My check engine light keeps coming on in my 2004 Suzuki Verona. I have had it fixed once but it keeps coming back on. The funny thing is that it shuts off every time it rains and comes back on when the air gets dry. I’ve read that Suzuki’s have problems with check engine light… any suggestions on fixing it cheap or easy (i am trying to sell the car)
Sell it when it rains. Give us a clue. What behavior does the engine have when it misbehaves? What are the codes when the check engine comes on? If the light is on, an auto parts store will do the scan for you and put up the codes. Bring’em here for for cussin’ 'n discussion.
It isn’t a matter of “fixing the Check Engine Light” (CEL), but rather, a matter of fixing the underlying problem (or problems) causing the CEL to illuminate. Nobody can hazard a guess as to the exact problem or the cost to fix this unknown problem until you determine the trouble codes that have been stored by the car’s OBD II system.
Go to an auto parts store that does free OBD II scans, and then come back to this thread with the exact codes that are found. The codes will be in the format of “P1234”.
Auto Zone, Reilly Auto, and Advance Auto are some of the places where you might be able to go to for a free scan of your system’s trouble codes. Call a few of these places before you go, in order to determine who is still doing free scans in your area, and then report back to us on the findings.
OK. thanks for the info about the free codes at autozone. the car codes that came up were P0171 and P0174. I don’t know what these are and how they relate to the check engine light going off when it rains. Any help is greatly appreciated!
The codes P0171 and P0174 mean that both sides of the engine are running lean. “Lean” is when there is more air going into the engine (usually, the intake) than gets measured; OR, less fuel is going in than is metered (by the fuel injectors and the engine computer).
Check the engine over carefully for disconnected vacuum hoses, or ones split or cracked. You could spray the vacuum hoses with a soapy solution, while the engine runs. If the vacuum hose is leaking, the soapy solution will, visually, be sucked in. Moisture may be temporarily sealing cracked vacuum hose(s), when it rains.
