P0068 Explained Simplifying Engine Error Codes for Drivers

Error Code P0068 means the PCM has detected an excessive input voltage signal degree variation from the TIPS (Throttle Position Sensor) compared to the voltage ... The codes the mechanic found were 004759 - Pressure Drop between Turbo and Throttle Valve, 000104 - MAP/MAF - Throttle Position Correlation and 000257 - Mass ... manual says most likely a vacuum leak, but that doesnt really make sense since it was all of a sudden a problem and not a gradual problem. I ... The problem here could be the MAP sensor, but it could also be a defective throttle body, a leak in the intake system, a broken hose, or just lost calibration. That error code which I had on my Petrol A170 is caused by a slight leak between the throtal body and manifold that is picked up by the MAP ... P0068 - MAP/MAF - throttle position correlation P0299 - Turbocharger underboost condition U0422 - Invalid data received from body control module. It's showing codes P0068 & P0101 which is MAP/MAF throttle position sensor and mass or volume airflow A circuit range/performance. The car has as long as I have owned it (3 years) always had a surging idle when moving. Up and down, slowly. 7-800 to 2500 and back. The flow to low is computed based on the engine RPM, throttle position and manifold vacuum. Also it states "Overrun" which I assumes means that I removed my ... The three main things that can throw up code P0068 are , manifold pressure sensor, mass airflow sensor ,throttle position sensor .
