Is there a replacement interval for a knock sensor?
There is no replacement interval for a knock sensor. Knock sensors usually set a code that turns the service engine soon/check engine light on when they go bad to alert the driver there is a problem. Knock sensors could last for the life of an engine, and some go out at 50k miles.
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.
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.
