Checking Coil Pack

Recommended Posts

Hi,99 boxster base. Indie told me to check coil packs w/ multi meter. I'm getting .7 ohms on 2 outside contacts (primary) and 7.2 megohms on plug spring and center contact(secondary) they both seem out of spec. Am I doing this correctly? thanks v

OK ....getting .7 at the primary a little less than 1800 ohms on the plug connectors. Someone else said 5-7.2 K ohms between terminals 1 and 4 I'm getting 0. Pelican says 600 ohms on the secondary.... a little confused. Do you know anything about this. Just asking, want to be sure they're good before moving on into the misfire madness. Thanks V

Hi Loren, Codes as follows: PO304            1313      P1539

                                                  PO305            1314

                                                  PO306            1315


 I replaced the Plugs/AOS/MAF/Fuel Filter/Battery/Solenoid on Bank 2/Actuator Ramps on both banks/ I don't have a Durametric.  Codes have been bouncing back and forth from bank to bank. The codes above both appeared as CEL's and Pending at one time or another. The latest I replaced a weak and failing battery and thought I resolved it but about a half hr into a drive I get a CEL. For the most part the car was only at idle and not driven after all the work was done. Initially the original CEL was a P1539 that's why I replaced the solenoid(tested the solenoid for proper resistance and it failed took a chance and replaced solenoid only ) I recently got plates for it and drove about 40 miles after I replaced the Batt and thought I was good. Lately I've been clearing the codes to see if the DME will learn new Fuel Trim and I've been watching that...I got to the point where I brought it to an indie to pinpoint the problem and that's who told me to check the Coils before I brought it in. Could be a vacuum leak but not finding one.....knock sensors?? Be nice to drive it when the Spring comes!! Thanks V
