THROTTLE POSITION SENSOR ADJUSTMENT
1. Connect the scan tool to the data link connector. When not using the scan tool, proceed as follows.
1. Disconnect the connector of the throttle position sensor and connect the special tool (test harness: MB991348) in between.
2. Connect a digital voltmeter between terminal 3 (sensor output) and terminal 1 (sensor ground).
2. Turn the ignition switch to ON (but do not start the engine).
3. Check the throttle position sensor output voltage.
Standard value: 580 - 690 mV
4. If the voltage is outside the standard value, adjust by loosening the throttle position sensor mounting bolts and turning the throttle position sensor body. After adjusting, tighten the bolts securely.
5. Turn the ignition switch to OFF.
6. If a diagnostic trouble code is output while adjusting the throttle position sensor, use the scan tool to erase the diagnostic trouble code, or disconnect the battery negative cable from the battery terminal for 10 seconds or more, and then reconnect the cable and run the engine at idle speed for approx. 10 minutes.
