What is U111300 function limitation due to received malfunction value?
Fault code u111300 indicates a communication error between control modules, often due to wiring issues or can bus interruptions. Repairing the p0113 error involves addressing the root cause of the high input signal detected by the engine control module. This process may include: replacing a faulty iat sensor. Repairing or replacing damaged wiring or connectors in the iat sensor circuit.A vacuum leak downstream of the IAT sensor could potentially cause a P0113 by allowing warmer underhood air to enter the intake and heat up the sensor prematurely. However, vacuum leaks more commonly trigger lean mixture codes like P0171 and P0174.There are several causes for the triggering of error code P0113. You may experience an issue with your IAT or MAF sensors, or they may cease working altogether. These sensors may need to be cleaned and adjusted. A dirty air filter can also cause said code to appear.
What is the purpose of U111300?
Fault code U111300 indicates a communication error between control modules, often due to wiring issues or CAN bus interruptions. Since no dashboard lights remain on and the car drives normally, it’s likely a transient fault. Check wiring harnesses for damage or loose connectors near the instrument cluster and ECU. The U112300 error indicates a communication fault between the AC control module and other vehicle systems. Start by checking the AC control unit’s wiring harness for loose or corroded connectors. Inspect the CAN bus lines for damage or shorts. Resetting the error codes with a diagnostic tool can help.
