The fault code P256E indicates a problem with the turbocharger boost control position sensor circuit. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P256E code is an OBDII fault code that indicates an issue with the Engine Idle Speed Selector SensorSwitch circuit signal. The Engine Control Module (ECM) monitors this signal and sets the code when it is out of factory specifications. This fault code specifically refers to an intermittent or erratic signal from the Engine Idle Speed Selector SensorSwitch circuit.

This means that the signal is not consistently within the expected range, which can cause issues with engine performance and efficiency. If you receive a P256E code, it is important to have your vehicle diagnosed and repaired by a qualified mechanic. Ignoring this issue can lead to further damage to your engine and potentially more expensive repairs down the line.

What are the possible causes of the automobile fault code P256E?

If you see the engine light on or service engine soon warning light, it could be due to the P256E fault code. This code is usually caused by a faulty engine idle speed selector sensor/switch, an open or shorted harness, or a poor electrical connection in the sensor/switch circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P256E fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P256E fault code, you may need to visually inspect the related wiring harness and connectors. This fault code is caused by a faulty Engine Idle Speed Selector Sensor/Switch, an open or shorted harness, or a poor electrical connection. To fix the issue, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
