What does erg mean.


I think you mean EGR which stands for exhaust gas recirculation. It is an emission device that recirculates unburned exhaust gasses back into the engine to be reburned thus lowering emissions and helping to cool cylinder temperatures

My hyundai sata fe 2005. was driving and sudenly lost all gears. no warning. foward and reverse. puleed to side of road. shut off checked for leaks none. turned back on drove fine for a few hundred feet....


Some vehicles are made with built in safety features to either not allow the vehicle to start or move if something serious is wrong. Don't know about the exhaust emission but could be in computer software to disable in case of excess emission. Could just be a bad O2 sensor. Need to fix the emission code problem, reboot the computer and try again.

How any oxygen sensors are on a 1999 grand cherokee laredo 4.0 & were is it/they located?


On Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines, check this diagrams...

The Oxygen Sensors (O2S) are attached to, and protrude into the vehicle exhaust system. Depending on the emission package, the vehicle may use a total of either 2 or 4 sensors.

Federal Emissions Package (4.0L and 4.7L engines):
Two sensors are used: upstream (referred to as 1/1) and downstream (referred to as 1/2). With this emission package, the upstream sensor (1/1) is located just before the main catalytic convertor. The downstream sensor (1/2) is located just after the main catalytic convertor.


California Emissions Package (4.0L engine):
On this emissions package, 4 sensors are used: 2 upstream (referred to as 1/1 and 2/1) and 2 downstream (referred to as 1/2 and 2/2). With this emission package, the rear/upper upstream sensor (2/1) is located in the exhaust downpipe just before the rear mini-catalytic convertor. The front/upper upstream sensor (1/1) is located in the exhaust downpipe just before the front mini-catalytic convertor. The rear/lower downstream sensor (2/2) is located in the exhaust downpipe just after the rear mini-catalytic convertor, and before the main catalytic convertor. The front/lower downstream sensor (1/2) is located in the exhaust downpipe just after the front mini-catalytic convertor, and before the main catalytic convertor.


California Emissions Package (4.7L engine):
On this emissions package, 4 sensors are used: 2 upstream (referred to as 1/1 and 2/1) and 2 downstream (referred to as 1/2 and 2/2). With this emission package, the right upstream sensor (2/1) is located in the right exhaust downpipe just before the mini-catalytic convertor. The left upstream sensor (1/1) is located in the left exhaust downpipe just before the mini-catalytic convertor. The right downstream sensor (2/2) is located in the right exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor. The left downstream sensor (1/2) is located in the left exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor.

What would cause 1996 Ford Explorer to overheat then idle high and low?


Only a few general concepts, keep in mind that the exhaust gas recirculation (EGR) valve is an integral part of a vehicles emissions control systems. It operates under the premise of lowering combustion chamber temperatures to reduce the amount of pollutants created by the combustion process. Being closely tied to the combustion process, this valve's operation has direct effect on the overall performance of the engine. Poor or faulty operation of the EGR valve can result in several notable symptoms and leads to increased pollutant emissions.

Poor Idle: An improperly closing EGR valve will act as a vacuum leak, disrupting the correct fuel and air mixture, causing a lean mixture condition. This results in misfiring cylinders and poor engine idle.

Overheating: The basic function of the EGR valve is to introduce exhaust gases into the combustion chamber at specific and controlled rates, lowering combustion temperatures, and lowering pollutant emissions. An EGR valve that does not open properly fails to introduce sufficient amounts of exhaust gases, causing combustion chamber temperatures to rise, leading to overheating of the engine.

Poor Fuel Economy: A sticking EGR valve will not open and close at the proper rate, leading to a reduction in the efficiency of the combustion process due to the lean fuel-air mixture it causes. This results in the engine having to work harder to perform the same amount of work, requiring more fuel to do it. On-board computer systems can also try to compensate for this lean condition by introducing additional fuel to the mixture, further increasing fuel consumption.

Increased Emissions: EGR valves are designed to lower the emission of pollutants from the combustion process. This is done by lowering the temperature of the combustion process through the introduction of exhaust gases into the fuel and air mixture. Lowered combustion temperatures result in more efficient burning of the fuel and air mixture, and less pollutants in the exhaust emissions. An improperly operating EGR valve will not correctly lower combustion temperatures, causing noxious emissions to increase, which can cause a vehicle to fail emissions inspection.

Test cylinders compression and check if some fault code is stored in the PCM 9computer).

The check engine light is on, the EGR valve has been replaced, code P0401 appears on diagnostic. The engine is 4 cyl DOHC 2 wd. slight exhaust odor at times in vehicle.


Are you reset the stored codes there? The EGR (Exhaust Gas Recirculation) valve controls an engine's emission of smog-causing nitrous oxides, or NOx. Its job is to route a portion of the exhaust gases back into the intake manifold. That lowers combustion temperature to below 2,500 degrees Fahrenheit - the temperature at which NOx gases form.

EGR flow is controlled by the engine's computer, which opens or closes the valve as needed. The EGR system is, for the most part, in the "out of sight, out of mind" category, and typical doesn't require regular maintenance. But if it gets clogged with carbon deposits, you'll see your "check engine" light come on, and a code (perhaps P0401 or P0402 or P0403) will show that there is insufficient flow. That typically results from a vehicle being driven persistently on short trips that don't allow the engine to fully warm up. Flow problems also can be caused by carbon buildup due to failure to change the oil frequently enough.

A clogged EGR valve not only results in higher emissions, it can affect fuel economy and cause rough idling - even serious engine damage. Valves can usually be cleaned, but replacement is often recommended.

About thie generic fault code, I suggtes check this description and tips for solution information: DTC-P0401-Tests (keep in midn that this code applied for alot brands, Hyundai included).

Keep us updated.

What is emission system


THE EMISSION SYSTEM IS DESIGNED TO TRAP AND STORE FUEL VAPORS THAT EVAPORATE FROM THE FUEL TANK.THROTTLE BODY AND INTAKE MANIFOLD DURING NON OPERATION OR IDLING STORE THEM IN THE CHARCOAL CANISTER AND THEN ROUTE THEM INTO THE COMBUSTION CHAMBER TO BE BURNED DURING ENGINE OPERATION.THE PCV VALVE ITS PART OF THE EMISSION SYSTEM.IT SCAVENGING CRANKCASE VAPORS IT DOES THIS BY CIRCULATING FRESH AIR FROM THE AIR CLEANER THROUGH THE CRANKCASE WHERE IT MIXES WITH BLOW BY GASES AND IS THEN REROUTED THROUGH A PCV VALVE TO THE INTAKE MANIFOLD.THE CATALYTIC CONVERTER IS PART OF THE EMISSION SYSTEM IT REDUCE POLLUTANTS FROM THE EXHAUST GAS STREAM IT LOWERS LEVELS OF OXIDES OF NITROGEN AS WELL AS HYDROCARBONS AND CARBON MONOXIDE.THE EGR VALVE PART OF EMISSION SYSTEM IT LOWER OXIDES OF NITROGEN EMISSION LEVELS CAUSED BY HIGH COMBUSTION TEMPERATURES.THE EGR VALVE RECIRCULATES A SMALL AMOUNT OF EXHAUST GASES INTO INTAKE MANIFOLD.SMOG PUMP IS ALSO EMISSION CONTROL COMPONENT IT INJECTING AIR INTO THE EXHAUST DOWNSTREAM FROM THE EXHAUST PORTS TO HELP COMPLETE THE COMBUSTION OF ANY UNBURNED GASES AFTER THEY LEAVE THE COMBUSTION CHAMBER.

Im trring to find the location of the o2 sensor it needs to be replaced but having trouble figuring out which one it is.


The upper O2 sensor is located on the exhaust manifold/s, and the rest is down the line. Some Vehicles have 2, 3, etc. The Upper O2 reads and helps control air/fuel mixture, the lowers usually monitor emissions, and Catalytic converter efficiency.

Sensor code P0404 -- emissions system


P0404 EGR valve problem
Change the Exhaust Gas Recirculation valve.
This valve puts some of the exhaust gas back into the engine to cool combustion (to reduce spark knock) and lowers HC (emissions).

Check exhaust emission control system and catalytic converter.
These items have been integrated into a highly effective system which controls exhaust emissions while maintaining good driveability and fuel economy.
