[QUOTE="Arnoldb.1, post: 1540143, member: 30179"] I’m doing the wire test for the P1670 code, on FJ11 Check for an intermittent short to ground Says: measure resistance on FDCS circuit 821 BR/O between battery ground and PCM test pin 95. Measure resistance on EF circuit 818 between battery ground and PCM test pin 48. Ask if reading remain above 10,000 ohms throughout procedure? How do you test this? I believe I’m doing something wrong, cause I put black lead on battery negative and red lead on each of those Pins and I get nothing on ohms reading [/QUOTE]
