i just reinstalled my factory throttle body on my 2000 civic si, in my haynes book it say the tps sensor votage should be around .5v closed throttle and 4.5v on 100% throttle, well mine is .53v closed and 4.6v 100% is that enough of a differnece to through my cel.

 

no

 

Could TPS be bad with no CEL, or anything else for that matter?

 

that should be well within what the ecu can correct for.

 

I thought it was .5 closed and 5 open?

 

the haynes book says .5 and 4.5 and i checked the voltage on my friends sh and it was around .5 and 4.5, it's suposed to be around 5v at the fire wall conector going to the sensor.
