P0068 Decoded Empowering Drivers with Engine Insight

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 codes the mechanic found were 004759 - Pressure Drop between Turbo and Throttle Valve, 000104 - MAP/MAF - Throttle Position Correlation and 000257 - Mass ... Evo X Engine Management / Tuning Forums - P0068 maf/map tps correlation help - I keep getting this fault code on my 2011 gsr. Check the throttle position sensor and manifold absolute pressure sensor wiring harnesses first with an Ohm meter then boost leak test to locate any possible ... 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. my theory is the placement of the bov that is causing the code for most people. Its between both maps. when stock is use to releasing it farther ... 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. Most likely it's a loose vacuum hose... go look all around the intake and i bet you find it :) should be easier for you than the rest of us since you have a FMIC. The P0068 code signifies that there is a discrepancy between the readings of the MAP sensor, MAF sensor, and TPS, affecting engine ...
