Replying to: mlangali (Oct 29, 2006 12:27 pm) Our problems started when we had the engine changed out after the timing belt broke and trashed the original. I bought an OBD II computer to read the error codes and got knock sensor P0325 which will NOT trip the check engine light, and the occasional cylinder misfire P0360 which will. I looked at the manual to see how to change out the sensor, and found that it is a joke. You have to basicly take apart the top of your engine. To have a shop do it is tremendously expensive due to the man hours involved....Still..I would do it if I knew it would solve the problem. My understanding is that it probably won"t. Knock sensors themselves are very simple devices, basicly a microphone that hears the sounds of detonation, and then sends a small voltage to the ECM and retards the timing... Many things can 'set off' the knock sensor, and by the number of posts on this subject it is likely that we all have good sensors, and bad whatevers... I went to 4door.com and paid an expert 20 dollars for the information that some kind soul posted here by scanning the Manual...Thanks for that. I am going to trouble shoot the sensor circuit and see if the resistance and voltages are OK. I will tell you how this comes out. I will NOT replace the sensor, due to the high cost, until I know for sure that it is bad. As I have said, I suspect it is something else. |

Hello guys... From all the advise I have gotten, after extensive research, I have decided that it's a better idea not to change the knock sensor. Along with the 500+ cost, you could have problems later on such as coolant leaks and overall engine issues since it is a pretty major surgery to the engine. Instead switch to premium gas, and have the codes erased. Also , make sure that all your injectors and plugs are good. You may just have a misfire due to a bad injector. Since the sole purpose of the knock sensor is to help the engine deal with low octane gas causing premature detonation, you may be able to get around the issue by using premium gas. hope this helps... And thanks to all of you...I didn't know any of this stuff a few weeks ago. Good luck... |

I have a 1995 Villager. My radiator fan burned up causing some of the wires to melt. A new (after market) fan has been installed but since the repair, none of my power windows work. The work was done by a friend and we're both baffled. There was a previous post about this exact problem and he never received a response. I'm a rural mail carrier and I have to have working windows. Any help would be greatly appreciated!

#2069 of 2519 95 quest. Radiator fan and power windows stopped working by meshhomelife Sep 22, 2005 (7:26 pm) Bookmark | E-mail Msg The radiator fan blew a fuse and melted through the lead wires. When I stopped the car because it was getting hot, I couldnt roll up the windows. I replaced the fuse for the power windows but they still wont roll up. They dont seem to be connected in any way to the radiator fan motor. Do they possibly share a ground wire? The fan motor is shot. It costs 116 dollars from autozone. The dealer wants 340$. Does anyone think that these two problems are connected? The fuse for the windows did not blow, so i doubt that it has anything to do with the motor. The passenger side and driver side wont roll up. Does anyone know anything about this? The radiator fan looks easy, but does anyone know how to fix the windows?

Replying to: mlangali (Oct 29, 2006 12:27 pm) We had a similar issue. Local shop wanted $700 to replace the knock sensor. I said no. Meanwhile, the check engine light came and went (mostly my blushing bride drives this car). I got behind the wheel the other day and it felt and sounded like it was not firing on all cylinders. I checked the leads coming off the distributor and some of them were decidedly loose. They are a circular cylinder receptacle with a slightly smaller cylinder for the plug. I spread the plug a tiny bit with needle nose pliers and the connection became better and the check engine light went out and the engine seems to be firing on all cylinders. $700 indeed! Happy Holidays
