Sounds like you looked up the codes, is there a troubleshooting guide in a manual for your model year? I know I have one for mine, but I have a 99.
You know the throttle position is good, and the other one - top dead center?? - that's a sensor on the crankshaft ... it looks like an wiring problem. Need a service manual for your year - try this forum - and locate the diagram for the tps and follow the wires down to the ECU, same for the tdc.
Was there any work done on the car lately, or in other words how's this come about?
Let us know - always like feedback.

I'm pretty sure in 91 that all timing sensors are located in the distributor.
CKP = crankshaft position
CYP = cylinder position
TDC = top-dead-center

Those are not replacable by themselves, you have to buy a new distributor. But you CAN check for loose/dirty/corroded pins in the multi-wire connectors right there at the distributor.
