Parts for your 2015 Honda Cr-v-Ignition coils

2015 Honda CR‑V Ignition Coils

Based on Honda’s 2015 CR‑V Owner’s Manual, the Honda Factory Service Manual, and the Honda Electronic Parts Catalogue, the 2015 CR‑V petrol engines (R20A 2.0L and K24W 2.4L, common in Australia and New Zealand) use a coil‑on‑plug ignition system with one ignition coil per cylinder. Only diesel variants in some overseas markets omit ignition coils, using glow plugs and compression ignition instead. For local AU/NZ petrol models, ignition coils are absolutely relevant and fitted from factory.

On the 2015 Honda CR‑V petrol, the ignition coils sit directly on top of the spark plugs under the bonnet. Their job is to step up battery voltage to the high voltage needed to spark the air‑fuel mix, and the coil‑on‑plug layout helps deliver a strong, precise spark with minimal losses. With four cylinders, there are four individual coils, a failure in one can cause a single‑cylinder misfire.

There’s no fixed service interval for coils, but they work hand‑in‑hand with the spark plugs. Sticking to the plug replacement schedule (typically around 100,000–160,000 km for iridium plugs, check the owner’s manual for the exact figure) helps keep coil load down. When a coil starts to go, the car may show a check engine light, feel down on power, or run rough at idle. Left too long, persistent misfires can stress the catalytic converter, so it’s best not to put it off.

• Common signs a coil needs attention:
  • Check engine light with misfire codes (P0300–P0304).
  • Rough idle, hesitation on acceleration, or poorer fuel economy.
  • Intermittent stumble that’s worse in wet weather.
• Good maintenance habits:
  • Replace spark plugs on time, use the correct iridium spec.
  • If one coil fails at high kilometres, consider replacing the set for long‑term reliability.
  • Use genuine Honda or quality OEM‑equivalent coils (e.g., Denso) and avoid overtightening the hold‑down bolts.
• Basic replacement overview:
  • Remove the engine cover, unplug the coil connector, undo the small retaining bolt, and lift the coil straight out.
  • Inspect the boot for oil or moisture, if there’s oil, the rocker cover gasket may need attention.
  • Refit the new coil, ensure the connector clicks home, and clear any stored fault codes after a test drive.

Look after the ignition coils and plugs, and the 2015 CR‑V’s petrol engine will stay smooth, efficient, and ready for the daily commute or a long holiday run.

Popular questions about 2015 Honda CR‑V ignition coils

How long do ignition coils last on a 2015 CR‑V?
In Aussie and Kiwi conditions, coils often last well past 150,000 km, especially if the correct iridium plugs are fitted on time. They’re not a routine service item—replace them only if fault symptoms or diagnostics point to a failing coil.

Is it okay to drive with a misfiring coil?
It’ll usually get the car home, but it’s not ideal. Ongoing misfire can overheat the catalytic converter and increase fuel use. It’s best to diagnose promptly, swap coils to confirm the faulty one if needed, and replace it without delay.

Should all four coils be replaced at once?
If the vehicle has low kilometres and only one coil has failed, replacing just that coil is fine. At higher kilometres, or if multiple coils test weak, replacing the full set can prevent repeat visits and keep performance even across all cylinders.
