U2452 Mazda Demio Error Code Repair Process :

If your vehicle failed a U2452 test and the U2452 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses transfer case contact plate c encoder circuit failure a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look transfer case contact plate c encoder circuit failure: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Mazda Demio U2452 OBD2 Code

A common cause of code U2452 is the failure of Transfer Case Contact Plate C Encoder Circuit Failure, but there are several other possible causes as well, such as ;

Failures of clutch motion/travel sensors.
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Incorrect fuel pressure
Faulty oil control valve (OCV)

U2452 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.
