The P1191 fault code refers to a problem with the Electronic Throttle System (ETS) Limp Home Valve. This valve is located under the throttle body and allows air to flow from the outside to the engine combustion chamber.

Its purpose is to prevent the engine from stalling when the Powertrain Control Module (PCM) detects a malfunction in the ETS system. When this fault code is triggered, it indicates that there is an issue with the ETS Limp Home Valve.

This could be due to a variety of reasons, such as a faulty valve or a problem with the wiring or connectors.

It is important to address this issue promptly to ensure the proper functioning of the throttle system and prevent potential engine stall situations.
