Parts for your 2008 Toyota Camry-Ignition coils

2008 Toyota Camry ignition coils

Ignition coils are absolutely fitted to the 2008 Toyota Camry. Toyota’s factory repair information for the XV40 Camry (2007–2011), along with the Toyota Electronic Parts Catalogue and DENSO OE listings, specify a coil-on-plug ignition system across the 2.4‑litre petrol (2AZ‑FE), the 3.5‑litre V6 (2GR‑FE), and the Hybrid’s 2.4‑litre Atkinson-cycle (2AZ‑FXE). Each cylinder has its own coil mounted directly on the spark plug.

On this Camry, the ignition coil’s job is to take the car’s 12‑volt supply and step it up to tens of thousands of volts to jump the spark plug gap. Being coil‑on‑plug keeps the spark strong and precise, reduces energy loss through leads, and lets the engine computer control each cylinder individually for smooth running, good fuel economy and lower emissions.

There’s no fixed replacement interval for coils, they’re usually changed when they show signs of trouble. During routine servicing—especially when spark plugs are due (often around 160,000 kilometres for the iridium plugs used in these engines)—it pays to inspect the coils and boots. Look for cracking, hardening, oil in the plug tubes, or carbon tracking. Replace any suspect boots, tidy up the plug wells, and use a smear of dielectric grease on the inner boot to help sealing and future removal.

Typical coil symptoms include:

• Rough idle, hesitation, or hard starts
• Check Engine Light with misfire codes (P0300–P0306) or coil circuit codes (P0351–P0356)
• Higher fuel use and a sluggish feel under load

Diagnosis is straightforward: rule out worn plugs first, then swap a suspect coil to another cylinder and see if the misfire follows. When replacing, stick with quality parts (Toyota/DENSO or equivalent). Don’t overtighten the small coil hold‑down bolts—snug to the factory spec—and make sure the connectors click home cleanly.

Access on the 2.4‑litre is easy under the bonnet cover, while the V6’s rear bank sits near the firewall and can take extra time, some workshops will suggest tackling rear‑bank coils and plugs together to save labour later. For the Hybrid, coil service is on the 12‑volt side, but always power the vehicle down properly and disconnect the 12‑volt negative terminal before starting work.

Kept in good nick, the Camry’s coils help it start promptly, idle smoothly, and stay frugal on petrol—no dramas.

Popular questions

How many ignition coils does a 2008 Toyota Camry have?
The 2.4‑litre four‑cylinder and the Hybrid each have four ignition coils (one per cylinder). The 3.5‑litre V6 has six—three at the front of the engine and three at the rear bank near the firewall.

What are the warning signs of a failing coil on a 2008 Camry?
Expect rough running, a flashing or steady Check Engine Light, misfire fault codes, poor fuel economy, and a lack of punch on hills. If a single cylinder is playing up and the fault follows a coil when swapped, that coil’s on the way out.

Do ignition coils need replacing with the spark plugs?
Not as a rule. Coils aren’t a scheduled service item and often last well beyond the plug interval. That said, if the vehicle has high kilometres or a history of misfires, it can be sensible to replace tired coils or at least the rubber boots while the plugs are out—especially on the V6’s rear bank where access is tighter.
