    1998 Lincoln Town car Getting code 31 in Auto Temp Control what is the meaning of that code. no temp control either hot or cold


    031 B1251 IN-CAR TEMPERATURE SENSOR OPEN GO to Pinpoint Test B
    PINPOINT TEST B: IN-CAR TEMPERATURE SENSOR INOPERATIVE B1 CHECK SENSOR RESISTANCE
      NOTE: An open sensor will cause warm air discharge at 18°F (65° C) setting. A shorted sensor will cause cool discharge air at 29°F (85°C) setting.
    • Disconnect the A/C ambient air temperature sensor.
    • Using an ohmmeter, measure the resistance across the sensor terminals and compare the readings with the following sensor resistance table:

      Approximate Temperature Sensor Resistance Acceptance Range 10-20°C (50-68°F) 37K-58K ohms 20-30°C (68-86°F) 24K- 37K ohms 30-40°C (86-104°F) 16K-24K ohms
    Are resistance values within the specified limits?
    Yes No GO to B2 . REPLACE A/C ambient air temperature sensor and bracket. RESTORE vehicle. RETEST system. B2 CHECK ASPIRATOR INSTALLATION
    • Gain access to automatic temperature control sensor.
    • Check for proper installation of automatic temperature control sensor hose and elbow.
    Is aspirator installed properly and hose connected?
    Yes No GO to B3 . SERVICE automatic temperature control sensor hose and elbow as necessary. RESTORE vehicle. RETEST system. B3 CHECK CIRCUIT 470 (PK/BK) AT AUTOMATIC TEMPERATURE CONTROL SENSOR
    • Turn ignition switch to the RUN position.
    • Turn EATC module to NORM A/C position.
    • Disconnect automatic temperature control sensor.
    • Using a voltmeter, check Circuit 470 (PK/BK) for voltage at sensor connector.
    Is voltage 5 volts?
    Yes No GO to B5 . GO to B4 . B4 CHECK CIRCUIT 470 (PK/BK) FOR OPEN
    • Disconnect connector C227 at EATC module.
    • Using an ohmmeter, check Circuit 470 (PK/BK) between EATC module and automatic temperature control sensor for open.
    Is there 5 ohms or less?
    Yes No SERVICE Circuit 470 (PK/BK) for open. RETEST system. GO to B5 . B5 TEST CIRCUIT 470 (PK/BK) FOR SHORT
    • Using an ohmmeter connected to a good ground, connect other lead to EATC module connector Pin C227 , Circuit 470 (PK/BK).
    Is resistance less than 10,000 ohms?
    Yes No SERVICE Circuit 470 (PK/BK) for short. RESTORE vehicle. RETEST system. GO to B6 . B6 TEST CIRCUIT 790 (W/O) FOR OPEN
    • Using an ohmmeter, connect one lead to EATC module connector Pin C227 , Circuit 790 (W/O) and other lead to automatic temperature control sensor Circuit 790 (W/O).
    Is resistance 5 ohms or less?
    Yes No GO to B7 . SERVICE Circuit 790 (W/O). B7 TEST CIRCUIT 790 (W/O) FOR SHORT
    • Using an ohmmeter connected to a good ground, connect other lead to EATC module connector Pin C227 , Circuit 790 (W/O).
    Is resistance less than 10,000 ohms?
    Yes No SERVICE Circuit 790 (W/O) for short. RESTORE vehicle. RETEST system. REPLACE EATC module. RESTORE vehicle. RETEST system.

    Broiler and bake cycle don't work.


    Hi, welcome to fixya.

    Based on the information you've provided ( 240 in 120 out ) I'd say you need a new timer/ERC.

    I would definitely replace the control. Make sure you unplug the unit from the wall and ohm out the elements to confirm you don't have one open, you'd not want to go to the hassle of putting in a new control just to discover one of the elements is also toast.

    Also, when ordering a new control be sure to provide your model number and serial number to insure you get the correct control. Sometimes one can have two ranges seemingly identical, but if they have different serial numbers it is possible to have different revisions of electronic controls.

    Thanks for visiting "fixya" today, please take a moment and rate the info provided for you today.

    good luck.

    Need to know what oil to use in 10 HP 5000 tecumsah engine - goes on our generator and I lost the manual


    It depends on what temperature range the generator will be operating in. Below is a chart from Tecumseh that shows different oils for different temperature ranges. It says on their website to use a high quality brand name oil so you don't have to get actual Tecumseh oil.25b21be.jpg

    Destop Ambient Temperature Range


    three things you need to remember. 1 your power supply has a fan and as long as it works and stays clean you should be ok for normal operating there. 2. you need to have as big a case fan as you can fit into the computer and use two if possible, 3.never leave it running when you are done this will definately burn up a power supply and over heat processors.
