P1000 Severity
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.
In order to meet EPA emissions standards, the engine computer (PCM) must complete multiple self-checks known as readiness monitors. If the PCM has not yet been able to complete all the monitors since the last time any codes were cleared, any repairs were made, or the battery was disconnected, code P1000 may set. in order for this code to clear, the vehicle must be driven until all monitors are completed.
