Answer 1

Hi there,

These codes are related to the engine speed. If there isn't any code for the crank position sensor, then the issue is either on the signal line from the tcm to the ecm, or the ecm itself is at fault. The code is there because the ecm is not seeing the engine speed in the transmission control module.
