What should the throttle position voltage at idle in a 1999 Saturn?

In a 1999 Saturn, the throttle position sensor (TPS) voltage at idle should typically be around 0.5 to 0.8 volts. This range indicates that the throttle is closed and the engine is idling properly. If the voltage is significantly outside this range, it may suggest a faulty TPS or an issue with the throttle body. Always refer to the specific service manual for precise specifications.
