2002 Accord 2.3L: coil-on-plug, 7 ft-lb bolt, Delphi GN10322
The 2002 Honda Accord with the 2.3L F23A1 engine uses a true coil-on-plug (COP) ignition system with four individual ignition coils sitting directly atop each spark plug. There are no plug wires, so coil failure causes a direct misfire on that cylinder.
Each coil is held by a single 10mm bolt torqued to 84 in-lb (7 ft-lb) — overtightening strips the aluminum threads in the valve cover.
Disconnect the 2-pin electrical connector from each coil before unbolting; the connectors have a locking tab that must be depressed to release.
Pull the coil straight up with a gentle twisting motion; the rubber boot may stick to the plug — a coil boot puller helps prevent wire damage.
OEM coil part number: Honda 30520-PAA-A01; aftermarket equivalent: Delphi GN10322 or Denso 673-2300.
Apply dielectric grease inside the coil boot before installation to prevent arcing and moisture intrusion that causes intermittent misfires.
If only one coil is failing, move it to a different cylinder and clear codes — if the misfire follows the coil, you've confirmed the failure.
The 3.0L V6 uses a distributor and plug wires — this guide applies only to the 4-cylinder 2.3L F23A1 engine.
