An oil leakage within the spark plug wells of a Honda CR-V can disrupt the ignition coil’s functionality, leading to engine misfires and potential coil damage. Typically caused by a faulty spark plug tube seal in the valve cover, replacing these seals often resolves the issue.
External Damage
If evidence of rodent activity such as bite marks is found under the hood, a thorough inspection of all cables and hoses, including electrical wires and ignition coil connectors, is crucial to identify any damage. Faulty electrical wires or connectors may trigger error codes P0350 to P0362 on a code scanner tool, indicating an ignition coil circuit malfunction.
Blown Fuse
A blown fuse can halt the operation of the Honda CR-V’s ignition coils by interrupting the electrical circuit. Consult your vehicle’s owner’s manual or fuse box cover for the specific location of the coil fuse, and replace it with one of matching amp rating if necessary.
Symptoms of Honda CRV Ignition Coil Issues
Identifying ignition coil problems in your Honda CRV is crucial for maintaining optimal performance. One key indicator to watch out for is a noticeable decrease in engine power and efficiency during acceleration.
Additionally, a rough idle or shaky engine operation can signal potential issues with the ignition coils. When starting the vehicle, if you experience difficulty or hear unusual sounds like popping or backfiring, it may indicate a faulty ignition coil.
Another red flag is an illuminated check engine light on your dashboard, signaling that a diagnostic scan may reveal ignition coil problems.
Moreover, sudden drops in fuel efficiency or frequent stalling of the engine could also point toward ignition coil issues. Pay close attention to any strong smell of burnt rubber or wire insulation coming from under the hood, as this could be a sign of overheating coils.
Lastly, if you notice visible physical damage such as cracks or corrosion on the ignition coils themselves, it is advisable to seek professional assistance promptly.

Here, we’re going to explore some of the common ignition coil issues
Rough Running with Strange Smell
Numerous Honda CRV owners have experienced engine trouble that is often accompanied by flashing check engine lights, rough running, and strange smells. A blinking check engine light indicates a serious misfire issue, and it is crucial to stop driving the vehicle immediately.
The problem may stem from issues with the ignition system, timing, or fuel. While ignition problems are common in most cases, it is recommended to have the vehicle scanned for Diagnostic Trouble Codes (DTCs). Monitoring fuel trims using a scanner is advisable; if this is not possible, be prepared to reassess the situation if the check engine light reappears.
Excessive fuel consumption could potentially harm the catalytic converter, so it’s important to keep this in mind. The priority should be fixing the misfire. To diagnose further, examine spark plug 1 and inspect its center electrode for oil deposits which could indicate piston ring issues.
If gasoline residue is present, suspect fuel injector 1 malfunctions; if the plug appears clean and new, then focus on the fuel injector as a potential problem source. Check its electrical connection for any loose connections first before proceeding with further tests.
To pinpoint leaks or issues around fuel injector 1 or intake manifold areas close to cylinder 1, use WD40 or a similar substance while the engine is running.
Additionally, consider spraying around the intake manifold gasket and throttle body gasket thoroughly for potential leaks that may be causing problems near cylinder 1. It’s advisable to conduct a compression test as well to rule out valve issues.
Engine Misfiring
Owners of the 2020 Honda CRV have expressed frustration over an ongoing issue of continuous misfiring. Despite replacing spark plugs and coils multiple times, many are still experiencing the same problem.
Various potential factors can lead to engine misfires, including faulty spark plugs, injectors, ignition coils, crankshaft position sensors, or fuel injectors. Given that you have already replaced the spark plugs and coils, it may be prudent to conduct a swap test to eliminate other ignition-related issues.
This procedure entails exchanging the components of the problematic second cylinder with those of another cylinder and monitoring if the misfire code alters.
If the code remains unchanged, it indicates that the issue does not stem from the spark plug, coil pack, or plug wire of the second cylinder. Conversely, if the code does change, you have successfully pinpointed the defective component and can proceed with its replacement accordingly.
Vehicle Quit Working And Have No Spark
There are several possible reasons why a car may stop working and lose spark even after changing the Honda ignition coil. One common issue could be a faulty ignition control module, which is responsible for sending electrical signals to the coils.
