Warning light that warns about problems encountered in the ECU of the car. It monitors the fuel system, the ignition system and the gases emission. The light may blink or remain on depending on the gravity of the issue.
The first problem that appeared was the the check engine light remains turned on. The error code suggests that there is a fuel leakage. The smoke machine was connected but nothing could be detected. I've changed the fuel lid but the check engine light is still on. The other problem that it has is power loss: when I am driving along an uphill road, the car won't go over 20 mph. If I remove the gear and put it neutral then the acceleration problem disappears. An error code has appeared suggesting that there is a valve failing but my mechanic said that was not the cause. It's been a year that I'm driving with these two inconvenients, can someone help me please?
Why don't you visit another mechanic and see what he suggests? It happened to me and, after visiting four different experts, the last found the cause of the problem and it was nothing too huge or expensive that needed to be repaired.
HI There, I have the same problem with my Nissan Pathfinder my mechanic said that the exhaust gas regulator value was very badly clogged up with carbon dioxide deposits. He found that problem the second time I complained that the engine light was on and on occasions power loss when accelerating. If I stopped and turned off the car then started it again the power came back.
