What is the voltage level the TPS should be at on an h22? What about h23?

I need to know because THere's something different about the ECU(13 and p14) but i don't know what.

I'm still having the same bogging issue as before - i'm really aiming towards my TPS...i will check the voltage later today....

Also what differences are there between the p13 and p14? Besides vtec - I can't do much to my car until i get it fixed -
Does the p28 have vtec?

When you check the voltage....where do you stick the prongs? Isn't there three wires to the tps?

 

bump

 

You check the TPS @ the signal wire. Voltage is .5V @ idle and 4.5V @ WOT.

I think I get like 5 minutes flate rate dio on this haha.

Or you could just swap the ECUs, you know whichever.

i am trying to test my tps voltage and what i dont undersatnd is how do you test the voltage when the connector is plugged in? i dont see any way to get the volt meter on bare wire to test it?? thanks for any and all help

 

straight shooter, upper-management written all over him..

yeah....I think I'm gonna have to disagree with you there, guys...Peter's been real flaky lately... keeps forgetting to put cover letters on his TPS reports...


just poke the prong into the back of the wire harness, unless I'm thinking of the wrong thing
put the black probe to any ground (engine mount ground is closest), or just to the body.. anywhere it's touching metal. then probe the wires one at a time with the red probe. one should show 0 or continuity (closed circuit) that's the ground for the TPS, one should be a power source (12v constant?) and the other one should be the wire that tells the ecu what's up... this one should be the one you're interested in.

I don't know for sure, I'm just guessing based on what I know about DC. This is what I would do

no idea for the ecu differences, not something I've done before.

You could use T-taps to do it, if you can't figure it out.

Also, I recommend actually grounding out the multimeter on the TPS's ground wire instead of a chassis ground; if there is more resistance along the ground path for the sensors, your reading may be slightly affected.

 

yeah the p28 has vtec, im running a modded p28

it has curred (or should i say masked) most of my boging problems exept for the one that occurs during the first 1000 or so rpms after the vtec engages
