Hey, well long story short, I put a scan tool on it and it gave me the CEL code P0340 (camshaft postion sensor a, circurt malfunction bank 1). So I did a continuity test on the pins of the connector of the CMP. Pin one to ground has to be around 4.5 to 5.5 voltage, it came up as 4.99 which is good. Now when I did pin 2 to ground it came up as 2.39 volts, but it's suppose to be between 8.5 and 9.5. So I spliced my newly CMP connector at pin 2 (yellow wire), and I wired it straight to the yellow wire via a new wire at the PCM to see if there is a short and it still is reading 2.39 volts. I read the wiring diagram and the crankshaft position sensor and VSS is on the yellow wire as well and it is not throwing any codes for them. My consensus is that maybe my PCM finally went? I'm not sure where to look after doing all that.
Thanks guys,
-Miguel
