[QUOTE="DaBoss, post: 1051341, member: 74989"] Aloha Nick, Here are the main codes that come up: PO135, 141, 155, 161 and 443. Sometimes the first 4 only. Usually the vehicle runs fine. A few times at low rpm's it sputtered a bit. A couple of times the "Check Charging System" came on. That was strange as I had a brand new Denso alternator installed a few months ago. My mechanic with his tester showed me that the charging system is just fine, doing it's job. Is there a way to repair the ground circuits or does one need to find a good "remanufactured" PCM? Thank you for your help. Mahalo! [/QUOTE]
