6-12 EXHAUST SYSTEM • Turn the ignition switch ON. • Measure the position sensor output voltage at fully close posi- V tion. Position sensor output voltage EXCV is fully close: 0.5 output voltage 1.3 V (+ Yellow – - B/Br) 09900-25008: Multi circuit tester set 09900-25009: Needle pointed probe set Tester knob indication: Voltage () If the measured voltage is less than specification, adjust the No.1 cable adjuster as follows: • Set the EXCVA to adjustment position. (6-4)  Adjusting the No. 1 cable with the EXCV fully closed can damage the EXCVA. Be sure to adjust the No.1 cable with the EXCV set in adjustment position. • Turn out the No. 1 cable adjuster 3. • Repeat the above procedure until the output voltage becomes E specified value. L Position sensor output voltage EXCV is fully close: 0.5 output voltage 1.3 V P • To next step. M NOTE: If C46 code is indicated after adjusting the voltage, increase the voltage to 0.9 V. SA 4th step: To set the EXCV to fully open position, apply 12 volts to A and B terminals. Positive wire –– B (Gray wire) terminal Negative wire –– A (Pink wire) terminal  12 V To prevent the motor damage, stop applying 12 V as soon as the EXCV reaches fully open position. Measure the position sensor output voltage at fully open posi- tion. V Position sensor output voltage EXCV is fully open: 3.7 output voltage 4.5 V (+ Yellow – - B/Br)
