P2431 Engine Trouble Code
Meaning of P2431 engine trouble code is a kind of powertrain trouble code and P2431 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 $2,140 and you can't do it yourself unless you're an experienced mechanic.

P2431 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.
P2431 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Fuel And Air Metering (Injector Circuit Malfunctions Only)||O2 Sensor Heater Circuit Malfunction||Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)||Crankshaft Position Sensor A Circuit Low Input|
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.
P2431 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP2431 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.
Main reason For P2431 CodeThe reason of P2431 OBD-II Engine Trouble Code is O2 Sensor Heater Circuit Malfunction.
P2431 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.
