Unveiling the Complexities of P0068 The Comprehensive Diagnostic Guide

P0068 - There is a difference between the Manifold Absolute Pressure (MAP), Mass Air Flow (MAF), and Throttle position sensor (TPS) voltage values. check for vacuum leaks up and around the upper intake plenum...it is possible to have a bad lower intake gasket causing the problem too. The MIL was on for a while and then turned off. It seems like when the weather is warm the light comes on and in cooler weather the light stays off. Scanned the code and found the problem to be p0068 (maf/map throttle position correlation). I've seen this problem with the C300 and c350 but not a whole lot ... OBD-II Code P0068 means there is a correlation error between the Manifold Absolute Pressure (MAP) sensor, the Mass Airflow Sensor (MAF), ... 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? 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 ... Ok basically what that means is that the reading from the MAP sensor is not jiving with the reading from the Throttle Position Sensor. It could ... I'm having an issue with the car, it's throwing the code p0068, which looks like the MAF or MAP, further research leads to the problem may ...
