I have a 2001 Dodge Maxi Van with 72k miles on the 5.9 engine. My
check engine light is on, and the only code stored is P0601, which
indicates a PCM failure. The engine seems to run normally,
transmission shifts normally, etc. I've erased the code a few times by
disconnecting battery power, but the code always comes back after just
a couple minutes of run time.
This vehicle is normally driven around town, so I've just put repair on
hold, but we are now planning a longer trip (Florida to Colorado and
return). Is this going to cause a problem on the road? Funds are
llimited and I'd prefer to put off the repair if possible.
