Question about 1999 Volvo C70

1 Answer

Check engine light.

I have had this repaired numerous time. Everytime the test is run the problem is with the gas cap. I have tried a new gas cap. Within 50 miles of having the light rest it comes on again. Sometimes it comes on before I get home form the mechanic. I have it reset everytime I have my oil changed. In Georgia with have emissions check every year. My car will not pass with this light on. Can you tell me how to reset it so that I don't have to continue paying $70 to have the test run?

Unfortunately the only way to reset that light is with a computer scanner. Autozone usually gives free diagnostics but I don't think they can turn off your light. Sounds like you need to have someone put a smoke machine on your vehicle to find the leak in your evap system. Hope this helps.

Gas cap indicaytor light came on. Changed cap and made sure it was tight but indicator light still comes on


The gas cap light is a generic light that indicates an emission problem. Usually a vacuum/pressure leak within the system. The gas cap is usually the first thing to check, however may not be the problem. There are numerous sensors and lines that control the vacuum/pressure/ of the fuel vapors and one of these is loose/disconnected/defective causing this light to come on. I would recommend inspecting hoses under the hood for any that may be loose/disconnected. You may also require a scan test to view sensor data to isolate the source of the light

Did the garage check the gas cap during the emission test? 90% of the time an evap leak turns out to be a bad gas cap. Or if someone had gas cap off while engine was running (pumping gas). Or if gas cap was not tightened all the way while driving. If this is the case, code saying evap leak, will clear after drive cycle self tests are done. Usually after 50 miles or more.(if the leak is solved)

Is the check engine light on ? Have you tried running it with the gas cap off ? The vent for the tank could be faulty. If you run it with the gas cap off, the check engine light may come on.

if the gas cap is installed properly(tightened),then you could have a code in the computer for the evap system that should be checked into.you will have to know what the code is to find what area of the system that needs to be checked out.

Got numerous "tighten gas cap" messages. finally


computer is seeing a large evap leak. most common cause is gas cap left loose this is why it is throwing up that message. since you have already done that we know there is a leak somewhere else. look underr vehicle and should see a black rectangular box close to gas tank this is the evap canister check the lines hooked to this and just do a visual inspection of hoses see if one has come off. may need to have it checked out we have a machine that hooks into system and pressurizes with "smoke" the smoke leaks out of the problem area and helps diagnose .

I don't know for sure, but I suspect the gas cap seal is leaking. Check the gas cap seal and mating surface for dirt. Buying a new cap might also be an option if you want to try that.
