TM-80 < COMPONENT DIAGNOSIS > [CVT: RE0F09B] P0845 TRANSMISSION FLUID PRESSURE SENSOR B (PRI PRESSURE SEN- SOR) P0845 TRANSMISSION FLUID PRESSURE SENSOR B (PRI PRESSURE Description INFOID:0000000003849010 The transmission fluid pressure sensor B (primary pressure sensor) detects primary pressure of CVT and DTC Logic INFOID:0000000003849011 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE NOTE: 1. CHECK DTC DETECTION With CONSULT-III 1. Turn ignition switch ON. 2. Select “Data Monitor” mode for “TRANSMISSION”. 3. Make sure that output voltage of line temperature sensor is within the range below. 4. Start engine and wait for at least 5 consecutive seconds. With GST Follow the procedure “With CONSULT-III”. Is “P0845 TR PRS SENS/B CIRC” detected? YES >> Go to NO >> Check intermittent incident. Refer to GI-35, "Intermittent Incident" . Diagnosis Procedure INFOID:0000000003849012 1. CHECK INPUT SIGNAL 1. Start engine. 2. Check voltage between TCM connector terminal and ground. Is the inspection result normal? YES >> GO TO 8. NO >> GO TO 2. 2. CHECK SENSOR POWER AND SENSOR GROUND Check voltage between TCM connector terminals. DTC Item (CONSULT-III screen term) Malfunction is detected when...
