Positive Lead Negative Lead Pin Circuit Pin Circuit 14 - 15 -
Is the resistance between 4.0 and 7.2 ohms?
Yes INSTALL a new PCM. REFER to Electronic Engine Controls . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to Solenoid Body Strategy Download . No REMOVE the main control cover. For 3.5L Ti-VCT, REFER to Main Control Cover - 3.5L Ti-VCT . INSPECT the solenoid body for metal shavings on the exposed metal contacts or other components. CLEAN the solenoid body and RECHECK the resistance value. If the resistance value is out of specification and a short to ground is not found, INSTALL a new solenoid body assembly.
