Question : AM I right to say that a new engine will not ping/knock
if it has an oxygen sensor that automatically controls air/ fuel mixture and
knocking sensor that prevents engine from pinging/knocking by automatically adjusting the timing.
If it still pings, what is the problem?
I am using RON97.
It is the knock sensor that prevents
If you get 'pinging', you should get
the knock sensor checked as either that is
faulty or there is a harness problem.
If the O2 sensor is at fault, it will be
indicated as a fault in the EFI system and
on doing a system check, you will be able to identify the problem.
Actually, it is quite rare for the knock sensor to give problems as it is
not in contact with any product of combustion, unlike the O2 sensor.
