U229A Mercedes Sl 400 OBD Code

OBD/2 U229A error code description and symptoms.

The input turbine speed sensor detects rotation of the input shaft of the input shaft speed sensor transmission. The computer uses that information, along with the output shaft speed sensor to determine if the transmission is operating according to plan. If the computer detects a difference between the input shaft speed , and the expected output shaft speed, it will adjust transmission pump pressure to prevent clutch disc slip. If adding pressure doesn't solve the problem, it will set a trouble code.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U229A, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U229A on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
