INSTALLATION - 3.9L/5.2L/5.9L
The throttle shaft end of the throttle body slides
into a socket in the TPS (Fig. 63). The TPS must be
installed so that it can be rotated a few degrees. If
the sensor will not rotate, install the sensor with the
throttle shaft on the other side of the socket tangs.
The TPS will be under slight tension when rotated.
