P2588

DTC P2588, sometimes indicated as P258800 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the engine idling stability causing turbocharger boost control position sensor "b" circuit low.

This code is set when the PCM detects a low voltage (compared to normal) in the boost control position sensor circuit. This sensor is used by the PCM to determine the position of the turbocharger's wastegate.
Possible causes of this code include a defective boost control position sensor, a short or open in the wiring or connector to the sensor, or a defective PCM.
If this code is caused by a defective boost control position sensor, the sensor will need to be replaced. If the code is caused by a short or open in the wiring or connector to the sensor, the wiring or connector will need to be repaired or replaced. If the code is caused by a defective PCM, the PCM will need to be replaced.
