When you apply the caveat I wrote about poorly tuned it is,........I can't see in the this case how there would be over 25000 PPM CO to set the sensor off at the LEL in the engine compartment without some seriously obvious disaster, which according to him he does not have.

FWIW.....The above is just my opinion.

Re: engine alarm
Well, I can tell you my personal experience is that on two different occasions I've had exhaust leaks over the years on an engine that would certainly not be considered "poorly tuned" and it did set off the combustible gas sensor from the exhaust gases. There is always a small bit of unburnt gasoline in the exhaust (unless you have a catalyst to burn that off) and there is also a substantial amount of Carbon Monoxide. Between the two, it's very easy to get over 10% of the LEL.

Re: engine alarm
That is pretty much what I said.....not sure why we are arguing about the same thing...it is about 20% lel, but with each makers unit the spec may just be a bit different, but there may be a reg here...... As with any gas testing there are circumstances specific to each case that alter the way the case is handled.
Let's get back to the issue here when he finds out for sure what alarm he has got going.
