    Temp. (°C) Temp. (°F) Resistance (kΩ) Temp. (°C) Temp. (°F) Resistance (kΩ)
    -20 -4 16.52 40 104 1.11
    0 32 6 60 140 0.54
    20 68 2.45 80 176 0.29
  3. Is the measured resistance within specification?

    YES 

    • Clear DTC and Test-drive under the Prerequisite Condition. After the road test, if this DTC is set, recheck resistance. If not, it is intermittent fault. Go to "Verification Of Repair ".

    NO 

    • Check OTS for contamination, deterioration, or damage. Substitute with a known-good OTS and check for proper operation. If the problem is corrected, replace OTS and then Go to "Verification Of Repair " procedure.
