Is It Safe To Drive My Subaru Legacy With The Check Engine Light On For Knock Sensor, Code PO325
I just went in to get my transmission checked out today. My car has been feeling like it has less power and/or slippage in the tranny. The mechanic took it for a ride and said it felt fine. But he did read my check engine light, which gave him the code for Knock Sensor Circuit Malfunction. I plan on getting it fixed- but can’t for another two weeks at least- Is it safe to keep driving it? I don’t want to break down OR ruin my poor car..
My subby is a 1999 and has about 113,000 miles on it. It’s been good to me so I don’t want ruin it if I can just put the bill on my credit card haha. Please let me know, I have no knowledge about cars!!

Knock sensor prevents engine fuel detonation. This is a condition inside the piston where the gasoline EXPLODES instead of burning. This WILL destroy your engine from the inside.
It is NOT that expensive NOW. You wait, it will get VERY expensive.

For now, use super (premium) gas to prevent engine knocking. Engine knocks more easily in
(1) hot weather
(2) heavy acceleration
(3) heavy load (lots of people)
(4) climbing up hills.
So there’s not much you can do about #1. But avoid all of the others as you drive your car to the garage for the fix.
I’m not terribly knowledgeble on vehicles either, but I have the exact same car with the same problem! So far, I’ve driven it for about two years with that light going on and off and it’s been fine. But maybe I’m doing something really wrong… haha
I’ve been driving my 2000 Daewoo Nubira for 8 years now with that stupid Knock Sensor warning. It turns off and then turns on again every now and then. Unfortunately, I have no idea if the light is turning on for the Knock or if it’s something serious. Apparently I can pay a few hundred dollars to change it, or just deal with it. I chose to deal with it.
The knock sensor is there so that it can detect an internal problem in the motor so I would not drive it and as for the answer above, well that is why we stay busy because of people like that….
Probably not the best idea, electronic ignition and the computer may try to compensate by adjusting the timing but you should be alright till you get your subby fixed. keep an eye on the temp and make sure it does not get to hot and if you hear it knocking shut it off. thanks:)
The Knock Sensor Controls the Ingnition timeing meaning bad performance and bad fuel milage as for harming the Engine if not repaired soon yes
1…if u are going to fix it in a few weeks its ok to drive….2…try premium gas…it may run better…the engines of today are aluminum and are destroyed easily…..keep oil,,,coolant and other fluids topped off.
