Hah, my car does have real TPMS sensors but the dashboard display is such that the only thing it can say is a vague "low tire pressure" warning, with no indication of which tire or how low it is. I should get an OBD adapter one of these days.
- el_benhameen 4y agoSpeaking from experience, OBD will not necessarily help you here. Something has to put the TPMS data out on the CAN bus. The rudimentary system in my old Corolla does not do this, so the only way to debug a malfunctioning TPMS system is via sdr (or an expensive tool, or a trip to the tire store).
- kube-system 4y agoNot just "the" CAN bus, but the one you're sniffing. Many cars have multiple busses that carry different traffic.
- tedmid 4y agoYeah that’s really frustrating. Different manufacturers have different offerings here. My Toyota has nothing more than the lame “low pressure” warning, but my wife’s company Chevrolet actually shows numeric values for all 4 tires. Give us the data!!!
- jakear 4y agoA basic mechanical pressure sensor is the much cheaper and more reliable system.
- Johnny555 4y agoHow does a mechanical pressure sensor work? I've only seen electronic ones, how does the mechanical system warn the driver about low tire pressure while driving?
