Measure the sensor output voltage at ECU check harness special tool MB992044 between the (2) Turn the ignition switch to the "ON" position. (3) Measure the voltage between terminal No. 41 of ENGINE-ECU check harness and ground. • When altitude is 0 m, voltage should be 4.01 to 4.15 volts. • When altitude is 600 m, voltage should be 3.76 to 3.92 volts. • When altitude is 1,200 m, voltage should be 3.45 to 3.62 volts. • When altitude is 1,800 m, voltage should be 3.2 to 3.3 volts. (4) Turn the ignition switch to the "LOCK" (OFF) position. Q: Is the measured voltage correct? YES : It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use − How to Cope with Intermittent Malfunctions . NO : Replace the sensor. Then go to Step 12. STEP 12. Test the EOBD drive cycle. Diagnostic Function − EOBD Drive Cycle − . (2) Check the diagnostic trouble code (DTC). Q: Is DTC P0107 set? YES : Retry the troubleshooting. 16DB400A COVER ENGINE CONTROL UNIT AIR CLEANER 03DB224A B-20 HARNESS CONNECTOR |
