CHeck engine light

OBD11 code is 325 and 153. Any help? 1999 Maxima. Thank you.

325 is knock sensor. 152 is Front O2 sensor Bank 2. Bank 2 is the front bank.

change the o2 sensor first, the knock sensor may be a piggy back code

Yup! My maxima was telling me knock sensor and o2 sensor as well. I saw a code reader on sale for $80. it was usually $230 so I got it. when I plugged it in it only said oxygen sensor and that the knock sensor checked out ok. You should go pick one up. a knock sensor or oxygen sensor both cost more than the code reader. its well worth it.

Thank you all for your answers. I'll change the O2 sensor first.Have a great day!
