Hi there, can anyone help on telling me how the P0325 or knock sensor code affect the performance of my Quest? Thanks in advance.
The ECU will not advance ignition timing, therefore the engine is operating in limped mode. Vehicle will feel like lack of power. If you continue to drive the vehicle in this condition, this will cause the engine to run fuel rich condition. And this will contaminate O2 sensors, combustion chambers and cat converter.
Can anyone help us with a detailed location of the knock sensor on a 1999 Nissan Quest? We got one answer from anther website and it was not where they said it would be and we are playing hell trying to find it. Any help would be greatly appreciated.
Here you go:
The photos were taken on a Maxima engine, but basically it’s the same engine block as Quest. Quest uses single overhead engine, where as for 94 & up Maxima uses DOHC.
Because of different head design, Quest’s intake manifold has coolant lines underneath it and water jacket/channel for better heat transfer. The knock sensor can not be accessed unless you remove the intake manifold assembly. Maxima is accessible without removing the intake manifold.
