KNOCK SENSOR REPLACEMENT

2002 Nissan Maxima

Engine Performance problem
2002 Nissan Maxima 6 cyl Two Wheel Drive Automatic 105K miles

Hi Sir/Madam,

I have a 2002 Nissan Maxima SE(3.5L SFI DOHC 6cyl). The " Service Engine Soon" light is always on. The mechanic told me that it was caused by the broken knock sensor. The vehicle has 105K miles and I think is out of warranty. Where should I repair it (my zip code is 70112)? Could you please give me some suggestions? Approximately how much will it cost? Thank you very much!

I do not know your location but I can give you an average estimate based on a $70/hour labor rate and part price quote from the dealer. ..

Thanks, that's expensive. Can I just buy the OEM version of it and have some mechnician replace it for me? I don't know whether there are some repair shops that can do this for customers using customers' own parts.

The knock sensor is located under the intake manifold.

Yeah, a local shop can do it for you. Any local repair shop will use your own part you bring in. Just go to a local part store (AutoZone, Advance Auto Parts etc.) And order the knock sensor. Then take the sensor to a local reputable repair shop and ask them how much they charge to replace it. The sensor will be around $125 at part stores compared to the nearly $200 at the dealer.
