Throttle Position (TP) Sensor -G69-, Installing New-Style Switch
24 07 01 Jan. 10, 2007, 2004112, supersedes Technical Bulletin Group 24 number 03-02, Feb. 3, 2003 due to inclusion in ElsaWeb.
The "old style" Throttle Position (TP) sensor -G69- has separate connector housings to the Transmission Control Module (TCM) -J217- harness.
In the "new style" TP sensor, see Required Parts and Tools, the Engine Control Module (ECM) -J220- harness is replaced by an ECM connector
If the TP sensor is replaced with a new sensor, see Required Parts and Tools (arrow), it requires a wiring harness modification, which:
splices signal wire (terminal 2) of wire harness from TCM connector at TP sensor into signal wire (terminal 2) of wire harness from ECM
connector at TP sensor, and
terminates unused wiring from TCM connector (terminal 1 - power) and terminal 3 - ground.
Install new TP sensor -G69- using two M4 x 12 Phillips-head screws, see Required Parts and Tools.See also Repair Group 24 Throttle Position
(TP) Sensor, replacing.
Remove terminal from Position 2 in (three-wire) TP sensor connector on throttle body.
Locate repair wire (with replacement terminal that matches terminal from TP sensor connector) in the Wiring Harness Repair Kit.See Required
Parts and Tools.
Install repair wire into Position 2 of the (three-wire) TP sensor connector and install appropriate seal (over wire) into connector housing.
Cut repair wire approximately 75 mm from connector.
Strip insulation and install (crimp) a red splice connector, see Required Parts and Tools, to the repair wire, using an appropriate crimping tool
from the Wiring Harness Repair Kit.
Remove tape as necessary from ECM and TCM wire harnesses leading to TP sensor.
Remove terminal and strip insulation from ECM signal wire (Position 2 of 3-wire connector housing).
Remove terminal and strip insulation from TCM signal wire (Position 2 of 4-wire connector housing).
