Still doesn't start..??
OK.. maybe.. I missed something, Relocated new knock sensor/Harness as pictured, found the conduit and found a black shielded white wire wrapped by a flat gray wire, kind of like a coax cable, cut and peeled back the gray wrapped wire and twisted it into a long one piece strand of wire,
next I cut the white wire and connected it to the wiring harness, I noticed pictures of the "old" sensors had only One wire attached the #1 side. Checked my codes on the code reader and everything ..PASSED Sill can't get my 2000 Nissan frontier V6 to start...ANY suggestions??? |

The other wire is a ground and unnecessary as the knock sensor grounds itself when attached with a bolt to the manifold.
The sensor has nothing to do with starting or not but rather is more an emissions related issue. You need fire and gas to start and run. Pull and plug wire and ground an old plug while someone cranks it over to check for spark. If you have spark then check for gas by unbolting an injector and again using a container, cranking it should pump gas. If you have fire and gas, it's a timing issue with gas and fire out of sync. Good luck. |

Fuel to Cylinders OK...NO Spark
Thanks Again Chartrain, Fuel is going to the Cylinders but no spark to the Plugs..I just installed New plugs so they aren't the problem. I'm not a mechanic, sooo..what might be the cause..?
What happened is while I was driving the truck..it stalled at a red light..an would NOT restart. I happened to have my OBDII with me and the code reader code said I had a malfunctioning "Knock Sensor", relocated it with a New Sensor & Harness (rather easy to do), connected the wires (after finally finding them) and rechecke with the code reader...it said "PASS". But now as you stated I checked fuel/spark. I could smell the fuel on the #1 spark plug I removed.....I checked the #1 location on the Distributor with a lighted probe designed to check spark...Nothing.! Trucks battery recharged to 100%..so what might be the cause..any & all help appreciated....!!! |

I have a 2004 Frontier with the 3.3 v6 in it and am now getting the PO328 code for the knock sensor. Since this forum is rather old, can anyone tell me what I need to complete this relocation on my truck? I'm new to the forum, so forgive my ignorance, and thank you.

I am not able to upload pictures of it, but it is on the back of the intake toward the firewall. It has 1 hose coming off and 2 #12 bolts. If you are looking between the engine and firewall you can't miss it. If you have small hands you can get it unplugged without taking off the hose and plate.

Works awesome, just got back home to Vegas from San Diego. Next weekend I'm towing my 28foot car hauler and drift/race car to willow springs for ASB13. 19mpg highway mileage. Doesn't get any better than that.

I performed the relocation process, before I had two codes for the Knock sensor, high voltage and low voltage codes.. After doing the relocation I have High voltage (p0328), is it possible that it is the ground to the sensor causing it, since it grounds to the intake manifold which is aluminum?
Anyway, i plan to hookup a wire directly to the negative bat post and the sensor, just to make sure there is no ground problem will post an update when I am done.. I also have a code for my catalytic converter, BUT I was told by someone else who knows these trucks well, that the code is most likel caused by a crack in the y-pipe just below the cat.. removing the pipe, welding the crack should fix it, or replacing the pipe for 900$.. lol I can't believe though that nissan gets away with having this many problems with almost all the cars/trucks with this engine and do not even create a TBS for it.. Makes me miss the quality of toyota... |

Did the Knock Sensor relocation about 3 weeks ago. Have the Knock Sensor for my Xterra and couldn't find the harness for it. However, I bought another that came with harness (for an Xterra XE V6, 2.4L) install this one instead cause the harness would not fit the KS that fits my SE V6 3.3L. Worked fine, but my engine light came on again 3 weeks later. Is it because the KS is only for an XE 2.4L rather than the SE 3.3L? If so, where can I find the harness for the KS that fits my Xterra. It has been really impossible to find this harness. However, I've notice other people are using a KS for a Nissan Maxima. What is the year of the maxima that I can use the KS that will fit my 2004 Xterra SE V6 3.3L? |

2004 Xterra SE V6 3.3L
Quote:
Now 3 weeks later light on again, but 0420,0420p, cleared them out, it reads "NO CODES AGAIN" if my catalytic was bad I would have not passed the smog test few days after. Again, is the KS for an Xterra XE 2.4L incompatible, does it truly need to be for an SE 3.3L? |
