This is just the information I'm looking for!
Any idea if a bad RPM sensor would show up as a bad TPS sensor? I've adjusted the TPS sensor on my son's 93 F250 every which way I could find and nothing seems to help. We replaced the TPS and adjusted the new one within the range of 1.2v to 4.6v (idle to full throttle) with no joy. Then we set it at 1800 ohms +/- 50 ohms at idle position (based on something he found on the internet). Transmission still snatches your teeth out when it shifts. I'm getting the same codes as you.....23 and 14. I ohmmed out the RPM sensor and got nothing at all...I think the wires might be broken where they come out of the sensor. I'll check it your way with the meter set on volts tomorrow to see what that gives.
Thanks for all the info!
