Hello Everyone,

I got these codes a while back

P0325- Knock Sensor 1 Circuit Malfunction (Bank 1)
P0102- Mass or Volume Air Flow Circuit Low Input

and just curious what might cause these. Does the first one mean my knock sensor has to be replaced? I've been trying to find a diagram of where it is but I can't seem to find it for the life of me >.<. For the second code, could it be a bad sensor or something else?

Thank for any help!

I'd clean the MAF sensor and clear the codes and see what happens, if it continues replace the MAF, i'd think that that may mess up your cars AFR and cause slight KR tripping the knock sensor.

thats sounds like to me maybe a blockage at your air cleaner maybe try seeing if theres stuff blocking your filter if not try cleaning your sensor it might have dirt blocking the correct reading

Thanks Guys!

I cleaned the MAF as well as the filter (Which fixed that) and had to replace the knock sensor. Turns out the knock sensor some how disconnected from the connection clip...not sure how it happened but easy enough fix.

some times it is just simple things.......
and that is why the simple things should always be checked when you have issues.
