Answer 1
It means...intake manifold runner control malfunction. From the shop manual: The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle. -

Comment 2
It's not a simple diagnosis and repair; I do recommend a technician look at it - one versed in the operation of this system (IMRC). Check engine lights indicate emissions and performance issues - I would say that it is something that requires inspection and repair. -
