Eclipse Emissions Testing Procedures And Ecu Replacement
Although an Eclipse ecu replacement is not an easy job, we included information on vehicle emissions testing for the ecu to help you better understand the testing procedure and what the computer test results mean. Vehicle emissions testing requires an expensive piece of equipment called an infrared exhaust analyzer. Some analyzers measure only two gases, hydrocarbons and carbon monoxide (HC and CO), while others measure three, HC, CO, and CO2 (carbon dioxide), or four, HC, CO, CO2, and O2 (oxygen) gases. Carbon dioxide and oxygen are not pollutants, but their level in the exhaust gases can be used for diagnostic purposes on catalytic converter equipped Eclipse vehicles. Exhaust analyzers cannot read oxides of nitrogen (NOx) levels. Most vehicle emissions checks begin with an underhood visual inspection to see whether any emission control devices have been disconnected or are missing. The inspector may also check the Eclipse gas tank filler neck to see if the unleaded fuel restricter has been punched out so regular leaded gasoline can be used.
The second part of the test involves inserting an exhaust analyzer probe into the vehicle's tailpipe and checking emissions at idle. Some tests also include running the Eclipse engine at higher speeds, but since pollution levels are greatest at idle, an idle check will usually catch any problems. Each state or metropolitan area is free to set their own ecu standards. The passfail point is usually set low enough so most Eclipse cars pass, but those emitting excessive pollution won't. The standards are determined by the model year vehicle, with standards for older vehicles being more lenient than those for newer ones. If an ecu fails an Eclipse emissions check engine light will activate, it means it is putting out too much HC or CO, or that the inspector found something missing or inoperative during his visual inspection.
In some states, there's a cost waiver that says if repairs bring a vehicle into compliance the law will exceed a certain dollar amount, then the Eclipse will be passed anyway. This is to avoid an undue financial hardship on those who can't afford to keep their vehicles ecu n good repair. Other states have no such waiver. And even in those states that do have a waiver, there is no waiver allowed for eclipse cars that have been deliberately tampered with. In other words, if the inspector finds that you've replaced the catalytic converter with a piece of exhaust pipe or disconnected any ecu control device, the vehicle must be restored to its original condition before it will be passed. Any missing or intentionally disconnected ecu emission control systems must be replaced regardless of cost. Since the specifics of vehicle emissions testing vary considerably from one area to another, we suggest you contact your state department of transportation or environmental control for details. Even if you live in an area where no periodic emissions checks are required, having a normal engine ecu your eclipse ecu checked at a local garage or dealership as part of a tune-up or diagnostic checkup can tell you a lot about your eclipse ecm health. Or, if your Eclipse fails a state required emissions check, knowing the causes of high HC and CO emissions can help you determine the repairs needed. High HC emissions often indicate an ignition problem such as a misfiring or fouled spark plug, a cracked distributor cap, or bad plug wire. Anything that interferes with good ignition will permit unburned fuel to pass through the eclipse ecu and into the exhaust.
Badly worn piston rings and valve guides that allow your engine ecu to burn oil will also cause high HC readings. Carburetor flooding. or an excessively rich fuel mixture likewise can contribute to high HC levels. Loss of compression due to a leaky valve or blown head gasket can pass unburned fuel into the exhaust, too. Carbon monoxide indicates incomplete combustion resulting from too much fuel and or not enough air. Things to check for here include a clogged air filter, sticking choke, misadjusted
carburetor, plugged or inoperative PCV system, or a problem in the air pump or air injection system. Overadvanced ignition ecu timing can also send eclipse co levels soaring.
