P0302 on a Toyota Camry
P0302 means cylinder 2 Misfire Detected. On the Camry, a few causes come up far more than others.
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 common causes on the Camry
- 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 P0302 costs to fix 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.
Year, engine and mileage change the answer. Start a case and Redline weighs these causes against what your car shows, then names the check that would settle it.
