P1719

Diagnostic Chart:

The transmission control module (TCM) uses the transaxle input speed sensor (ISS) and output speed sensor (OSS) to determine input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio. The TCM measures the amount of time between the moment that a gear shift is commanded and the moment that a gear shift has taken place. DTC P1719 sets if shift times are too long or too short, indicating a malfunction.

DTC PARAMETERS
DTC P1719 will set if the TCM detects shift time too long or too short, or engine flare when shifting and:
^ A forward gear is selected
^ Transaxle Fluid Temperature is at least 60°C (140°F)
^ The condition exists 5 times

The TCM will command Transaxle Protection Mode ON if this DTC is active.

DTC P1719 is a type A DTC.

DIAGNOSTIC AIDS

IMPORTANT: If any other DTC is set, diagnose that DTC first.

Possible causes of incorrect shining:
^ Low transaxle fluid level
^ Incorrect transaxle fluid type
^ Contaminated transaxle fluid
^ Poor electrical connections
^ Inaccurate TFT sensor
^ Inaccurate speed sensors
^ Valvebody
^ Mechanical failure
