ETC MOTOR

NOTE: Take the following measurement using special tool #8815
to avoid possible damage to the Throttle Body harness connec-
tor.
Measure the resistance of the ETC Motor between the (K447) ETC
Positive circuit and the (K448) ETC Negative circuit at the appropriate
terminals of special tool #8815.

Is the resistance between 2.5 and 25 ohms at closed throttle?

Yes

>> Go To 11

No

>> Replace the Throttle Body Assembly. Disconnect the Bat-

tery when replacing the Throttle Body Assembly. After
installation is complete, use a scan tool and select the
ETC RELEARN function.

Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)

PCM

NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal
push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and
Ground circuits.

Were there any problems found?

Yes

>> Repair as necessary.

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
