Got Codes?

h8z2luze · 08-19-2006, 06:05 AM

I got 3 codes in my 89 n/t supra, 24 - Intake Air Tempature Sensor Signal 41 - Throttle Position Sensor Signal and 52 - Knock Sensor Signal. What do you think of the codes? TIA.

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.

Cool thanks, I will check that out. I know the connections are good thats the first thing I checked.

Are you having running problems???

If not, then I would clear the codes and drive it awhile, then check for codes again.

Yea, it idles like crap. Up and down up and down and when I come to a stop it usually dies unless I keep it going.

This poor idle thing seems to happen to alot of supras. There must be some "usual" cause. I certainly have read a lot of complaints like this.
