Code 22. Throttle Position sensor voltage too low...anybody ever get this?
I just got my car off the jackstands. I have noticed that my Average MPG seems to have dipped way low (indicates about 13.2 city MPG), but it is possible that my enthusiastic driving and custom Ed Wright chip might have something to do with that.
I scanned the car with my scan tool, and I get a Code 22 THrottle Position Sensor Circuit - signal voltage low. When scanning in real time mode I get a range of voltages from .6 (no throttle) to 4.07 volts at full throttle. The throttle position value, read from the scan tool, goes from 0 (no throttle) to 99% at WOT .
I am wondering if I need to replace my Throttle position sensor? Also, could this be causing my bad fuel economy? Anyone else have any experiences with this?

replace the TPS sensor
see whats up with the mileage then, if its still bad it could indicate a bad O2 sensor

nah. O2 sensors seem ok. In the sense they fluctuate between about 100 and 900 mV.
Although my left block learn has been traditionally under 128. Still havent got that one figured out. Its at about 110.
Would a vacuum leak cause my block learn to be low I wonder? I say that because I have hooked up my opti-spark vacuum source (upgraded to the vented style) to a part of the plenum that is on the drivers (left) side.
