P0353 on Toyota: Causes, Symptoms and Fix Cost

Quick Answer
Moderate SeverityNot safe to driveToyota

P0353 on a Toyota means the ECU saw an electrical fault in the coil 3 primary or secondary circuit. Usually a dead coil-on-plug, sometimes wiring or connector corrosion, rarely the ECU driver itself.

Typical repair cost, all makes€28 - €1500

Connect any standard Bluetooth OBD2 adapter to your Toyota and Skanyx tells you what P0353 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

What does P0353 mean on a Toyota?

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Toyota models that log P0353.

Toyota Camry

2007-2017 (2AR-FE 2.5L I4, 2GR-FE 3.5L V6)

Toyota coils are generally durable and tend to fail only at high mileage. If P0353 appears on a 2GR-FE V6, cylinder 3 sits on the rear bank behind the intake plenum, so labour is higher than on the front bank.

What causes P0353 on a Toyota?

Beyond the generic causes listed on the main P0353 page, these are the patterns noted for Toyota models:

Toyota CamryCoil failure at very high mileage
Toyota CamryRodent damage to the coil harness on vehicles stored outdoors
Toyota CamryIridium plugs worn past their service interval

How to diagnose P0353 on a Toyota with OBD2

Follow these steps to pinpoint the root cause of P0353:

  1. Read all stored codes. If P0303 is present alongside P0353, that confirms cylinder 3 is actually misfiring and not just an electrical glitch.
  2. Pull the coil on cylinder 3 and inspect the boot for cracks, carbon tracking, or oil in the plug well.
  3. Swap coil 3 with coil 1 or 2. Clear codes and drive. If the fault moves (P0351 or P0352), the coil is bad. If P0353 stays, the coil is fine.
  4. Pull the plug on cylinder 3. Replace if the electrode is worn, oil-fouled, or beyond the service interval (typically 60,000 km for copper, 100,000+ for iridium).
  5. Inspect the coil connector for green corrosion, spread pins, or a broken lock tab. Wiggle-test the harness with the engine idling.
  6. Back-probe the connector with a multimeter: verify battery voltage on the power pin (key on, engine off) and continuity from the trigger pin back to the ECU.
  7. If coil, plug, and wiring all test good and the code returns on the same cylinder, suspect an ECU ignition driver failure. That needs a shop with proper diagnostic gear.
