1. Disconnect throttle position sensor connector.
2. On automatic transmissions, proceed as follows:
a. Measure resistance between terminals 12 and 21, Fig. 16.
b. With throttle valve closed fully resistance should be 29 ohms or less.
c. With throttle valve opened fully resistance should be 1M ohms or more.
d. Measure resistance between terminals 32 and 21.
e. With throttle valve closed fully resistance should be 29 ohms or less.
f. With throttle valve opened fully resistance should be 1M ohms or more.
3. On manual transmissions, proceed as follows:
a. Measure resistance between terminals 12 and 29, Fig. 17.
b. With throttle valve closed fully resistance should be 29 ohms or less at 68°F.
c. With throttle valve opened fully resistance should be 1M ohms or more.
d. Measure resistance between terminals 32 and 29.
e. With throttle valve closed fully resistance should be 1M ohms or more.
f. With throttle valve opened fully resistance should be 29 ohms or less.
4. On all models, replace throttle position sensor if specifications are not met.
5. Perform TPS circuit test.
