Main code 33 indicates the sump temperature sensor is providing a signal outside the usable range of the ECU. This code indicates the sensor failed showing abnormally low temperature readings.
Main code 33 Causes:
1. Component or circuit failure
2. Extremely high or low temperatures.
There are no operational inhibits related to main code 33. The ECU assumes a hardware failure and that transmission temperatures are normal (93oC; 200oF). Temperatures above or below normal cause poor shift quality.
