I have a 2003 Dodge Dakota 4.7L V-8 with the same problem (code 0442) which is a small Emissions leak, where a code 0441 is a larger vacuum leak. The problem is leaking vacuum hoses.

I replaced the gas cap, problem remained. After detaching the battery cable, thereby resetting the error, the dash light (code 0442) error would return in about 50 miles. The problem is the Natural Vacuum Leak Detection (NVLD) device. The NVLD is a device that detects any leaks in emissions system by monitoring vacuum pressure. As your engine warms up the difference in temperature creates a vacuum pressure change, if there is a leak, the vacuum pressure change is lost and the computer registers a fault.

My problem is with leaks in the vacuum hosing. For the 2003 Dakotahe NVLD is primarily made of two parts; an electical sending unit (behind the battery) and a vacuum chamber attached to the frame on the driver's side halfway between the engine and the gas tank. I replaced the rudder vacuum hose between the electical sending unit and the intake manifold ( less then $5.00 worth of hose) and another hose (special order) that attached to the vacuum canister (I think I paid $16.00).

This is a fix that can be accomplished by anyone that does the minimum level of wrenching. With mine truck I had to be careful of the 1/4" hard plastic vacuum lines that are used for most of the run between the sending unit and vacuum canister (the rudder hoses are used at both ends of the hard plastic lines.

Good luck.

Had similar problem, turns out I replaced with wrong style gas cap. If you have a 1/4 turn cap it must be replaced with another 1/4 turn cap and not one that screws on. Hope this helps.

1997 Buick, Gran Sport. Returning from a short trip I stopped to get gas the check engine light came on. I checked the gas cap but the light remained on for the rest of the trip. Any thoughts?

Could have been the gas cap. You'll need to get the engine computer scanned for trouble codes to find out. Once the problem is fixed, the codes must be erased to make the light go off.

P0172 fault code

It could be an emmissions problem. Sometimes even the gas cap being loose can cause a code. Make sure to tighten the cap when done should hear repetitive clicks when its tight. Other components related to code p0172 are o2 sensor(bank 1) and catalytic converters. Hope this helps!

The engine trouble light comes on I check it on my dianostic tool & I get a code 442. But I have no idea what that means, Can you help-?

Hello: 442 concern the evap system. It means you have a small leak. The most common item would be a gas cap that is not fully tight or the seal on the cap is dry and not sealing good. Try tightening the cap first, then get the code cleared and see if it comes back.

I have a Pontiac torrent 2006 and I receive the ccodes P0442 small leak from and P0771 lean bank1,previously went to dealer they kept saying gas cap. I need help I think its the converter or oxygen sensor...

A p0442 code is solved by replacing the gas cap in most cases, especially if it is the original gas cap. As for the p0771 lean code, there are many issues that can cause this code, O2 sensor, small exhaust leak, spark plug or fuel injector issue, spark issue...the list goes on. This code will need a good understanding with diagnostic procedure and testing and a scan tool would help. You may get lucky with replacing the spark plugs and checking for an exhaust leak and repair the exhaust. A scanner will allow you to see what the engine management components are doing while the engine is running. Keep in mind, it may take several good trips to turn the check engine light off after repairs are made and codes are erased.

Service engine soon light staying on

The "check engine" light is part of your car's so-called onboard diagnostics (OBD) system.

If the check-engine light comes on, here are some tips on what you should do:
  • Look for a serious problem that requires immediate attention. Check your dashboard gauges and lights for indications of low oil pressure or overheating. These conditions mean you should pull over and shut off the engine as soon as you can find a safe place to do so. On some cars, a yellow "check engine" means investigate the problem, while a red "check engine" means stop right now.
  • Try tightening your gas cap. This often solves the problem. Keep in mind that it may take several trips before the light resets. Some vehicles have a separate indicator that warns of a loose gas cap before the condition sets off the "check engine" light.
  • Reduce speed and load. If the "check engine" light is blinking or you notice any serious performance problems, such as a loss of power, reduce your speed and try to reduce the load on the engine. For example, it would be a good idea to stop towing a trailer. Have the car checked as soon as possible to prevent expensive damage.
  • Contact OnStar, if available. If you have a 1997 or later General Motors vehicle equipped with OnStar and an active OnStar subscription, contact an advisor who can read the trouble code remotely and advise you about what to do.
  • Have the code read and the problem fixed. If you want to diagnose the malfunction yourself, you can buy a scan tool at most auto parts stores. Prices range from about $40 to several hundred, depending on the model and the features. The tools come with instructions on how to hook them up and decipher the codes. But unless you have a good knowledge of automotive diagnostics, you're probably better off taking the vehicle to a professional. Some automotive parts stores will read and interpret the code for you without charge. Unless there is an easy fix, they may simply refer you to a mechanic.
  • Don't go for a state emissions test. In a late-model car, an illuminated "check engine" light probably is a sure sign your car will fail the test. In some states, it's an automatic failure, even if the problem was nothing more than a loose gas cap. By the way, don't bother trying to fool the inspection station by disconnecting the battery or using any other method to erase the trouble code and turn off the "check engine" light. Your vehicle's computer will let the inspection station know that its codes have been erased, and you'll just have to go back again.

Hope helps.

Take it to autozone and get a free dianostic check with a scan tool. The code will point you in the right direction to diagnos the problem.
