When does a knock sensor need to be replaced?

When does a knock sensor need to be replaced?

Is there a bad knock sensor on my computer?

Perhaps you could report the specific code. Note that NONE of these say “bad knock sensor” – the computer is clueless about the actual condition of the sensor itself. Its just a box of wires hooked by wires to other wires. That’s about it. I doubt your symptoms are from that though. You should troubleshoot the speed sensor code.

Can a crank and cam sensor be replaced?

I replaced both the cam and crank sensor and car still will not start but if I unplug the crank sensor it starts up and runs like crap. I can not figure out what to do next. My car has 91000 miles. My car has an automatic transmission. You should check to see if your vehicle has jumped timing.

Can a faulty knock sensor cause a check engine light to come on?

The faulty knock sensor will not cause the Check Engine light to come on nor will it cause the driveability symptoms you describe. The cost for knock sensor replacement is that high because it involves removing the upper and lower intake manifolds for access.

Can a defective knowck sensor cause chugging power?

While it is theoretically possible for a defective knowck sensor to cause an unwanted ignition retardation and poor power, I don’t believe it can cause chugging. A knock sensor is a piezoelectric device tuned to a specific frequency to detect preignition pulses.
