I've heard more than once that carb cleaner will damage an 02 sensor as well. It may be a myth. I've never bothered to find out since I hardly ever work on anything with an 02 sensor anymore.
Yup if you use it liberally on the intake it'll throw them out of whack as well since it's exposed element kinda like a MAF sensor, but obviously the MAF is quite a bit more sensative. Spraying a
little on the inside of the throttle body (on the blade, not on the outside where the TPS is) and wiping it down without the engine running isn't going to do anything, but blindly spraying a bunch of it into the throttle body while the engine is running definitely can screw up the O2 sensors.
Despite what a couple of others here think, there's a reason why it's
Carb and
choke cleaner lol. Ideally on fuel injected cars you want to use MAF cleaner for the MAF, and TB/Intake cleaner for the throttle body - go figure. You can use the MAF cleaner on the TB as well without killing any sensors, but it's not that strong of a solvent for obvious reasons. Depending on the vehicle, the PCV line can crud up the TB on some cars (they dump the return line before the MAF and it gets the oil mist), and definitely will in the intake, so MAF cleaner usually doesn't help much there and can actually make it worse since it just allows the deposits to pool up but not get rid of them. That's why they always "recommend" on the can that you remove the MAF when cleaning it as well. Carbureted cars/bikes are way easier in this aspect since you don't have all the electronic sensors to worry about and can just the stronger solvent right from the start. Fuel injected stuff you always got to juggle having a powerful enough solvent to clean a given area, but not kill any sensor's downstream of what you're cleaning.
Sorry to go on another tirade lol, and it's not directed towards you SooperDave, but I've seen a lot of cars with issues that grew from something simple and someone thought they could fix by spraying the first cleaner they could find where ever they think looks good. Then after they make it worse they'll have someone else look at it and now instead of just properly cleaning the MAF, you got to replace an expensive O2 or TPS sensor.
On the flip side of that for me, I hate electricity and electricity hates me lol. So I learned that whenever I have an issue with home electrical stuff I call up a buddy that deals with it first thing and don't touch it at all as I'll most likely just make things worse/fry something (myself included).
