Ok I already did a search... And Found nothing that I could use..... I know the tps sensor reads, 0.5V closed and 4.5V wot. So being mine. reads 0.5V closed and 9.5V wot. So my dumb question of the day is do i have a bad tps. Or is there any other way to tell besides the volt meter.....

 

An oscilloscope or scan tool are the best things I've used when checking sensors but they're expensive. Just backprobe using paper clips on the connector unless you have special clips and see if it makes an analog signal.

 

Wow 9.5 volt thats weird considering its only supplied with 5.0 volts,how many volt are comming from the ecu?

 

I have know clue.... Why is that really odd. Well How can I check the volts from the ecu???? And Would it be better just to replace and get a new one.

What year is the car?

 

All sensors get a supply voltage of 5v and that's the most from the PCM.

 

95 civic ex with a b16a2 and p30 ecu.. but the weirdest thing is that when I had my vafc installed less than a week ago it read around .5v closed and 4.7v wot so what could have changed.

It should be a yellow & blue wire at the tps plug that should have 5 volts with the key on. I'm looking at a book for a different year so the color may be different, if you can tell me the color of your wires it would be easyer.

 

I know it has a red wire to the middle. And thats what i checked the voltage on.. But as you reffered to only 2 wires to the tps. or should there be 3 to the tps

 

I can go check the wires when I go on break. and run back to tell you. which would make it a little easier

 

Theres 3 wires the green/blue is ground,your middle wire in the plug is your signal back to the ECU and the other wire witch is yellow/blue should have no more than 5 volts with the key on at all times.

 

Weird here are my wires from left to right. green/white, red/blue and yellow/white...

 

Is it odd that the wire colors are different form the one's you said.

 

Like I said the book I have is for a different year colors will be similer. your yellow/white is the one that should have 5 volts from the ecu so just test that wire at the tps plug and it should have no more than 5Volts,if it does you should start by taking your AFC off the car,and repeat test.

 

Ok i'll do that and i'll see what happen's thanks for the info. But the vafc is already taken out.

 

You mite want to check to make sure you don't have any bare wire being exposed from the AFC removel.

 

Well i did tape any exposed wires form the removal but if it read fine before i took out the vafc and reads like **** now I should probably recheck.....
