Parts for your 2020 Honda Cr-v-Ignition coils

2020 Honda CR‑V Ignition Coils: what they do and when to replace them

Yes, the 2020 Honda CR‑V uses ignition coils. Honda’s workshop information and parts catalogues for the 2020 model show a coil‑on‑plug setup—one ignition coil mounted directly on each spark plug for the 1.5‑litre turbo petrol engine, and a similar coil‑on‑plug arrangement on the petrol engine in the CR‑V Hybrid. Typical Honda part listings identify individual coils for each cylinder, confirming the system is very much part of this vehicle’s ignition design.

Ignition coils take the 12‑volt supply from the battery and step it up to tens of thousands of volts so the spark plug can fire cleanly under compression. With coil‑on‑plug, there’s no traditional high‑tension lead—each coil sits under the plastic engine cover on top of a spark plug, reducing energy loss and improving cold starts, fuel economy and emissions. The engine control unit times and drives each coil precisely, helping the CR‑V feel smooth and responsive in everyday Aussie and Kiwi traffic.

Coils aren’t a scheduled “consumable”, but they do live a hard life under the bonnet and can fail with age, heat or moisture. Common clues include a rough idle, hesitation under load, poor fuel economy, and a check engine light with misfire codes (for example, P0300–P0304 or coil circuit codes like P0351–P0354). If a misfire pops up, it’s smart to scan the ECU, swap coils between cylinders to confirm the fault, and check the spark plugs and coil boots while you’re there.

Good servicing practice on a 2020 CR‑V is to replace spark plugs at the interval in the maintenance schedule and inspect each coil at the same time. Look for oil in the plug tubes (a sign of a cam cover seal leak), cracked boots, green corrosion on terminals, or water ingress from over‑enthusiastic engine washing. If a coil is suspect, it can be replaced individually, just stick with genuine or quality aftermarket units. When refitting, seat the boot cleanly on the plug, use a dab of dielectric grease on the inside of the boot if recommended, and tighten fasteners to the workshop‑specified torque. Avoid driving long distances with an active misfire—unburnt fuel can toast the catalytic converter. With basic care, the CR‑V’s coils usually clock up many hundreds of thousands of kilometres without fuss.

• Symptoms to watch: rough idle, loss of power, harder cold starts, higher fuel use, and a flashing MIL under load.
• Pro tip: always rule out worn spark plugs before condemning a coil.

How many ignition coils does a 2020 Honda CR‑V have?

There are four—one per cylinder—on the 1.5‑litre turbo petrol engine. The CR‑V Hybrid’s petrol engine also uses individual coil‑on‑plug units. This design improves reliability and spark accuracy compared to older distributor or remote‑coil systems.

How long do the coils typically last?

They often last the life of the vehicle. Many go well beyond 100,000 km. Heat, moisture, and worn spark plugs are the main coil killers, so staying on top of plug changes and keeping water out from engine‑bay cleaning helps extend coil life.

Is it safe to keep driving with a bad coil?

It’ll usually run, but it’s not a great idea. A persistent misfire can damage the catalytic converter and may leave the CR‑V down on power at the worst time. If the MIL is flashing or it’s running rough, get it checked and repaired promptly.
