Wow, that's a pretty epic sensor coverage on that car. How does that work? I had to Google it, and came up with this example status: http://www.obd-codes.com/p

Wow, that's a pretty epic sensor coverage on that car.
How does that work? I had to Google it, and came up with this example status: http://www.obd-codes.com/p0452 http://www.obd-codes.com/p0452. It seems to be based off a fuel-tank pressure sensor. Neat.
- IgorPartola 12y agoIt was the OBD code + expertise from the AutoZone employee. He read the code that corresponded to a fuel leak detected somewhere and said the most likely cause is that the gas cap was not on tight enough. He said I can either try to re-tighten the cap, or just get a new one for $6 or so.
- a3n 12y agoThe only time my 1990 Honda Civic (original owner, looks like shit (both of us)) failed emissions test was a worn gas cap. When to $AUTO_PARTS_STORE, bought a cheap cap, passed test.
- auxym 12y agoI think gas-cap tightness sensors are pretty common, possibly mandatory? My 2004 hyundai accent, probably the cheapest car you could get in NA in that time, throws a CEL if you don't tighten the gas cap past 3 clicks or so, it's even documented in the user manual.
- refurb 12y agoIt's all related to emissions control. There are a number of sensors on modern cars that measure oxygen in exhaust gases, pressure in the fuel tank (to ensure vapors don't escape) and pressure in the EGR system (to lower NOx emissions). And that's just the basic setup. Higher-end cars monitor even more.
