A P0306 code on a 2024 Acura TLX indicates a cylinder 6 misfire, but the validity of this code depends entirely on which engine your TLX has.
2024 TLX Engine Variants
- Standard TLX: 2.0L turbocharged 4-cylinder (272 hp) - P0306 is invalid
- TLX Type S: 3.0L twin-turbo V6 (355 hp) - P0306 is valid
The Type S is the only 2024 TLX with a V6 engine. If you own a standard TLX with the 2.0L turbo-4, a P0306 code requires investigation since that engine only has 4 cylinders.
Type S V6 Cylinder 6 Misfire Causes
- Ignition Coil Issues: Coil-on-plug failure on cylinder 6
- Spark Plug Problems: Worn or fouled spark plug
- Fuel Injector Failure: Direct injector clogging or malfunction
- Boost System Leaks: Twin-turbo system air leaks
- Carbon Deposits: Intake valve carbon affecting cylinder sealing
- Mechanical Issues: Low compression from valve or piston wear
