P1101 on Cadillac
On GM and GM-era Saab engines, the airflow worked out from throttle position doesn't match the airflow measured by the MAF and MAP sensors
Severity: Inspect soon
An air leak or sensor error upsets fuelling and, on some GM turbo engines, triggers a Reduced Engine Power message. It usually isn't an emergency, but a steady check engine light should be inspected promptly.
