I'd say clear codes and see if they come back,
You might try disconnecting and reconnecting the connector to the TPS, sometimes just doing that will clean a borderline contact enough.

What issues are you having?

 

I would say the 123 code is a problem, unless someone has tampered with the throttle stop as a way to adjust idle. Sometimes, when the slug buildup in the throttle body causes the throttle to stick, instead of cleanning the throttle body, someone may turn the throttle stop screw just a bit and that will raise the tp sensor reading above idle to part throttle. That will set the code.
As for the 332 code, do you get this on an KOER test? If so, check the egr vac regulator on a KOER test to see if you are getting vacuum demand to the egr valve. If not, the regulator is the problem, if so, does the valve open? That will tell you if the valve or sensor is the problem.

 

If you plan on keeping this vehicle invest in a copy of "How to Understand, Service and Modify Ford Fuel Injection & Electronic Engine Control" by Charles O. Probst, SAE. It is about $20 at Amazon. Most of the sensors are designed for a maximum voltage of 5 volts, some are up to 8 volts. The TPS range for the 93 Ford products is 0.6 volts to 4.5 volts (approximately), so that the computer will "code" when the voltage reading is over or under the voltage range programmed into it (computer). As suggested above disconnect and reconnect the TPS. This can sometimes reestablish a good connection. Look for any corrosion in the connection and also look for any loose pins or wires. Given the age of the vehicle and likely high milage I would replace the TPS, but if you want to do a backprobe test (KOEO= KEY OFF ENGINE OFF) between the TPS wire (gray/white), and the return signal wire (Gray /red) look for voltage readings between 0 and 5 volts while you rotate the TPS through full range, that is closed throttle to full open throttle. The voltage referance test is done by backprobing the voltage refference wire Brown/white, and the signal return wire gray red. This is done with the KOEO and the TPS wire connector disconnected (key off, waite 10 seconds, disconnect TPS sensor connector, probe between the aforementioned wires at the harness connector. Expect 4 to 6 volts, if not check the voltage refference circuitry and wiring.

 

hey coloradohoosier.....what was the issue with the 998 code? I get the same thing when testing my 92 ranger.
