The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P258D will range between $75 and $150, depending on the repair time required. These factors should be considered when estimating the cost of fixing the P258D fault code.

The P258D code is related to the Vacuum Pump Control Circuit signal. The Powertrain Control Module (PCM) keeps an eye on this signal. If the signal is not within factory specifications, the PCM sets the OBDII code.

The P258D code specifically indicates that the Vacuum Pump Control Circuit signal is high.

What are the possible causes of the P258D automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P258D fault code. This code is caused by a faulty vacuum pump control, an open or shorted vacuum pump control harness, or a poor electrical connection in the vacuum pump control 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 one visually inspect the related wiring harness and connectors to fix the P258D fault code?

If you’re experiencing the P258D fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Vacuum Pump Control, an open or shorted Vacuum Pump Control harness, or a poor electrical connection in the Vacuum Pump Control circuit.
