How to Check 2010 1.6 DOHC Hyundai Elantra

P0712 Transaxle Fluid Temperature Sensor Circuit Low Circuit

Study Guide Component Inspection Check "TRANSAXLE FLUID TEMPERATURE SENSOR" 1. Study Ignition "OFF" . 2. Study Disconnect the "TRANSAXLE FLUID TEMPERATURE SENSOR" connector 3. Study Measure the resistance between terminals "5" and "6" of the "TRANSAXLE FLUID TEMPERATURE SENSOR". A. Study the Specification : Refer to " Reference data" TEMP.(°C) RESISTANCE(kΩ) TEMP.(°C) RESISTANCE(kΩ) -40(-40°F) 139.5 80(176°F) 1.08 -20(-4°F) 47.7 100(212°F) 0.63 0(32°F) 18.6 120(248°F) 0.38 20(68°F) 8.1 140(284°F) 0.25 40(104°F) 3.8 160(320°F) 0.16 60(140°F) 1.98 Study , Study , Study , Study , Study , Study , Study , Study , Study 4. Study Is resistance within specifications or w/in Study? YES 1) Go to "CHECK PCM/TCM " as below NO 1) Study Guide Replace "TRANSAXLE FLUID TEMPERATURE SENSOR" as necessary and Go to "Verification Vehicle Repair"Study procedure. Study Guide , Study Guide , Study Guide , Study Guide , Study Guide Check TCM 1. Study Ignition "ON" & Engine "OFF". 2. Study Connect "TRANSAXLE FLUID TEMPERATURE SENSOR" connector. 3. Study Install scantool and slect a SIMU-SCAN, 4. Study Simulate voltage (0→5V) to "TRANSMISSION FLUID TEMPERATURE SENSOR" signal circuit. 5. Study Is FLUID TEMP. SENSOR signal value changed according to simulation voltage? YES 1) Study Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure. NO 1) Study Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM as necessary and go to "Verification of Vehicle Repair" procedure.

Transmission  Automatic Transaxle  P0717 A/T Input speed Sensor Circuit Low Input

Study Guide and Component Location Study Guide and General Description The Study Guide input(turbine) speed sensor outputs waveform signals according to the revolutions of the input shaft ,installed in front of End clutch retainer,of the transmission. The Study Guide TCM determines the input shaft speed by calculating the frequency of the pulses. This Study Guide value is mainly used to control the optimum fluid pressure during shifting. Study Guide and DTC Description The Study Guide PCM/TCM sets this code if an output pulse-signal is not detected, from the input speed sensor, when the vehicle is running faster than 30 km/h. The Study Guide Fail-Safe function will be set by the PCM/TCM if this code is detected. DTC Detecting Condition Item Study Guide Detecting Condition Study Guide Possible Cause Study Guide Study Guide and DTC Strategy ● Speed rationality check ● Signal circuit is open or short. ● Sensor power circuit is open ● Sensor ground circuit is open ● Faulty INPUT SPEED SENSOR ● Faulty PCM/TCM Study Guide Enable Conditions ● Battery Voltage ≥ 10V ● Output speed ≥ 1000rpm ● Engine speed(Only current gear is the 1st gear) ≥ 3000rpm ● Lever position : D,3,2,L Study Guide and Threshold Value ● Input speed = 0 Study Guide and Diagnostic Time ● More than 1sec Fail Safe ● Locked into 3rd or 2nd gear. ● Manual shifting is possibe(2 nd → 3 rd ,3 rd → 2 nd) Study Guide and Specification Input shaft & Output shaft speed sensor ● Type : Hall sensor ● Current consumption : 22mA(MAX) ● sensor body and sensor connector have been unified as one.
