The OBD-II code P256B is stored immediately by the engine control module only when the engine idle speed selector sensor/switch signal fails to fall within the manufacturer’ specifications.

What causes this problem with the Engine Idle Speed Selector Sensor/Switch Range/Performance?

• A distorted engine idle speed selector
• Loose or short-circuited engine idle speed selector sensor/switch harness
• A powerless connection running in the engine idle speed selector sensor/switch circuit

Want to diagnose the error code P256B? Well, then you should follow these steps in order to diagnose this fault code:

A customary OBD-II trouble code scanner should be employed to diagnose this trouble code P256B. The scanner should be utilized to verify and view the freeze frame data and assess the code by a qualified mechanic. The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be cleared and the vehicle should be test driven to see if the code persists. Also, it should be noted that if the code disappears it could have likely been triggered due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing the P256B Code

It is essential to diagnose this fault code accurately. Here are some mistakes which a mechanic should avoid while diagnosing the problem that triggered a P256B code to be stored:

• Damaged idle air control (IAC) valve
• Fault in the powertrain control module (PCM)
• Wiring problem present within the system
