dude, they're using an npn transistor to represent a whole ECU
anyway, to me the symbol says "potentiometer" but may or may not be exactly that, or just something kinda like that, or maybe some abstract analog sensor. I don't think you mentioned what code you were getting and what it meant
you could try hooking up a 10k linear pot of your choice and seeing what the ECU has to say about it. start at the brown end and work your way up slowly until the ECU shuts up, then temporarily secure it somewhere and try her on the road. NB driveability may suffer
to go further, you'll need to know specs like the output voltage range and how it corresponds to the pedal position (maybe a scan tool or ELM-type interface will help reveal that information), and then design a replacement variable voltage source based on something about the pedal position that you can adequately observe, anything from a microcontroller sensing the piston position capacitively at the cylinder, to a resistor/LDR by the pedal

Rat Shack used to sell Pic related to keep from overheating parts and wires when you soldered them. silicone is great for test leads and HV, terrible for general chassis wiring
