DC350

I've read all the follow ups and the do it yourself help. But i warm the car up. Turn it off, out the key into the on position, put the probes negative into the black wire. and the red into the opposite side. green wire. I turn the multimeter to Ohms 1x and it reads O ohms....whats goin on? Any help would be muchly appreciated! I can push down on the throttle. adjust the screw, and nothin happens on the multimeter! Please Help! Does the car need to be on?

Cheers

sounds like you are not getting a good connection with your probes. Also, did you touch the probes together to make sure the multimeter is working?

I have used both methods, i think the test light method is much easier. It does not tell you if your tps is bad, but at least you know the ecu is getting the right signal from the tps at idle.

Just curious, why did you touch the TPS to begin with?

DC350

Because i have some major hesitations and..while i'm driving it's like the car just....stops making power.

The multimeter works fine...

Have you checked all you ground wires? AFM plugged in nice and tight as well?

That won't even matter. You don't even need to have the key turned on if you are just going to be checking the resistance of the tps, you can do it with the tps off the car. Grounds, etc. won't matter with that method. There are 3 wires on the TPS connector, two vertical and one horizontal. Try the other vertical one. If that doesn't work and you are sure you are checking RESISTANCE not voltage, then you have no resistance where you should have some and you are most likely going to need a new TPS.

Also, is it reading 0 ohms or infinite resistance? Some meters behave differently (mine says 0.L when the resistance is too high). Touch the two probes together, that's 0 resistance, the other is infinite (sorry if this is basic - just making sure).

For the hesitation problem, do check your grounds and connections, hoses.

I'll get right on that. I'll let you know how it turns out

I meant checked the grounds and AFM to cure his hesitation problem not to check his TPS. If his TPS went bad no amount of adjustment is going to cure the problem, and a TPS doesnt just lose its adjustment and actually almost never needs to be touched to begin with. Once people start messing with this crap thinking they can get the car running better, they usually make it worse. Chances are there is some other problem and the TPS probably has nothing to do with it.

DC350

what other problems are you suggesting?


This is my 1000th post guys!

Right on! I'm going to check the TPS more. Its not the usual hesitation problem. Its all throughout the power band whenever.

I love you guys BTW! Its my centimental saying for my 1000th post. Couldn't be here without you!

They best place to check the TPS is at the ECU. The connections at the TPS are probably corroded, and it takes into account the resistance of the wiring.

Just look at the wiring diagram and find which wires are for the TPS

I'll just clean em all. thanks for all the Help. Nice cars! My dad lives in whiterock!

Rob xx 7,

I realized you meant that after I wrote that. That's why I put that last line in there, sorry 'bout that.

Its quite ok, usually people mis-understand others when dealing over the internet.
