U0703 OBD-II Diagnostic Network (U) Trouble Code DescriptionU0703 engine trouble code is about Exhaust Gas Recirculation Sensor B Circuit High.
Main reason For U0703 CodeThe reason of U0703 OBD-II Engine Trouble Code is Fuel Rail Pressure Sensor Circuit Malfunction.
U0703 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
