INSTALLATION
CAUTION: Slide rotary tangs into position over throttle shaft blade, then rotate throttle position sensor clockwise only to installed position. Failure to
install the throttle position sensor in this manner may result in excessive idle speeds.
1. Position the throttle position sensor so that the pigtail points toward the idle air control valve.
2. Secure throttle position sensor to throttle body with two retaining screws. Tighten to 1.2-1.8 Nm (11-16 lb in).
3. Install throttle body.
4. Connect electrical connector to harness.
NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control
module relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
5. Reconnect battery negative cable.
