You can read them all from the puter to the component connector to verity wires are fine. The tps and inlet temp have different readings in different conditions. I use my haynes manual to check mine. Knock sensor has a shielded wire that if shorted could cause a problem, just check all connections first though, last time I had some codes the TPS plug was hanging on half way.
on the pics the THA-E2 is you inlet air temp reading.
