This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
C1873 Code Meaning :
|OBD-II Diagnostic Chassis (C) Trouble Code For Engine||Fuel And Air Metering||Engine Oil Temperature Sensor Malfunction||Cylinder 10 Contribution/balance Fault||Exhaust Gas Recirculation Sensor B Circuit High|
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
C1873 OBD-II Diagnostic Chassis (C) Trouble Code DescriptionC1873 engine trouble code is about Exhaust Gas Recirculation Sensor B Circuit High.
Reason For C1873 CodeThe reason of C1873 OBD-II Engine Trouble Code is Engine Oil Temperature Sensor Malfunction.
C1873 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.
