I own a 95 Toyota Camry 4cyl, 5sfe. I have recently had a head gasket blow, so I replaced it and every gasket that you take off to get to it. Also replaced timing belt and water pump. Had the head worked on and a few other minor things. I got it all back together and had a few issues I worked on but now I'm down to what I hope is just a couple left.
1.) My radiator fans only run with the a/c on. I replaced all the temperature sensors except the one on the bottom of the radiator, but it has been thoroughly cleaned. The fans not running is causing my car to get hotter than normal when I'm not parked or at low speeds w/o the air on.
2.) My car is now sending a code 52, which is a bad Knock Sensor and/or wires to the knock sensor. I don't know much about knock sensors so forgive me if my next couple of questions are stupid ones. Will a bad knock sensor cause a car to knock worse? Will it cause bad ignition timing? If yes to these, are there any normal issues with these, or do they go out after so many miles? I am sure that it is the original, and it does have 227,xxx on it. Are there any ways to "save" one from having to buy new, because the only OEM one I found is expensive.
Thanks for all the help.
