Following up on my TPS problem... Thank you for the help. A new mass air flow sensor fixed it. So anyone searching these forums concerning the same problem: If you are getting a TPS fault code, but the TPS is good and the TPS circuit is good, then REPLACE THE MAF SENSOR. It runs...

MrShorty, thanks for directing me to Glacier's posts on scanners and code readers. That thread was very informative. I currently only have a Ford code reader that displays numbers. I tried cheaper flashing ones, but got tired of counting flashes. I used to own a 89 Camaro and only used a...

Measured at the PCM today, the signal voltage at the PCM (small hole through the wiring to check the voltages) and I get the same measurements (throttle open and closed). Could my PCM be malfunctioning? It seems to be getting the right voltages, but it may not be registering it correctly. I...

I did reset the computer (continuous memory codes) several different times--with the code reader; also by disconnecting the negative on the battery for at least 10 minutes, sometimes over 30 minutes, and overnight once. MAF? I know MAF's and PCM's are close in price. I wish I knew which...

According the limited wiring diagram I have, it looks like 60 is ground for the PCM. I'm thinking there is a possibility the signal voltage is not making it back to the PCM, so that wire might have an open somewhere along the way. I believe that one goes to 47. If so, I would have to run a wire...

I am having that same surging problem and the fault codes even says it's the TPS, but I have replaced it with 3 TPS' (2 from Auto Zone and 1 from Advanced Auto) just out of frustration, but it has been no help. The voltages from the connection and the TPS all seem to be pretty good, so I don't...

Still having problems... I'm still working this problem, but other things I have been working on took priority, but back to this is really frustrating issue. With the connection disconnected from the TPS, and using a digital voltmeter, positive probe on the reference voltage terminal of the...

I think it is worth keeping too. And about those window repairs though, a few months ago I had the same problem. I replaced the power motors on the front two doors and they work great. You can find those motors brand new on ebay ranging for around $50 or so each, depending on who you get them...

Today, I have tried 3 different Throttle Position sensors (and 2 different brands) on my 94 Explorer XLT, but I still am still having problems. The fault code is still indicating 122 (Throttle Position sensor below minimum voltage), and it also runs like it needs a new TP sensor. I have...

For 6 bucks, at the Ford dealership here, I got a set of four of those (they only come in sets of four). I just picked them up yesterday. I had to drill out one of the old ones.
