It is on the side of the throttle body opposite the throttle cable.
It is located on the throttle body, opposite side of where the throttle cable is attached.
The throttle position sensor is on the throttle body.
According to my factory service manual the voltage at the throttle position sensor should vary from about 0.5 volts in the idle position to 5.0 volts in the wide open throttle position.
On a 1987 Chevy Celebrity with a 2.8L multi-port fuel injection engine, the throttle position sensor (TPS) is located on the throttle body, which is mounted on the intake manifold. It is typically positioned on the side of the throttle body and can be identified by its electrical connector and a small lever that connects to the throttle plate. To access it, you may need to remove any air intake components or ducting that obstructs the view.
The idle speed is read by the Engine Control Module(computer) and adjusted as necessary by use of the idle air control in conjunction with the throttle position sensor. There is no separate idle sensor as such.
To install the throttle position sensor (TPS) on a 1987 Pontiac Fiero, first disconnect the negative battery terminal to ensure safety. Remove the electrical connector from the old TPS, then unscrew the sensor from the throttle body. Position the new TPS in place, aligning it properly, and secure it with screws. Finally, reconnect the electrical connector and the battery terminal, then check for proper operation.
its either a vacume pipe leak or in my case a bad throttle position sensor
The MAP sensor on a 1987 Chevy Celebrity is mounted to the firewall near the right fender.
To adjust the throttle position sensor (TPS) on a 1987 Buick Century with a 3.8-liter engine, first, locate the TPS mounted on the throttle body. Use a multimeter to check the voltage output of the sensor, which should be between 0.5 to 0.6 volts at closed throttle. Loosen the screws securing the TPS, and rotate it slightly until the voltage reading is within the specified range. Once adjusted, tighten the screws securely and recheck the voltage to ensure it remains within the desired range.
It is on the air intake housing straight across from where the accelerator cable hooks up.
Possibly the throttle position sensor has failed.
