I have a 1996 lexus lx450. Engine check light on showing bank sensors codes
Bank one and bank two
PO 325
PO 330.
This truck comes with a factory TRD supercharger.
Can anyone tell me what that might be?? I fixed all air leaks exhaust manifold gasket etc.
This is a kind of old post, so I'm going to post for other peoples' benefit. First, you need to view knock counts vs timing advance in real time and see if the knock is real or phantom. Knock on both sensors is strange; usually that is not indicative of a sensor failure, unless the sensors are aftermarket. There is a heightened possibility of phantom knock detection with aftermarket sensors. If the sensors are OE, it automatically points towards harness, ecu, or mechanical engine problems. Hopefully this helps someone else out.
