Fighting the tire pressure monitoring system (TPMS)
This question is archived. No new answers are allowed, and only the question's owner may edit it.
Our Civic has two indicators that are part of the TPMS: a green(?) light with a flat-tire icon (meaning seems obvious), and an amber light with the letters "TPMS" that are supposed to indicate a more fundamental problem.
The amber TPMS light on our Civic has been on non-stop, but I haven't been satisfied with the answer from the dealer's service center: that the tires just needed more air. No, I topped them all off, but the light remains on. Besides, wouldn't the flat-tire light be the one to light up if tire pressure was the issue?
Anyway, my chief questions:
- How can I reset and retrain the TPMS myself?
- How can I pinpoint problems in the TPMS that would trigger the amber warning light?
- What TPMS problems can I fix myself?
