Why wont the check engine light go away?
These may be few possible reasons why the check engine light won't go away after replacing the O2 sensor in your 2000 Mitsubishi Eclipse V6
·The wrong O2 sensor was replaced or the O2 sensor is properly connected to the wiring harness(any signs of damage or corrosion).
·Sometimes, issues with the engine, such as misfires, vacuum leaks, or problems with the fuel system, can trigger the O2 sensor to report a problem. Ensure your engine is running smoothly and there are no other issues that could affect air/fuel ratios.
·The new O2 sensor is defective. If the O2 sensor is working properly, then the check engine light could be due to another problem with the exhaust system, such as a leak or a problem with the catalytic converter.
·Problem with the wiring to the O2 sensor. If the wiring to the O2 sensor is damaged or corroded, it can cause the sensor to malfunction and trigger the check engine light. To diagnose the exact cause of the problem, you will need to have the car scanned by a qualified mechanic. The mechanic will be able to read the trouble codes from the computer and use that information to pinpoint the problem.

There are a few possible reasons why your 2014 Fuso 515 manual transmission might not shift from neutral into gears when the engine is running but will shift when the engine is not running.
The clutch is not disengaging properly: The clutch is responsible for engaging and disengaging the transmission from the engine. If the clutch is not disengaging properly, it can cause the transmission to not shift gears properly.
The synchronizers are worn or damaged: The synchronizers are located in the transmission and help to match the speed of the engine and the transmission when shifting gears. If the synchronizers are worn or damaged, it can cause the transmission to not shift gears properly.
The transmission fluid is low or dirty: The transmission fluid lubricates and cools the transmission. If the transmission fluid is low or dirty, it can cause the transmission to not shift gears properly.
The transmission is faulty: If the transmission is faulty, it can cause the transmission to not shift gears properly.
If you are experiencing this problem, it is important to have your vehicle diagnosed by a qualified mechanic to determine the root cause of the problem. Once the cause of the problem has been identified, the mechanic can recommend the necessary repairs.
Here are some tips to help prevent this problem from happening in the future:
Use the clutch properly: When shifting gears, use the clutch to disengage the transmission from the engine.
Have your transmission serviced regularly: The transmission fluid should be changed according to the manufacturer's recommendations.
Avoid shifting gears when the engine is under load: When the engine is under load, it can put stress on the transmission and cause problems.
