In this hybrid vehicle tech tip Dave Hobbs talks about an ‘engine stop request code. If you’ve got a hybrid vehicle and you’re not sure– is it doing an idle stop or is it just stalling– because we have still have an internal combustion engine and that means we still have all other kinds of sensors that can cause drivability issues, including intermittent stalling conditions. Thats why Dave talks about the engine stop request PID and how it can keep you from chasing the boogeyman.
