Check harness continuity between ECM terminal 52 and turbocharger boost sensor terminal 2. Refer to 2. Also check harness for short to ground and short to power. OK or NG OK >> GO TO 5. NG >> Repair open circuit or short to ground or short to power in harness connectors. 5. CHECK TURBOCHARGER BOOST SENSOR Refer to EC-181, "Component Inspection" . OK or NG OK >> GO TO 6. NG >> Replace turbocharger boost sensor. 6. CHECK INTERMITTENT INCIDENT Refer to EC-75, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" . >> INSPECTION END Component Inspection EBS013NO CHECK TURBOCHARGER BOOST SENSOR 1. Remove turbocharger boost sensor with its harness connected. 2. Turn ignition switch ON. 3. Use pump to apply pressure sensor as shown in the figure. CAUTION: ● Always calibrate the pressure pump gauge when using it. ● Inspection should be done at room temperature [10-30 ° C (50-86 ° F)]. 4. Check the output voltage between turbocharger boost sensor terminal 2 and body ground. Removal and Installation EBS013NP TURBOCHARGER BOOST SENSOR Refer to Continuity should exist.
