Fuel-Cut (Slow-Cut) System (2.6L)
- Warm engine to operating temperature. Turn ignition off. Unplug throttle valve switch wire connector.NOTE: Throttle valve switch and throttle position sensor are mounted on throttle body throttle shaft. M/T models use throttle valve switch. A/T models use throttle position sensor and throttle valve switch.
- Insert a fine wire into upper (idle) terminal. Reconnect throttle valve switch connector with fine wire partially pulled outward. See Fig 1 .
- Start engine, and operate at 2000-2500 RPM. Connect battery voltage to fine wire installed on throttle valve switch. When battery voltage is applied, engine speed should decrease to approximately 1250 RPM. Engine surging may occur, which is normal during test procedure.
NOTE:
Fuel cut-off and fuel injection reactivation is controlled by throttle valve switch. See FUEL-CUT SPECIFICATIONS
table for fuel-cut operating conditions.
