Do you have any codes that indicate a faulty ignition coil?

<<Rant Mode ON>>

Ignition coil issues (weak spark) will cause the same codes as spark plugs: misfires.

Some cars were fitted with coils that would fail early. (Thinking of the kid's Gen1 Fit...replaced them all at 120K miles) Wide plug gaps result in stress to the coils (takes more 'lectricity to spark). BUT the Iridium plugs that Hondas specifies work so well that gaps don't appreciably widen even after 100,000 miles.

The coils on the CR-Vs K Series engines seem to be robust..that is, until cheap aftermarket coils are installed.

I 'm guessing that many shops want to replace coils just to assure that a return visit doesn't happen. After all, the coils need to be removed to replace plugs. And, the owner is paying. (Sort of like many shops' practice of ALWAYS replacing brake rotors along with new pads, instead of measuring rotor thickness to determine if they are within spec) <<SIGH>>

If I only have a basic OBD II scanner (e.g. ANCEL AD410) would I be able to read that misfires codes?

YES.

Also, my 2011 V (currently about 105K miles) currently has intermittent/inconsistent hesitation and minor vibration when stopped in D gear (when shift to N gear it's less vibration). Is this a sign that my Spark Plugs should be changed now? Thanks!!

The 2011 is due for a spark plug change (recommended ~10 years or 100,000 miles) and a valve lash adjustment.
SEARCH the forum for a needed transmission issue...but replace the ATF first. Do an ADVANCED SEARCH.

Yeah, 100 to 110K miles is is the recommended replacement interval on the K Series engine.

Thanks, I updated that Service Manual topic to include the information you reported.

^^ If someone verifies this I will update the sticky topic.


Could the difference be between the 2.4L engines and the 2.0L?
