My '04 TBlazer EXT LS 4.2L I-6 2wd 96k mi has a "CHK ENG" light that says the fan clutch needs to be replaced. It only lights up from time to time but this issue started over 2 years ago. The fan clutch is in fine working order insofar as that I've had no overheating problems with thousands of miles on it since the problem arose. The past two years I've gotten the TB inspected while the chk eng light wasn't lit up - no problem. Now I'm overdue for inspection and the light won't turn off. My mechanic just shrugs his shoulders and says it'll be $600. If anyone knows something I could try before replacing a working fan clutch, it would be much appreciated.
Here are the error codes
P0495 Fan Speed High
P0135 O2 Heater Circuit (Bank 1, Sensor1)
Code0495 definition : Fan speed too high for a predetermined period of time.
