Default 24, 41, 52 engine codes

Hey guys so I got codes 24, 41, 52 that come up at the same time. I already know what the codes mean and I already done the knock sensor rewire a few months back. So could one thing cause all these codes to come up at the same time like the air flow temp sensor or the throttle position sensor went up. The car still runs fine and idles fine also at about 700-800 RPMs. But it does feel like it lacking some power not much. Guess that from being in safe mode. The car is a 89 7mge.

They're unrelated... start with checking grounds for the codes 41 and 24 if you have already tested the AFM and the TPS. As for the knock sensor, replace it... you can use the knock sensor off of a lot of same year Toyotas so hit a salvage yard and collect a handful of them for $10.

Ok I tested the air flow meter. Between e2-vs I got about 350ohms then between e2-vc I got 280ohms. Then E2-tha I got nothing when I'm suppose to get a Reading depending on the Degrees outside I guess. Then e1-fc I got infinity. I tested the way the tsrm-online show.
