Ford tells me that there are 2 parts to the TPS in the CPI throttle body, an outer part and a inner part. Gregorys manual only refers to the outer part which I have tested with a multimeter as per manual and its ok, (Its just a variable resistor). My question is that the error code 63(low TPS signal) is coming up in the memory codes and not a constant fault. What TPS should I replace as they are $100 each from ford, any suggestions????
