Have you had the system checked and the codes pulled? If so and nothing was found,you can bypass each alarm trigger one at a time. If you have the patience, do this yourself and park the car where it happens. If the alarm stopsgoing off wrong,you have found the trigger and/or circuit setting it off. Sometimes this is what it takes because the system is operating in it's parameters and will not set a code? Good Luck.

No you don't
You have front or upstrean O2 Sensors before the exhaust
converters & downstream or monitors in the converter outlets
You obviously have wires going to them
If you went under the vehicle you wouldn't be asking
