The Tiguan engine emissions lights often lit(III)

Due the auto diagnostic tool fault with the car or truck is half previous one particular will check out, and now the information stream is clearly the deviation is too massive, I feel around the Run in this kind of a time period of time after the fault code will nonetheless appear once more, it had been made a decision the issue very first the information inflow hand analysis, striving to locate the point of failure.

So as to confirm the accuracy on the data stream, specially repeatedly flame once again to start the engine, found every single startup information stream are to start with shut to -19%, and after that slowly climbed back to 18%, indicating that the issue does exist. Then triggered the failure what? Immediately after some discussion, the Injector seal terrible, leaks can cause the generation with the challenge. Evaluation of the idea is following the car ignition is turned off, given that the fuel injector is not sealed, the high-pressure fuel by means of the leakage in the injector in to the cylinder, the cylinder accumulation gasoline, to start the approach from the upcoming, the recently launched since the cylinder has been The fuel mixed normal gasoline also thick, the oxygen sensor might be detected as well thick signal back towards the J623, J623 will alter and lessen the quantity of fuel injection until revenue the adjustment value exceeds a certain worth Zaiwang Hui regulation. To confirm this, once the engine is running, disconnect the plug from the large stress fuel pump and fuel pump fuse till the engine shake and then immediately flip off gradually inside the gasoline line basically no gasoline. Plug and fuse plug it back in right after you turn off the key, and then promptly start off to observe the data stream, feeling right into a value lower than just some. Repeatedly attempted twice, chose to check out injector in exchange for that unique auto, the injector just altered totally new, but there isn't a promise that the new difficulty. But in exchange for your unique car or truck injector commences, the data movement has not improved, the injector can be excluded.

Under repair in difficulties, mixed with two Launch X431 GX3 fault codes and data flow, two oxygen sensors reflects a also lean, a reflection as well thick, the information stream to the adjustment worth too thick, and later on also thin, and significantly more than the normal selection . The ordinary understanding of both the engine handle unit J623 failure or J623 Bad Ground garbled seem Shiraai contradictory failure, but from now repair system to analyze line and J623 itself should really not have any difficulties. Then the question The place is it?

Is it Launch and X431 definitely the engine consumption method hasn't sealed the result of it? Through the difficulties code and data stream examination this is unlikely, but still the 1st test, start out the engine and enter the basic settings, input channel number 107, click Activate, the process commences to set, setting success display normal The program described to date will not seal the reason is usually excluded.
