Throttle Position (TP) Sensor

WARNING: This page is about a different car, the 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, and 2003 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: TP sensor is not adjustable. For further testing procedures, perform TP sensor related diagnostic test. See appropriate SELF-DIAGNOSTICS article.

⁽¹⁾	Voltage range is from idle to wide open throttle.

⁽²⁾	The Powertrain Control Module (PCM) computes the Throttle Position (TP) from the TP sensor voltage input. The TP angle will auto zero to zero percent at idle when the TP voltage is below 0.90 volt. The TP angle will read 100 percent at Wide Open Throttle (WOT).

⁽³⁾	Scan Tool Range 0-100% or 0.00-5.00 volts. The voltage being monitored by the PCM on the TP sensor signal circuit.

⁽⁴⁾	Voltage ranges from 0.00-5.00 volts.
