My car has a manual transmission.

As you may know a knock sensor may fail for any of the following reasons:

  • The knock sensor is faulty and needs to be replaced
  • There is a wiring open/short/fault in the knock sensor circuit
  • The PCM/ECM has failed

Any of the above could potentially cause a misfire. The knock sensor should be located under the intake manifold between cylinders #1 and 2.
