C2031 Engine Trouble Code

Meaning of C2031 engine trouble code is a kind of chassis trouble code and theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $240-$400 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

C2031 Possible Solution:

C2031 Engine

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.

C2031 Code Meaning :

C 2 0 3 1
OBD-II Diagnostic Chassis (C) Trouble Code For Engine Fuel And Air Metering (Injector Circuit Malfunctions Only) Ambient Air Temperature Sensor Circuit Low Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector) Crankshaft Position Sensor A Circuit Low Input

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

C2031 OBD-II Diagnostic Chassis (C) Trouble Code Description

C2031 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.

Main reason For C2031 Code

The reason of C2031 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.

C2031 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.
