Freelander 02 code P0332 P0327 fix

[Alarmin]

How do I fix Code P0327 and P0332. Tried to reset it did not work, Truck has 111000 miles. Do I need to replace sensors? Help

Welcome to the forum.... Let me move this to the technical section you will get better responses there.

Those are indicating that both knock sensors are failing, one on each head.
I imagine that your performance has fallen off and your engine may be pinning on whatever octane you are burning.

Thanks, the motor has a slight ping you really have to listen for it. I will try replacing sensors.

I don't think they are cheap, and am surprised they both went out at once. Before throwing money at it, have someone scan or read the signals from both sensors to verify they are bad.
