Vibrations/Fault codes

My car has massive vibrations, throughout steering, peddles and chassis. Recently had new discs etc fitted. All seems fine with wheels,tyres,suspension and the brakes. Thought at first was whilst on the move, at high speed felt like the front wheels were going to fly off. Then realised also shaking whilst stationary. All engine mounts seem ok too. So assumed engine problem, as also slight misfire, plugged in. and the following appeared.
325 Knock sensor non compliance with pollutions.
322 Knock sensor abnormal voltage.
389 vehicle speed information.
P03225 Knock sensor 1 circuit.
Have had codes cleared, car is a bit better, but what is the cause ????????
Spark plugs ?? ( Changed 10 months ago- 12,000 miles).
Coil pack ??
Knock sensor and or wiring fault ??
Any help would be very much appreciated.
 
I would prob say wiring fault to knock sensor just by the code 322 abnormal voltage! Would get a decent electrician to check the wiring.
 
remove the plug on the sensor - wd40 connections - put it back and see how it is...
 
Compression test fine. £50.00 lighter after fitting new knock sensor ( pinking sensor ). Has cured the vibrations, but....................
