What does Jaguar OBD ll PO333 error code indicate?

Answer 1

"Knock Sensor 2 Circuit High Input (Bank 2)"

A knock sensor prevents the air-fuel mixture in your cylinders from igniting before the spark plug goes off. Knocking usually occurs when you have a high-compression engine using low-grade gasoline. Always use the manufacturer-recommended grade of gasoline. Since you're only receiving the knock sensor code for the second bank of cylinders, most likely your knock sensor wiring or sensor is malfunctioning. Engine "knocking" sounds like metallic pings coming from the engine. If you don't hear that, then it's just your sensor.

Answer 2

Knock sensor 2 circuit high input, indicates voltage above 4.5 volts on the side of the engine opposite the number one cylinder
