P256E OBD Error Code: Problem & Solutions

<<See All OBD Codes

Wondering on how to diagnose the OBD-II error code P256E flashing? Well, don’t you worry! Only for our customers we have got it all written here. This generic OBD-II code engine may stall is also known as an engine idle speed selector sensor/switch circuit. It should be noted that the task of regulating the engine’ idle speed is constantly performed by the idle control valve (idle speed selector overseas). Whensoever the idle speed fails to fall within the requirements stated by the engine’ computer, the error code P256E is set.

It is notable that the engine idle speed selector sensor/switch is controlled by the engine control module (ECM) present in the system. The OBD-II code P256E is stored by the engine control module (ECM) as soon as the engine idle speed selector sensor/switch signal fails to fall within the desired factory requirements.

What causes this problem with the Engine Idle Speed Selector Sensor/Switch Circuit Intermittent/Erratic?

• A possible fault in the engine idle speed selector sensor/switch
• The harness in the engine idle speed selector sensor/switch is disconnected or short circuited
• A deficient electrical connection running in the engine idle speed selector sensor/switch

1. Engine Control Module - Stressed? But don’t know the reason behind all these problems? A damaged engine control module leads to downward emissions along with other issues like a sluggish engine crank, failure in the emission system etc. We advise you to get your faulty engine control module changed now by simply logging into Parts Avatar.
2. Speed Selector Sensor - A distorted speed selector sensor accompanies along a lot of problems related to the functioning of the vehicle, failure in the cruise control system and also illuminates the check engine light. Don’t know where to look for? Log into Parts Avatar, your one stop destination for all the problems.
3. Powertrain Control Module - Abbreviated PCM; this is an integral control unit. So a defective one should be changed immediately as in addition to the error code it is likely to trigger problems like regular engine stalling and poor fuel economy. Tune into Parts Avatar for your new one.
4. Idle Air Control Valve - A lot of issues arise like a no start condition, sluggish engine cranks and constant vehicle stalls when the idle air control valve is malfunctioning. Tune into Parts Avatar for you new idle air control valve offered at just the right prices.

Common Symptoms

• Regular engine stalls may be observed
• An illuminated engine light (or service engine soon warning light)

We have listed out some ways which would help you to correct the occurrence of OBD code P256E. They are mentioned here as follows:

• Make sure you mend or restore a faulty engine idle speed selector sensor/switch as soon as possible
• Perform steps to fix a powerless electrical connection running in the engine idle speed selector sensor/switch
• All the corroded or disconnected harness in the engine idle speed selector sensor/switch should be changed or repaired immediately

Here are some steps which you should follow in order to diagnose this fault code P256E:

To begin the diagnosis, the first step of the mechanic should be using a scanner (or code reader) and a digital volt/ohmmeter as these will be helpful in successfully diagnosing this code-storing condition. Next, it is essential to your diagnose with a visual inspection of system wiring, connectors, and components. It is recommended to restore or mend any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. Also, repair or replace system circuits/connectors as required and retest the system to ensure that repairs were successful.

Common Mistakes When Diagnosing the P256E Code

Well, accurately diagnosing an error code can often be a tedious task. So only for your convenience we have listed here a few common mistakes that should be avoided while diagnosing the error code P256E:

• A failed idle air control (IAC) valve
• A malfunction in the powertrain control module (PCM)
• Wiring complications causing problems
