My 98 Odyssey with 105k miles needs to get a clean emissions bill in the next 30 days or my registration gets suspended. The problem is that the computer is throwing a P1607 code for a general PCM or computer failure. I would like to avoid buying a new (or used) PCM until I can be reasonably certain that that will fix the problem. Anyone know if either:
- I can swqap out my parents' PCM from their 97 Accord to see if it fixes my problem?, OR
- where on the web to buy an inexpensive PCM unit and how to know which part my particular vehicle needs?, OR
- have any other ideas?
The background:
About a month ago I first started seeing an inconsistent transmission-related problem: occasionally the car goes into "limp home" mode (4th gear?) and I either have to drive it in low gear till I get to highway speed and put it back to D4, or pull over and turn the car off and then on again and the problem goes away. I brought it to a transmission guy who read both a torque converter problem code as well as the PCM failure code (P1607) and he recommended I see the dealer before making any tranny investments. I went to the dealer and they sold me an expensive tranny flush saying they thought my dirty fluid might have fouled a sensor. Dealer said not to be concerned about the PCM code (!)
So now I have to somehow clear the code and make sure it doesn't come back so I can at least have a registered vehicle in the good graces of the state DMV.
Any advice here would be appreciated! Thanks for your time!
