Ok Ive read all the threads on setting the tps voltage, adn I have a new problem not yet found in previous threads. You set tps voltage at .54 +/- .075 volts right? OK I only have .508 volts coming out of the wiring... and im getting a code 22 tps low voltage... I replaced the tps, but I cannot turn the sensor far enough forward to make any difference because i dont have .54 volts coming out to start with.... is this normal????
