P0845 TRANSMISSION FLUID PRESSURE SEN/SW B TM-79 < DTC/CIRCUIT DIAGNOSIS > [CVT: RE0F09B] C E F G H I J K L M A B TM N O P P0845 TRANSMISSION FLUID PRESSURE SEN/SW B Description INFOID:0000000005514026 The primary pressure sensor detects primary pressure of CVT and sends a signal to the TCM. DTC Logic INFOID:0000000005514027 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE NOTE: 1. CHECK DTC DETECTION With CONSULT-III 1. Turn ignition switch ON. 2. Select “Data Monitor” in “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” detected? YES >> Go to NO >> Check intermittent incident. Refer to GI-39, "Intermittent Incident" . Diagnosis Procedure INFOID:0000000005514028 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. Is the inspection result normal? DTC Trouble diagnosis name DTC is detected if...
