Main code 33 indicates the sump temperature sensor is providing a signal outside the usable range of the ECU. Main code 33 can be caused by a component or circuit failure or by extremely high temperatures.

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.
