Calais L4-151 2.5L VIN U TBI (1989)
Throttle Position Sensor: Electrical Specifications
Voltage 0.20 - 1.25 V
Note: TPS voltage is checked at idle. The maximum TPS
reading at idle is 1.25 volts.
0.33 - 1.33 V
Note: 1991 models only. TPS voltage is checked at idle.
The maximum TPS reading, at idle, is 1.33 volts. The TPS
has an auto zeroing feature. If the voltage reading is
within the range of about 0.33 to 1.33 volts, the ECM
will use that value as closed throttle. If the voltage
reading is out of the auto zero range at closed throttle,
check for a binding throttle cable or damaged linkage.
