Empowering Drivers P0068 Diagnostics for Enhanced Engine Performance

P0068 - There is a difference between the Manifold Absolute Pressure (MAP), Mass Air Flow (MAF), and Throttle position sensor (TPS) voltage values. The problem is very specific: On a second startup, when turned off for less than say an hour, car cannot hold an idle. Happens every trip to the grocery store. The MAF is the sensor for the throttle body. If I understand this code correctly, the MAF is showing an airflow that does not match an expected ... Could be caused by a vacuum leak or faulty MAP or Throttle Position Sensor. Done a work on it lately? Might have pulled of a vacuum hose? The P0068 code is triggered when a vehicle's Powertrain Control Module (PCM) detects an inaccurate signal coming from the air assisted fuel injector. A ... It could be the pressure drop is lower and you are seeing higher boost and hopefully at lower temps, which may need a tune revision. Do you have ... p0068 - Throttle Body Air Performance p0113 - Intake Air Temperature sensor circuit high voltage p0102 - MAF sensor circuit low frequency I have the trouble code p0068. Throttle position correlation. 03 ford explorer sport. 2003. I replaced the throttle. Code P0068 is basically when the MAF is reading more air than what the ECM has calculated for a specific RPM/Throttle Position/MAP. The code is telling you is that the throttle (position) is either open too much or not enough for the amount of air (pressure) that the MAP sensor is reading.
