A P0303 code on your 2021 Honda Pilot indicates that the engine control module has detected cylinder 3 misfires beyond acceptable parameters. This three-row family SUV features Honda's proven V6 engine.

2021 Pilot Powertrain

The 2021 Honda Pilot is powered by a 3.5L V6 engine producing 280 horsepower. This naturally aspirated engine has an excellent reliability track record across Honda and Acura vehicles.

V6 Cylinder Configuration

In Honda's V6, cylinder 3 is located on one of the two banks. Bank-specific issues including fuel trim imbalances should be considered along with individual cylinder components.

The Pilot serves as primary family transportation for many owners. Honda's reputation for reliability makes misfires relatively uncommon. Address them promptly.

Three-Row Capability

The Pilot's three rows make it essential family transportation. Ensure reliable operation by addressing any engine issues immediately.
