You can drive the car but if the engine should ping (knock) under load, the knock sensor won't be able to tell the computer to retard the timing. Excessive pinging can damage internal engine parts.


Have a 97 Olds 88 replaced MAP sensor and new gaskets for coolant leak everything was great. Now about 250 miles later the engine has a loud ticking knocking noise. Would this be a knock sensor?

The knock sensor is exactly what it says. It senses any knock or ticking in the engine and retards the timing. The knock sensor is not the problem, the knocking is. Go to a repair shop and have it diagnosed.

95 Villager is stalling on the go but when restarted goes good for some time Code says knock sensor 34 Is it really a knock sensor problem How do you change it Where exactly is it located?

Also you can remove the front oxgyen sensor and drive it. If the problem goes away it is probably your catalytic converter. The dealer replaced mine because the van has less than 80000 miles on it.I have a 2000 and I tried to get around replacing the knock sensor. I replaced fuel injectors, wires, plugs, distributor and some other parts. All this helped, but van still lose power and surges after engine hot. I been told after all this that the knock sensor retards timing and causes the fuel not to burn as it should. It not only senses knock, but is a protective device for the engine. I just purchased one on eBay for $65 and will install later this week. Should have replaced it when I first got the code.AnswerThat does not sound like a knock sensor problem. the knock sensor senses "knocks" in the engine and retards the timing accordingly. The knock sensor should not affect stalling, the problems are probably not related. The knock sensor itself is located under the lower manifold. It is a lot of fun to get to.
