What does the code p0110 usually indicate? Check engine light has been off
and on for several months.

99 Accord 4 cyl

It would have taken less time to Google it than to post here.

No such code number on Hondas.

How did you get that number?

Honda does not use all the codes in that list. P0110 is not a valid code
for the OP's ECM.

Honda only uses these codes (up to the '03 MY):

I'd like to know a bit of the OP's car's history.

should also mention that a code p0420 is showing up.

the check engine light will light, but may go off after a few days.
currently, the CE light is off, but was on until yesterday.

had timing belt changed at 105000 miles (by Honda dealer). CE light came on
shortly thereafter.

Sounds like maybe (and this is mostly just me guessing wildly) your coolant
temp sensor is either unplugged, loosely plugged, or defective, and that's
throwing off the ecu enough to skew the mixture and thus the catalytic
converter's having a hard time doing its thing... or maybe due to erroneous
temp readings, the ecu just thinks the converter isn't up to snuff.

The more qualified guys I'm sure will throw in their 2c worth.

OK, so you have a P0118 and a P0420. which came first? Did one cascade
from the other? Nobody knows at this point.

You mention no other symptoms.

P0118 is a coolant temp sensor (voltage too high) error. P0420 means the
cat's efficiency has declined.

However, the timing belt having been changed points to a possible error
in installation, which could /possibly/ cause your problems. If the
engine runs the same as before, the belt's probably not off by a tooth.
If the engine sounds/runs differently than before, get the belt
alignment checked.

Make sure somebody checks to make sure all the connectors are properly
hooked up, especially the ground wire at the thermostat housing and the
eninge ground wire between rad support and the valve cover.

As far as the MIL ("Check Engine" light) goes, I would have the codes
cleared first. At the next illumination of the MIL, get the codes read
again (and recorded!). It may well be that one of the codes was due to a
transient and will not recur. You need to find out if it's the same
codes coming back, or different ones each time.
