P255F OBD-II: A/C Request "A" Circuit Range/Performance

P255F Severity

Moderate

Will P255F go away on its own?

Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.

For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.

Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.

What causes OBD-II fault code P255F?

When the driver requests the A/C to be turned on, a signal goes from the switch to the engine computer (PCM). The PCM then sends power to the A/C Compressor to turn it on. If the Compressor fails to turn on, code P255F will be stored.
