P0068 The Gateway to Precise Engine Problem Identification

P0068- MAF sensor throttle psition correlation. Not sure exactly what that means . It may mean that the TPS voltage does not agree with the MAF. If the PCM detects that the difference between the actual air flow (MAF) and the speed density calculated air flow is greater than expected, DTC ... OBD-II Code P0068 means there is a correlation error between the Manifold Absolute Pressure (MAP) sensor, the Mass Airflow Sensor (MAF), ... I'm wondering if it doesn't have something to do with the expected voltages from the TPS at a certain voltage from the MAF. P0068 code no vacuum leaks tried maf and map and throttle pedal and throttle body,still doing the same, crank and dies unless you hold pedal to floor. Symptoms of problem are reduced gas mileage and surging just after transmission shifts while accelerating. 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. Faulty signal: -The throttle is sticking or is blocked (oil film, dust etc.) ... -Defective throttle unit. ... -Defective throttle unit. ... - ... 05 Touareg 3.2l v6, I have changed maf sensor, air filter and still keep getting P0068 code, any thoughts on where else to look or what to change next? You've got an air/vacuum leak somewhere and/or check your throttle body pigtail for a loose or broken connection. Keep in mind as well that the ...
