My check engine light is on, and the code is P0442, it's a Kia Spectra. What does the code mean?
Check all hoses on vehicle especially around canister and make sure u have a factory gas cap
The canister purge solenoid is part of the evaporative emissions system. When it is commanded "open" by the PCM (computer), it allows fuel vapors in the fuel system to enter the engine. This solenoid basically acts as a valve regulating fuel vapor flow to the air intake system. By burning these vapors in the combustion process, the evaporation system helps to lower overall vehicle emissions. The solenoid circuit refers to the wiring used to control the function of this solenoid, and usually runs between the solenoid and the vehicles PCM.
any defect in the above mentioned canister working will cause your problem to happen
Testimonial: "Thank you, exactly what I needed to know!!"
Code P0442 means Evaporative Emission Control System Leak Detected-(small leak). Most times that code is set if you removed the gas cap while the engine was running. If not, you could have a bad gas cap. It's minor in the grand scheme of things, but to be on the safe side, replace the gas cap, have the code cleared, and drive the car for a day or two. If the light stays off, problem solved.
The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light is turned on the computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible faults that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.
