P0473 Engine Trouble Code
Meaning of P0473 engine trouble code is : P0473 if your catalytic convertor fails completely, you eventually won't be able to keep the car running. Your gas mileage will also be terrible, so you should try and fix it as soon as you can. Unfortunately, the average replacement cost is around $2,000 and you can't do it yourself unless you're an experienced mechanic.
P0473 Possible Solution:
Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.
P0473 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||O2 Sensor Heater Circuit 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.
P0473 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0473 OBD-II Trouble Code The Exhaust Back Pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Engine Control Module ( P0473 code.
Reason For P0473 CodeThe reason of P0473 OBD-II Engine Trouble Code is O2 Sensor Heater Circuit Malfunction.
P0473 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
