Next check the coolant sensor, its electrical resistance drops as it gets warmer, so check at cold and after 1 minute running and there should be quite a difference. Clearing codes can change the way it's running but as soon as the computer runs through it's internal diagnostics it will turn the light back on if there is a problem. The engine was discontinued in 2003, replaced by the 2. In the L-body cars it was converted straight to Sequential Fuel injection. . Apr 17, 2013 Do you have any error codes to help in the diagnosis.
I run a dianostic computer on it said change exhaust sensor after cataletic converter an engine running lean! Although it displaces 134 cu. Since the computer thinks the car is running lean, it now is adding more fuel to the mixture to try and compensate for the lean condition and will always have a check engine light on. This engine was used in the and compact pickup trucks and their and counterparts until 1985, when it was replaced by the 2. The thermostat will removed by taking the two bolts off. This is why the engine idles quickly at start up. Oct 08, 2014 Your O2 sensor or oxygen sensor is located on your exhaust system.
Have a qualified technician run a fuel consumption test and go from there. An engine that is running lean shouldn't be using a lot of fuel. If there is no check engine light on then it probably is not a faulty O2 sensor. Failing that, it sounds as if your car is not entering 'closed loop' properly. This engine replaced the 1. Lean is when there isn't enough fuel going into the engine. If dirty take it out and give it a spray with residue free electrical cleaner do not use carb cleaner as it too harsh and leaves its own residue.
I changed it, after about 5 miles service engine soon light came back on,did the same now a code P1133,P0171,The 1133 heated oxygen sensor-Bank 1 sensor,0171 fuel trim bank one condition they say its the oxgen sensor before the catalitic converter! If the oxygen sensor is not working the computer continues as if the engine is in still 'open loop' mode. When lean lots of oxygen in the exhaust the output from the sensor is low voltage about 0. If the oxygen sensor is says, in error, that the exhaust is lean low or no voltage the computer will respond by increasing the fuel injected to compensate. This engine is equipped with , and is capable. The 2200 uses an iron block and aluminum 2-valve cylinder head. Then replace with a new thermostat.
One placed before your coverter to measure the efficiency of the combustion in your engine by measuring the amount of oxygen left in the exhaust stream. If not the sensor is bad and needs changing. When an engine is warming up, in 'open loop' mode, the engine's computer calls on the injectors to inject more fuel to keep the engine running, to warm up the engine quickly and to have the catalytic converter to start working early. A vacuum leak will give the O2 sensor a lean reading. Finally check the oxygen sensor.
Introduced with the models in 1982, the 1. The second O2 sensor is placed after the converter and its job is to measure the effiecency of the converter in filtering out harmful gases in the exhaust by compairing its reading to the sensor paced before the converter. Two other sensors that regulate fuel flow are the map sensor and throttle position sensor. First the fan will need to be taken off, then the cowl covering will need to be removed. Be sure to check for vacuum leaks at the manifold and lines as well as fittings. Temp sensor generally would cause a rich condition but I'd test that too.
When the engine is in 'closed loop' the engine is at normal running temperature and the computer no longer looks to the coolant sensor but to the oxygen sensor on the exhaust to establish the correct fuel air ratio. After these parts are removed, the thermostat is in plain view. If your O2 sensor has failed it will tell the car's computer that it is running too lean more air than fuel by default. In the related models it evolved through 2003 when it was known as the Vortec 2200. Changing a thermostat in a 1997 Dodge Ram 318 is very simple to do. Production ceased consistent with the replacement of the trucks with the sub-platform.
Mar 24, 2011 This sounds like an O2 sensor, there are 4 O2 sensors, 2 for each bank, 2 up stream by the exhaust manifold and 2 down stream by the catalytic converter. It is entirely different from the having been the last North American iteration of the. However the information you have given is limited, the explanation for the code seems to be missing some information. Then the thermostat will need to be pulled out using just the hands. Next check coolant levels, if coolant level low the coolant sensor may not be able to detect its temperature. Most fuel economy issues are due to the four areas above Apr 26, 2011 Something odd about what you posted.
After the hose is removed, loosen the nuts that are holding the thermostat in place. It produces 86 hp 64 kW. The coolant sensor informs the computer about engine temperature. Ex: right bank sensor 1 to lean. First the radiator hose will need to be removed from the thermostat.
