Use a multimeter

Um, im trying to remember back to when i got my engine converted so i cant remember the exact resistances between the
poles. I think u should get something like 0.5-3.75Kohm in a linear progression as u turn the TPS gang. Measure the left pole and centre, then the right pole an centre. The values should mirror eachother. Hope this helps

For EL:Voltage at ECU terminal 47 for closed throttle 0.55 to 0.85 volts.
Wide open throttle 4.0 to 4.5 volts. Resistance between A and B terminals (top 2) terminals 500 ohms throttle open, 3000 ohms throttle closed. % volts between two outside tps terminals with ignition on.

Same for EF but ECU terminal in 89 not 47.

What car is it you have?
