1997 voyager through a p0202 code Injector Fault. I had 3 people tell me it is your PCM so I went and found one and installed it. Ran good for an hour went 2 blocks faulted again. Then we Replaced the Injector wiring Harness as several people had suggested .... it ran good for Maybe 3 or 4 days then it Rained real hard and Faulted again P0202. seems to be a moister issue.... it happened a few months back when I was in a big Rain storm .... Faulted with a P0202 code and would not run good for a few days ... dried out and fault went away. Does anyone have some IDEA what is Going on so I can fix Her. the Minivan get 24.8 MPG and I really need Her. I use it to move my Old Car Parts around. Thank You, Allen

I would also check the harness and connector for water-tight integrity. Use a quality dielectric grease to seal it if needs be.
