P0302 on a Toyota Camry
Cylinder 2 Misfire Detected
2.4L 2AZ-FE and 2.5L 2AR-FE fours plus the 3.5L 2GR-FE V6.
What P0302 usually means on a Camry
P0302 flags a misfire on cylinder 2 specifically. The diagnostic path mirrors cylinder 1 — coil, then plug, then injector and compression. On V6 Camrys cylinder 2 lives on the rear (firewall) bank, which makes access tighter than a front-bank cylinder. Expect a modest idle shake that worsens under load.
Most likely causes on this model
- Weak coil on cylinder 2
Move the No.2 coil to another cylinder; a following misfire confirms it.
- Worn or fouled plug
One tired plug is enough — inspect for oil fouling on the 2AZ-FE.
- Injector fault on cylinder 2
A partially clogged injector leans that cylinder out.
- Vacuum leak near the No.2 runner
A localized intake or PCV leak can single out one cylinder.
What it costs on a Camry
On the four-cylinder this is a cheap coil-and-plug job. On the 2GR-FE V6, cylinder 2 sits on the rear bank under the intake plenum, so labor climbs if the coil or injector needs replacing. Test by swapping the coil before buying parts.
