How many ignition coils does a 2007 Lexus ES 350 have?
Six ignition coils, one for each cylinder, in a coil-on-plug configuration on the ES 350’s 3.5-liter V6.
Engine and ignition layout
The 2007 Lexus ES 350 uses the 2GR-FE V6 engine. Each cylinder has its own ignition coil placed directly over the spark plug — a coil-on-plug (COP) setup. This design eliminated the traditional distributor and improves spark timing accuracy and durability across driving conditions.
Coil-to-cylinder mapping
With six cylinders, there are six ignition coils. The COP design assigns a dedicated coil to each cylinder (Cylinders 1 through 6), providing independent ignition control for each firing event.
Before detailing maintenance considerations, here are the core features of the coil arrangement:
- Six ignition coils, one per cylinder
- Coil-on-plug (COP) configuration
- Integrated with the 2GR-FE V6 engine’s ignition system
- Eliminates distributor-based ignition and high-tension wires routing
- Typically serviceable by replacing individual coils if faulty
Conclusion: The ES 350’s ignition system uses six individual coils, aligned with each cylinder, in a coil-on-plug arrangement common to Toyota/Lexus V6 engines of its era.
Maintenance and troubleshooting considerations
Problems with ignition coils can cause misfires, rough idle, reduced power, or a check-engine light. Common diagnostic steps include scanning for misfire codes (P0301–P0306), inspecting spark plugs and coil boots for cracks, and testing coil resistance with a multimeter. Faulty coils are often replaced individually, though some service approaches favor coil packs if multiple coils fail or if the vehicle uses a combined pack in specific trims.
Summary
In summary, the 2007 Lexus ES 350 employs six ignition coils—one for each of its six cylinders—configured in a coil-on-plug arrangement as part of the 2GR-FE V6 ignition system. This setup supports precise ignition timing and reliable performance across driving conditions.
