We are talking about a KA right?

Knock sensors are quite commonly bad as the cars are 23-27 years old now. I've always replaced them on any 240 I worked on at any time it was convenient, with or without a code, and absolutely ALWAYS before I swapped a motor in. They're expensive as hell from the dealer too. DO NOT get ANYTHING other than an OE Nissan knock sensor EVER! I don't fucking care how expensive it is. The aftermarket ones are complete crap and they're a TOTAL PITA to get to.

As for the coolant temp sensor code, also very common. The temp sensors go bad and the connectors get all corroded and need to be replaced.
