P0256 Diagnostic Trouble Code Meaning And Solution

P 0 2 56
Powertrain Problem SAE - Generic Fuel And Air Metering (Injector Circuit Malfunctions Only) 56 Engine Fault Code

Starting letter P diagnostic code shows that there are problems in engine, transmission and emissions systems.
If your "Check Engine Light" is on, it means your vehicle has one or more OBD II Trouble Codes so you have to check your engine diagnostic code tool. If your vehicle is an older model with a non-electronic Fuel And Air Metering (Injector Circuit Malfunctions Only), you can check the distributor cap to see whether the spark is getting from there to the coil and on to the spark plugs.

Don't forget ! If your P0256 engine code not resolved on and there are trouble codes in your computer, your vehicle will not pass an OBD 2 emissions test. The light must be off and there must be no codes in memory to pass an OBD 2 emissions test. In addition, all of the OBD II self-monitors that check for faults must have run and completed without finding any further problems to pass the test.
