The check engine light on my 2010 Rav 4 Ltd edition (170k miles in great shape) comes and goes. It seems to come on after a rain, cold or damp period. Then it will go off for no reason. Then back on–just in time for inspection. The code is P0607 ECM Control Module. So far I have checked the following:
- Brand new battery, all connections good and clean.
- just ran a ground from the neg side of the battery to where the control unit clamps–time will tell.
Car is running fine but it does need an inspection.
Wondering if anyone had any ideas or if this has happened to other Rav4 owners?
