U203E Chery A3 OBD Code

OBD/2 U203E 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.

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source. Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.

If your front wiper motor relay circuit open (changed from failure 2/6/97) check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U203E and engine control unit are in charge of monitoring a bunch of different front wiper motor relay circuit open (changed from failure 2/6/97), and if they get a reading that's a little out of whack, up pops the check engine light.

Faulty Air Flow Meter
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Engine Control Module (ECM)
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection

U203E is a kind of Network Trouble Code

U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.
