I have a 95 Civic coupe with a JDM H22a swap and im getting a Code 7 CEL - Throttle Position Sensor. I checked the voltage at the sensor and its reading .004v with the throttle closed and 3.3v at wide open throttle. I've researched and found it should be .4-.5 closed and 4.5-5 at WOT. I adjsuted the TPS but the voltage only drops lower. The car idle's and runs fine, but it keeps throwing the CEL, does the TPS need replaced because of the lower voltage? Is it starting to go bad?
