Question about 2000 Toyota ECHO
Spec's on the TPS are?" Throttle position sensor"
Keep the ignition switch to ON engine OFF. Hook the scanner, diagnostic computer or Techstream and take the reading. With the throttle pedal fully released it should read the TP sensor value between 9.8% to 18%.
It is better to keep the value as close as to 9.8%. To adjust the TP sensor, loosen the two torx screws, and adjust the sensor to the desired value.

SOURCE: CEL Code 71, V-6 engine.
This code can mean no EGR flow is detected, manually open the valve and see if the engine starts to stall, if it doesn't you have a plugged EGR exhaust gas passage

Throttle Position Sensor
The 3 wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the throttle blade.
The TPS is a 3wire variable resistor that provides the Powertrain Control Module (PCM) with an input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance (output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from .26 volts at minimum throttle opening (idle), to 4.49 volts at wide-open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations:
Ignition timing advance Fuel injection pulse-width Idle (learned value or minimum TPS) Off-idle (0.06 volt) Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage) Deceleration fuel lean out Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage) A/C WOT cutoff (certain automatic transmissions only)
