1990 2.3L Throttle position sensor
My son's Ranger has the dreaded check engine light. I took it to Autozone and did a scan on it. The result was "low voltage from throttle position sensor". I bought the TPS, and when I refered to the Haynes Manual it said that the TPS should not be replaced by a "home mechanic" because it needed special calibration after installation.
Is this accurate? I recall replacing the TPS in mid 80's Buicks (when I was a tech) and it was pretty much plug and play. Of course, my memmory could be failing me.

The mean voltage on the TPS should not exeed 1vdc closed (>1vdc signals the computer that the throttle has opened) , optimum set at .96vdc.
That would be the only "calibration" that would/might be made. Go ahead and replace it yourself.
