No a knock sensor can not make a misfire. Check the coils, plugs and fuel pressure .The random misfires are cause the knock sensor to throw the code.

2003 2500hd rough idle and hesitation o2 sensor and multiple cylinder misfire codes but seems to run ok under normal driving


Sounds like a defective knock sensor. These bring on multiple misfire codes with little change to performance. Check your oil level too, this can make knock detection codes come on unnecessarily. Hope this helped...

Will a bad knock sensor cause a misfire. car is missing change the plugs no help codes are misfire and knock senser sometimes a #2 o2 sensor. 1999 maxima thanks for your help.


A Bad Knock Sensor will not cause a misfire, unless the advance is off due to a faulty Knock Sensor. The O2 Sensor will cause a random misfire.

Good luck on this repair.

Acts like the knock sensor is bad. engine misfire on multiple cylinders.


The knock sensor will give you poor accelleration only when trying to drive at first when cold & the same when the engine is hot. If you have a misfire it will be something else causing that. A weak coil, Timing belt, a waek ignition module, & so on.

1996 Nissan Maxima 2.5 V6 Engine Knock sensor The engine runs fine; but it sets off 2 codes knock sensor & ignition. Just this week had the plug wire and knock sensor changed, new. Still the same code...


The knock sensor is a major pain in the a..s to change I would suggest taking it to a reputable shop for a second opinion to see if they realy performed the work. Also with OBD11 (2) diagnostics if you have multiple misfires its not the wires its something else, also if you got a code for a misfire it would be specific as to which cylinder is misfiring. My best guess would be to get your coil checked.
