P2071 Engine Trouble Code

Meaning of P2071 engine trouble code is a kind of powertrain 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 $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

P2071 Fault Symptoms :

  1. Check engine light comes on
  2. Engine stalling or misfiring
  3. Engine performance issues
  4. Car not starting
If one of these reasons for P2071 code is occuring now you should check P2071 repair processes.
Now don't ask yourself; What should you do with P2071 code ?
The solution is here :

P2071 Possible Solution:

P2071 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.

P2071 Code Meaning :

P 2 0 7 1
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Fuel And Air Metering (Injector Circuit Malfunctions Only) Ambient Air Temperature Sensor Circuit Low Cylinder 10 Contribution/balance Fault 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.

P2071 OBD-II Diagnostic Powertrain (P) Trouble Code Description

P2071 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.

Main reason For P2071 Code

The reason of P2071 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.

P2071 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.
