Assume you mean the O2 sensor. In any case, you will have to reset the onboard computer to clear the code. If there is still a problem the code will re-appear after you run the engine again. The owners manual usually shows how to clear the code, if not go to your local library and look in some of the automotive reference manuals. I'm sure the error code did not say to replace the O2 sensor. The code gives a reference to what troubleshooting tree to use to help determine what the cause is. If it were the problem and you replaced it, it would have went through a self test and the light would have gone out on it's own, assuming there were no other problems that all of the monitors (self-tests) passed.
stop an engine
I changed erg valve o2 sensor and gas cap but lights back on what do I do
I will answer this question myself. First I changed out the o2 sensor because I needed one. (code) Next I changed out the MAP sensor. (code) End of problem.
Answer , location of temperature sensorI just changed the Temperature sensor on my Pontiac and it was located on the engine block right underneath the throttle control.
The check engine light will illuminate with a code(s) directing which O2 sensor is bad.
Need to know what code(s) were set and which O2 sensor you changed in order to help you.
check fuel pressure regulator
More than likely it needs to be reset.
The engine doesn't know when to fire the cylinders because it doesn't know where the cam shaft is. change the sensor.
If you are asking about the 2.0L engine....the ECM was changed to what is called a NGC and the crank and tone wheel(pickup for crank position sensor) was changed. Also, the blocks are not interchangeable due to the position of the crank sensor was changed. It may be possible to change the crank and and sensor then extend the harness to reach the front of the engine where it was move from the rear starting in 2003 but this would be alot of work. Everything else on the engine should changeover fine.
Check to see if the wiring is damaged.
The cam sensor is part of the distributor, the entire distributor needs changed. You can not get the cam sensor separately.
it has to be reset if you disconnect the battery for a few minutes should do it
no it does not due to the fact it does not have a camshaft. it does however have a crank sensor. the jeep 4.0L engine is a OHV engine not OHC. that means it is a pushrod engine instead of a camshaft driven engine
The crankshaft sensor, on an LDV Maxus can be changed by removing the rear engine cover. The sensor is attached to the crankshaft with 3 bolts. Remove the bolts and install the new sensor.
There is no knock sensor on a 94 4L jeep engine. In 1991 when they changed to the 4L HO motor, they removed the knock sensor from the system.
The crankshaft sensor in your 1990 former Roche is located on the front of the engine. The best way to test your crankshaft sensor is to hook the engine to a Dyno tester.
I don't think that there is a camshaft sensor on this engine. There is however, a crankshaft sensor that is located on the passenger side of the bellhousing where it meets the engine. It should be just to the passenger side of the distributor. There is s sensor in the distributor that does the same job as a cam sensor.
There are numerous problems with a strting and stopping engine. It could be the fuel pump, the crank sensor or the cam sensor. A fuel pressure test wil rule out the fuel pump, however the sensor are checked with a scanner, but usually have to be changed to find out which is at fault, don't rule out a plugged catalytic converter if there is an engine light on in the instrument cluster
Your transmission doesn't have an 02 sensor. The o2 sensor monitors engine exhaust to control engine performance. But, dirty transmission fluid is a problem and should be changed before it cause a major and very expensive transmission failure.
No, a defective oil pressure sensor will not harm the engine as long as the oil pressure is what it should be. However, how do you know what the pressure is if the sensor is bad. Replace the sensor so that you can receive a warning if the oil pressure drops below what is optimum.
Your O2 sensor is a "part that is designed to wear out". there is no standard on replacing them, but if your car is running fine, and your check engine light comes on, and stays on, it's probably an O2 sensor.
engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty.
on mine i just changed the o2 sensor located in the front by fan
