Question

hi, my Nissan was showing P0325 and now showing P0172 is this meaning two different problems? For 2001 Nissan Skyline 2.5L

Answer 1

p0325 is a knock sensor code but that will come on with another code, so fix p0172 first.

possible causes:

- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Faulty Mass Air Flow (MAF) sensor
