Laser FWD L4-1997cc 2.0L DOHC Turbo (1993)
1. Disconnect the throttle position sensor connector.
2. Measure resistance between terminal (4) (sensor ground) and terminal (1) (sensor power).
Standard value: 3.5k - 6.5k Ohms
3. Connect a pointer type ohmmeter between terminal (4) (sensor ground) and terminal (2) (sensor output).
4. Operate the throttle valve slowly from the idle position to the full open position and check that the resistance changes smoothly in proportion with
the throttle valve opening angle.
5. If the resistance is out of specification, or fails to change smoothly. replace the throttle position sensor.
Throttle position sensor installation torque:
1.5-2.5 Nm (1.1 -1.8 ft lb)
