okay i have read other threads and found out what the codes mean, i reset the ecu with a screw driver i got 0303,0304, and 0407, one is front left 02 sensor, and one is knock sensor, one is crankshaft position, now what i would like to know how can i fix these sensors, can these be replaced without a mechanic, im broke so i think i should do it myself , the only thing i ever did on this nissan was bled the clutch line with the help of motorvate.ca. i was wondering if anyone can give me step by step instuctions with pictures if possible, that would be amazing, my car is also shaking weird on idle once i start the car, only happend after i reseted the ecu. thanks

 

and if anyone has these sensors for sale will be amazing too.

 

Yes, they're all fairly easy to replace (a little less so for the KS, if you don't know the tricks).

Personally I'd start off with the O2 and CKPS, leave the KS for later. Replace the first two, reset the codes, see if it comes back.

CKPS REF (0407/P1335) is bolted directly under the crank pulley, 2 minute R&R; 2 10mm head bolts and one harness connector.



It says POS, but that's the FSM for you; it's incorrect.

0303/P0150 is an easy fix as well, all you need is either an O2 sensor socket or a 22mm wrench (7/8" should work, a little loose). Undo the harness connector, R&R the O2 sensor itself, done.

 

yep...can be easily done.Search around on the org for parts or local auto parts store,read up on the how to's on the org or haynes manual and you should be set.

 

thank you guys i also had the car shaking at idel, but read the other threads and found i didn't turn the screw thing on the ecu all the way, fixed that, well thank you guys
