Test TC: Step 30

30) Code 26: Check Transmission Oil Operating Temperature  Code 26 indicates Transmission Oil Temperature (TOT) sensor is out of Self-Test range. Correct voltage is 0.21-3.50. Possible causes for this fault are: TOT resistance is out of range or ECA is faulty. Drive vehicle normally in city traffic for 20-30 minutes to bring transmission oil temperature to at least 50° F (10°C). In extremely cold weather a longer warm-up drive may be necessary. Rerun QUICK TEST. If code 26 is still present, go to next step. If code 26 is no longer present, service or repair other codes as necessary.
