Thread: annoying problems,need advice

i moved this from the b14 section to here
Alright,so ive been having a few quirks with my car and i need some direction.im a tech,but diagnostics arent my strong point,only been doin this for about 2 years now.so,my cel came on,i scanned it,and had a knock sensor code.i replaced the knock sensor,and twop days later the same code came back,i think it was po325,ks circuit malfunction.not sure if i should try probing the sensor,or a relay or wat.
the other problem.my speedo died. i replaced the clutch,and after i had the tranny back in the speedo was working for about 20 minutes,i leave the gas station and all of a sudden it falls to zero and hasnt worked since.hoping not to have to pull that sensor,it seems pretty stuck in there,and theres two identical sensors in the tranny.are they both speed sensors?this seems strange cuz i dont have the lsd.anyone whos had this problem i would really appreciate any suggestions.

nissan knock sensors are extremlly durable the conectors suk and the wire tends to break down some were between the sensor and ecm.idk why excep that its a sheilded wire that must have a diff quality than the other wires in the engine harness.

1st replace connector
if code returns
2nd run new wire to ecm

Cool,thank you
