hi guys, I have another weird problem, i guess this is a continuation of my previous problem, http://forums.g2ic.com/showthread.php?215015-Check-engine-light-but-ECU-red-light-not-flashing

now everything works fine from that previous problem but now new ones emerge
now my problem is my radiator fan in not turning on the right temperature, it turns on just before the hot at the meter and it doesnt pass that line but its scary cause its just a few millimeter away from hot and i know its not normal for the fan to turn on at that mark, changed the coolant temp sensor, changed the coolant temp sender what could be the problem now?

and also my idle goes up and down its fluctuating its hunting whatever you call it, can’t find any vaccum leaks bled the coolant system a numerous time and my car isn’t doing this until i did all of the above, not sure if its because the computer is sensing that the system is overheating that’s why its doing what its doing not really sure

please someone help me again like the previous problem i had

thanks a lot G2ic

fixed it, it was the new sensor that i put in, apparently the aftermarket replacement parts is no good, i replaced it with the old oem and it fixed the problem, that new aftermarket replacement sensor was giving me false readings.

hope this helps anyone who encounter this kind of problem.

Aftermarket sensors can be crap… WHen I replaced my Oil Pressure sensor both the oreilly & autozone sensors weren’t even the proper thread pitch. I had to trek all the way to a honda dealership and get an oem sensor.

rewiring like ^^^ did is an option, but I prefer to have all the systems functioning properly.
