Mitsubishi Eclipse / Eclipse Spyder (2000-2002). Service and repair manual — part 198

THROTTLE BODY ASSEMBLY

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-491

2. Check if the vacuum port or passage is clogged. Use

compressed air to clean the vacuum passage.

ASSEMBLY SERVICE POINTS

>>A<< THROTTLE POSITION SENSOR (TPS)
INSTALLATION
1. Install the throttle position sensor to the throttle body as

shown in the illustration.

2. Turn the throttle position sensor 90 degrees

counterclockwise to set it, and tighten the screws.

3. Connect an ohmmeter between terminals 1 (ground) and 3

(output), or between terminals 3 (output) and 4 (power).
Then, make sure that the resistance changes smoothly
when the throttle valve is slowly moved to the fully open
position.
