Check Engine Light/Thermostat Code despite entire system being serviced
I have a 2006 Honda Civic Hybrid. About 6 weeks ago my check engine light
came on and the thermostat code came up. Ok, no problem, my mechanic
changed my thermostat. Since then, it has been back no less than 8 times
because the codes keep coming back after 2 days. The car has never
overheated and the temp always reads fine. All hoses have been changed.
The second thermostat has been changed. The radiator has been checked for
leaks. The head gasket is not blown. The thermostats have been checked for
voltage compatibility. The engine block is reading within 1 degree of what the
thermostats read with two different spot thermometers. My mechanic took it
to a Honda Dealership after hours as one of his friends works there, and they
couldnt find anything wrong with the car, other than the light still being on and
giving out thermostat codes.
The car is a bit jumpy from stop with the AC on, but that has always been the
case. Otherwise, everything is normal.
I have to have my inspection in less than 3 weeks, so any ideas about what
this could be would be really appreciated. I absolutely cannot afford to replace
my car for not passing inspection, especially as it is not actually giving me any
problems outside of the damned light.
