P0790 OBD-II: normal/Performance Switch Circuit
P0790 Severity
Will P0790 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 P0790?
Code P0790 may be stored if there is a fault in the transmission. Other codes are usually stored with P0790 and should be diagnosed and repaired first.
