Similar to those gadgets use

Similar to those gadgets use on some home security systems that you normally see on every houses. I find them effective though.

Knocking sensor code

with the use of the code reader , we were able to detect what makes the service enggine lights on. Its says Knocking sensor. the reader clear the problem but lights turn back on the next day.Im using 87 octane chveron or 76 gas. And i dont hear knocking /pinging noise so far. What do you think is the issue on this one and is it really need to replace the knocking sensor.. wow i read the comments,, too much labor to take the parts out. thanks

knock sensor

I'm fixing to have my knock sesor replaced on my 2000 Nissan Quest. It's located in the engine block so it has to be done by a professional and the knock sensor itself is no bigger than a thumb and cost $111.99 at Autozone and that was the cheapest. Now the labor takes 10 hours so thats whats hurting.

Knock sensor

Who says that you need to replace your knock sensor. I have a 2000 Quest and I am also a mechanic. What is your mileage? Does your engine ping? What grade of fuel are you using? I would be glad to help if I can.

Knocking sensor issue

Mechanic found out its the knocking sensor that makes the service engine lights up. We clear the after using /reset with the code reader. But turns back on after the next day. im using chvron or 76 gas 87 octane, do you think i need to switch to midgrade or higher.You think major tune up will help stop the knocking sensor issue. Never replace the plug cable and cup and rotor yet, maybe also needed to replace the fuel filter?
Thanks , maybe you can give me tips

Knock sensor issue too..maybe

Hi,
I am new to this forum and I hope some one can help me also whith an issue that I have with my 2000 Nissan Quest GXE. I've had it since Oct 2003 when it had only 52K miles on it. Now it has about 113K miles.

Recently, I had my Radiator fan ON all the time while the car/engine is on. Intially, when the problem surfaced, I had a a 'plastic burning' smell inside my car. This caused my radiator fan to be on all the time, even after turning off the engine/car. It was on all night and drained my battery. Found a 'burnt' fan relay in the fuse box.

Had the computer scanned and the following code came up: P0325 which according to the computer, it is a 'knock sensor issue'. Now, a mechanic I know told me it would take about 5.2 hours of labor and about $190 for parts.

Does this make sense? I mean, the 'knock sensor issue' causing my fan relay to burn and the radiator fan to be on all the time.

Now he told me that the Radiator fan being on all the time is not a big issue, but that I should change the sensor.

What do you think?

NOTE: My engine does NOT ping. I've been using regular (87 Oc) gas all this time. And the 'check engine' light did NOT come on even when the problem first appeared about a week ago. The car is running good for the most part.

TIA
David.
