Rep Power: 0 p1505 and p0505 after fluid replacent
I just finished a ton of work on my son's 2003 civic. New radiator, timing belt, refurbished head, etc. it starts and runs great...for a few minutes; then rpm goes up to 2100 or so and i get p1505 and p0505 codes. Could this be caused by coolant not beong bled properly yet?

If you think a good mechanic is expensive, try hiring a bad one

Listen for sucking (hiss) sounds, and idle RPM higher than normal
After you solve the codes, make sure to do an idle relearn

That's the thing, though. Idle rpm is spot on now. Car is back in son's possession, but I'll check with him later this week and see if the code posts again.

Check for poor connections or loose terminals at the IAC valve (and at the PCM) as well.
Check the PCV valve and its hose for leaks.

Thanks. Will do. May take the iac off and clean it out really well, too. I'm thinking I dislodged some crap by trying to clean out the throttle body when everything was off for the head replacement.
