Hi,

I've got a bad TPS (I've tried to adjust it as described in the FAQ).
Does anyone have a better (i.e. less expensive) source
than Mazdatrix which wants $362.

Also, is there a way to remove the TPS without removing
the intake manifold? For some reason Mazda put a screw under
the manifold in a very awkward position. If it weren't for this,
replacing the TPS would be a 5-minute job.

Thanks for any advice.

There is a for sale section near the bottom of the main forum index. There are S5 TPSs for sale all the time there. Also, I do not see why you would have to remove the intake manifold to get the TPS off. I have both S4 and S5 cars that I have replaced the TPS on and never had to do it.

 

I've been driving my car with the TPS narrow range wire disconnected. It
run's good (no lurching) but I can now confirm that it will not pass CA smog.
I think it has to do with the fact that the air control valve isn't opening
and letting air into the cat. The HC readings were high, which means the
cat wasn't running hot enough. Does anyone have suggestions how to
get the ACV to open? Is it bad to keep it open all the time?

On my TPS there are two bolts holding it to the intake manifold
in the front and one screw underneath. I'll check the for
sale section for parts. Thanks.

It still is a 5 minute job. Its the 45 seconds of prep that your imagination has to achiev.
First, take a phillips head ph. 1 hex, you know, the bits that fit into your cordless drill. Then, get out a 6 mm end wrench. Put bit in vice, with phillips head down, leaving just enough hex showing to fit in box end. Tighten the shi t out of vice, put box end over the hex end, and one quick, swift blow with hammer, and wala, your new tool.

Now, I've solved the tool issue, its up to you to do the rest.

This sounds like a good idea, but it's not as easy as it sounds. The
screw is in tight and it is very difficult to apply upward pressure
to keep the screw head in the screw while trying to turn it.
Have you actually done this? If there was a bolt instead of a screw
it would be much easier.

Ok, you can do it. Why would I have made a special tool to take that screw out and then not actually use it? Use some smarts bro. If you made the tool correctly, use a long flat-head screw driver and jam the phillips-head into the screw, like pry up on it. If it is too tight, then put another box end of a wrench on the tool, and use is for leverage. Its easy.
