Schematic of the Transmission Intermediate Speed SensorThis diagnostic code is recorded when the ECM receives an incorrect output signal from the transmission Intermediate speed sensor. The signal is below the dropout signal level. The engine must be running in order to initially log the diagnostic code for the sensor. The incorrect signal that is being read by the ECM has the following characteristics:
Erratic
Intermittent
IncorrectThe ECM determines that this condition exists by comparing the information from the signals. The ECM compares the two signals from the speed sensors. The ECM checks if one of the two signals is invalid or out of the range.The following conditions must be present before the diagnostic code will be active:
The signal from the transmission intermediate speed sensor to the ECM is incorrect.Note: The ECM will not see a signal from the speed sensor unless the engine is running. When the ECM determines that a signal exists, the diagnostic code is not active.Test Step 1. CHECK THE SENSOR RESISTANCE.
Turn the disconnect switch to the OFF position.
