After replacing coolant and thermostat on a 2007 accord, 2.4L, what could still be giving a po 128 code?
Checked the wiring and connections on the maf, and ect 1 and 2, all look good. Any
thoughts? I read it's possible the ecu needs a reflash?
http://www.obd-codes.com/p0128 -- check this out for possible causes and solutions. Is your coolant level correct? Also could be a stuck open thermostat or cooling fans staying on to much at an idle.
I've checked that out. Like I said, I already replaced my thermostat and coolant. Fans are working correctly too.
Have you checked you coolant temp sensor?
Yes, short of replacing it. The wiring and harness look fine, no corrosion, etc.
