I got P0339 HONDA CKP SENSOR A CIRCUIT INTERMITTENT (on my 2008 4
cyl Honda Acord. ... My INNOVA OBD2 scanner also pulled a 10 second
BATTERY Monitor scan test resulting in 11.84 VOLTS (at ECM vs 12.5v at
my battery terminals) ... while saying: "BELOW ACCEPTABLE LIMITS". ... I
believe my small 4 cylinder Napa battery has been reading marginally
lower voltage for a couple years plus (& possibly the biggest source
of my problem). I also believe some higher end batteries of same small
size would retain higher voltage. My Choice now is: I am going up to the
24F larger size battery (spec 6 cylinder Accords) in AGM format as my
best long term fix. I lost Engine torque when that code tripped. ...
Erasing that code with my Innova scanner after study resulted in no more
problems or codes returning (so far/ even though my 24F AGM battery
order in progress makes that a near future project). ... My two cents
as a past mechanic shop owner who still does all my own wrenching :+) -
Thank you for this information! I've been dealing with a P0339 code after replacing the CKP sensor several times and erasing the MIL codes. It seems to be getting worse and my car went into limp mode causing misfires until I once again ereased the MIL code. I'll try checking the voltage on my recently replaced Costco/Interstate 4cyl spec battery. New starter and alternator has been replaced too and was just about to pay a visit to the dealer until I read this post.
