<<See All OBD Codes

Terrorized? Can’t decide on what to do next? How to diagnose the error code P256C? Well, Parts Avatar has you covered! We have listed here all that you need to know about the error code P256C. This OBD-II code engine may stall is determined as an engine idle speed selector sensor/switch circuit low. The engine’s idle speed is controlled and managed by the idle control valve (idle speed selector overseas). At times, when the idle speed cannot be properly regulated as required by the engine computer, it will cause code P256C to be stored.

One can observe that the engine idle speed selector sensor/switch circuit signal is constantly monitored by the engine control module (ECM). Then engine control module (ECM) registers the code P256C as soon as the engine idle speed selector sensor/switch signal fails to fall within the desired manufacturer’ specifications.

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

• A jammed or defective engine idle speed selector sensor/switch
• Loose or short circuited engine idle speed selector sensor/switch harness
• A weak electrical connection present in the engine idle speed selector sensor/switch circuit

1. Engine Control Module - Are you facing problems caused due to the error code P256C? An inferior quality engine control module can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P256C. It triggers problems like an inability to shift up and a decreased fuel economy. Tune into Parts Avatar for supreme quality engine control module available at economical prices.
2. Speed Selector Sensor - Now get your error code P256C solved immediately by simply fixing your speed selector sensor. Also, a faulty one is likely to stimulate problems like failed operations in a cruise system and harsh or improper shifting. We advise you to get your speed selector sensor changed as soon as possible.
3. Powertrain Control Module - Well, a number of unexplained symptoms are likely to be experienced as soon as the powertrain control module gets damaged. The powertrain control module enables the system and transmission to work in tandem. So a faulty PCM can affect not only a few parts but the functioning of the entire system. Tune into Parts Avatar for top notch sets of PCM.

We have stocked a wide range of best priced ECM, speed selector sensor, PCM, idle air control valve, transmission parts, IAC valve, neutral safety switch, oil pressure switch, shift solenoid, oil drain plug, speedometer gauge, connecting rod bearing, clutch pressure plate and a lot more to help you out in fixing your car.

A scanner (or code reader) and a digital volt/ohmmeter will be helpful in successfully diagnosing this code-storing condition.Begin your diagnosis with a visual inspection of system wiring, connectors, and components.Repair or replace 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.This information can be extremely helpful in diagnosing intermittent conditions that may have contributed to this code being stored. After the codes are cleared, operate the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.
