🔧 Ignition Coils - Replacement

On your CR-V, the ignition coils sit on top of the engine and can be replaced without removing major components. If you have a misfire, rough idle, or a check-engine light, replacing a weak coil can restore smooth running.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• Let the engine cool fully before starting. Coils sit near hot engine parts.
• Turn the ignition off and keep the key/fob away from the vehicle.
• Disconnect the negative battery cable if you want extra safety while unplugging coils.
• Do not pull on the wire harness. Press the connector tab first, then unplug it.
• If the misfire has been present for a while, inspect spark plugs too. A bad plug can damage a new coil.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the ignition coils

• Open the hood and secure it.
• Find the four ignition coils on top of the engine, above the spark plugs.
• If the engine cover is installed, remove it by lifting it straight up by hand.

Step 2: Disconnect the coil connector

• Use a trim tool or small pick to gently release the locking tab if needed.
• Press the connector tab and pull the electrical plug straight off the coil.
• Do not twist the connector or pull on the wires.

Step 3: Remove the coil hold-down bolt

• Use a 10mm socket, ratchet, and extension to remove the coil bolt.
• Set the bolt aside where it will not get lost.
• Keep hardware organized by cylinder.

Step 4: Pull out the old ignition coil

• Grasp the coil body and pull it straight up out of the spark plug tube.
• If it is stuck, wiggle it gently by hand. Do not pry hard against the valve cover.
• Inspect the rubber boot for oil, cracks, or burns.

Step 5: Install the new ignition coil

• Compare the new coil to the old one to make sure it matches.
• Push the new coil straight down into the plug well until it seats fully.
• Reinstall the hold-down bolt by hand first to avoid cross-threading.
• Use a 10mm socket and torque wrench to tighten the bolt to 10 N·m (7 ft-lbs).

Step 6: Reconnect the electrical connector

• Push the connector onto the coil until it clicks into place.
• Lightly tug on the connector to make sure it is locked.
• Repeat Steps 2 through 6 for each remaining coil.

Step 7: Reinstall the engine cover and finish up

• If removed, set the engine cover back in place and press it down evenly.
• Reconnect the negative battery cable if it was disconnected.

✅ After Repair

• Start the engine and let it idle smoothly for a few minutes.
• Check for a rough idle, warning lights, or misfire codes.
• If the check-engine light was on, clear the codes with a scan tool after the repair.
• If misfires return, inspect the spark plugs and coil connectors next.
