P0068 Mitsubishi Code - Manifold Absolute Pressure/Mass Air Flow Sensor - Throttle Position Correlation
Quick Answer
The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. Common causes include Faulty Mass Air Flow (MAF) sensor, Large vacuum leak, Leaking air duct system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

P0068 ....my Mitsubishi Chariot-Grandis 1998 has got the symptoms. Show me a diagram or illustration of the throttle position correlation. Thanks.
-
There is no diagram or illustration for a correlation problem. The code means that one of the sensor ( Manifold Absolute Pressure/Mass Air Flow Sensor or Throttle Position sensor ) it's not reading the correct values. Either one of the sensor may be faulty.

Ok thanks, but where are these sensors (including iac) located on my mitsubishi 1998 chariot grandis if I were to replace eiter one of them?
