  1. IG "OFF". Disconnect OTS connector.
  2. Measure the resistance between signal terminal and ground terminal of OTS connector. (Component side)

    Specification:  Approx. 5 Ω

    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 measured value within specification?

    YES 

    • Clear DTC and Test-drive under the enable conditions. After the road test, if this DTC is set, recheck resistance. If not, it is intermittent fault. Go to "VERIFICATION OF VEHICLE 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 VEHICLE REPAIR " procedure.
