (one coil) to $450 (full coil set + plugs + valve cover gasket).

How do I diagnose a P0353 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
