I'm sure a bad one can retard ignition timing far enough to cause running problems. Service manual says the intake manifold has to come off. IDK if there is a shortcut or not. 11-26-2012Registered!!

The car ran perfectly fine, started and everything, the thing it affects if even directly i don't know for sure is vtec monitoring. 11-26-2012Registered!!

It's a little difficult to get your hands in there but it is possible, if you take the intake manifold off, its extremely easy but it depends on what you want to tinker with. 11-26-20126th Gen Honda-Tech

Same goes for the Valve Lash I just did yesterday a Valve adjustement on a civic 97 Ex, lack of power really bad fuel economy ( around 300km per tank ) Checked with Xgauge Scan (Realm time fuel monitoring.) He had an average of 17L/100km now after the adjustement he has average of 8L/100km. His civic has 213000Km now the engine run perfectly and we can no longer listen to the Valve clapping when engine is cold 11-30-2012Registered!! Thread Starter

I personally haven't had to replace one in those years so I really can't say.....you'll have to find it and figure out if you can sneak it out of there or not. 09-09-2021Registered!!

I unplugged my spark plug wires from engine and connected them back in thinking that might of been the problem. I thought that fixed the problem cause for a couple months it didnt shut off on me. The other day, the car shut off again and check engine light turned on. I Waited about 5 or 6 minutes and car turned on and i drove about 15 miles and made it home with nothing wrong and no check engine light. I bought a scanner just incase car turned off again. Took it for a test drive and 9 miles into drive the check engine light turned on but car did not shut off. I turned on hazard lights pulled over, and checked car with the car scanner. It showed me a bad knock sensor code (p0325) turned around and drove home with no issues but check engine light stayed on this time and the check engine light has not turned off. Could the bad knock sensor have been the problem to cause my car to shut off or would it have anything with car turning off?

Engine warning light comes on. Error code is stored. Reduced engine power. Increased fuel consumption.
How do you test a knock sensor on a Honda Civic?1. With the knock sensor unplugged and using a digital volt ohmmeter (DVOM), check for 0.02V to 0.03V reference voltage from the ECM to the knock sensor. 2. Next use a scope and look for an AC voltage signal from the knock sensor when the engine rpm is increased.
