Walker 200-1185 throttle position sensor for the 1989 Geo Spectrum 4-cylinder 1.5L and other vehicles reads throttle blade position and sends it to the engine computer. The computer uses that voltage signal with other inputs to work out how much fuel to deliver.
Poor acceleration, a rough idle, stalling or a throttle-related trouble code can mean this sensor is worn, though a damaged wiring connector or a dirty throttle body can produce similar symptoms.
This direct-fit replacement suits the 1989 Geo Spectrum 4-cylinder 1.5L, the 1986-1988 Chevrolet Spectrum 4-cylinder 1.5L and the 1987-1988 Isuzu I-Mark 4-cylinder 1.5L. The listing is one sensor, which is all these cars need.
Fit and size
Build and materials

Yes. Walker 200-1185 is a direct-fit replacement for the 1989 Geo Spectrum 4-cylinder 1.5L, and that car takes one sensor.
Is the Walker throttle position sensor adjustable?
Yes. This Walker 200-1185 sensor is listed as adjustable and is throttle body mounted.
Do the mounting bracket and hardware come with this throttle position sensor?
No. This listing is the sensor alone. The mounting bracket and mounting hardware are not included.
How many terminals are in the connector on this throttle position sensor?
