Roadmaster Estate Wagon V8-305 5.0L (1991)
Throttle Position Sensor: Adjustments
The throttle position sensor is not adjustable. The normal closed throttle position voltage is between 0.40 and 1.25 volts, and normal wide open throttle
position voltage is approximately 5.0 volts. If these limits are not in specification, check for freedom of throttle movement, and accelerator pedal
interference from carpets and other obstructions. If the problem is not corrected, replace the TPS.
