I have a 240 and with the knock sensor unplugged it will still start so I would have to say no.
No it will not.
No. It only senses engine vibration/knock.
it shouldnt.
The knock sensor detects spark knock (ping) and sends that info to the ECM. The ECM makes timing adjustments to stop the ping.
No.
The knock sensor sends a voltage pulse to the computer whenever it detects the vibrations caused by metal, such as the conditions caused by the spark knock. When the knock sensor sends a voltage pulse, the computer retards the timingin an effort to stop the spark knock.
NO.
No, That part will not shut the engine down
No. The knock sensor alerts you to the fact that there is an engine vibration that needs attention. Mine has been awaiting replacement for six months.
Might be a sensor. Something like this happened to me and it was a sensor that had to be changed.
check the switch on the top of the brake pedal.
It can, but not always.
