P0068-MAMFQLD PRESSURE/THROTTLE POSITION CORRELATION
' Image
Theory of Operation
This DTC sets when an unexpected high intake manifold air flow condition exists that
can lead to increased engine speed and puts the NGC into a High Air flow Protection
limiting mode. The High Air flow Protection feature includes RPM limits for when a
Throttle and or MAP sensor limp-in fault is present.
When Monitored
During all drive modes.
Set Condition
If vacuum drops below 1.5Hg with engine RPM greater than 2000 RPM and closed
throttle. One Trip Fault. Three good trips to turn off the MIL.
Possible Causes
-VACUUM LEAK
-RESISTANCE IN THE (FS56) 5-VOLT SUPPLY CIRCUIT
-(FS56) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (Kl) MAP SIGNAL CIRCUIT
-(Kl) MAP SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (FS55) 5-VOLT SUPPLY CIRCUIT
-(FS55) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K22) TP SENSOR NO. 1 SIGNAL CIRCUIT
-(K22) TP SENSOR NO. 1 SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K900) SENSOR GROUND CIRCUIT
-MAP SENSOR
-THROTTLE POSITION SENSOR
-PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Usual suspects include:
- Faulty Mass Air Flow (MAF) sensor
- Large vacuum leak
- Leaking air duct system
- Mass Air Flow (MAF) poor electrcial connection
- Manifold Absolute Pressure (MAP) poor electrcial connection
- Faulty Manifold Absolute Pressure (MAP) sensor
- TP sensor not seated properly
- Faulty Throttle Position (TP) sensor

P0068 on a 2006 Dodge Ram 1500 SLT. Rough "hunting" for idle. Momentary lag/loss of power from a stop. Random RPM changes while at a constant speed. Sometimes it feels like it drops out of gear...


P0068 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle Possible causes - Large vacuum leak
- Leaking air duct system
- Mass Air Flow (MAF) poor electrcial connection
- Manifold Absolute Pressure (MAP) poor electrcial connection
- Faulty Mass Air Flow (MAF) sensor
- Faulty Manifold Absolute Pressure (MAP) sensor
- TP sensor not seated properly.
- Faulty Throttle Position (TP) sensor.
- Dirty throttle body
When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings
P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.

Hello, I'm currently living on Guam and cannot find a mechanic who can correct my 2001 Dodge Durango (with error code P 0108) probelm. It will occassionally idle rough and stall. At times the "check...


P0108 = MAP sensor circuit high voltage

The MAP sensor communicates the barometric pressure inside the intake manifold to the ecm.
This code can indicate either a fault in the MAP (manifold absolute pressure) sensor, or a possible vacuum leak, either from a hose or the intake gasket.

It could be the connector on this sensor isn't making good contact. I would check the connector before you replace the sensor. It more than likely needs a new MAP sensor.

I have a POO68 code, what does this mean? My Durango surges when idle and now when I'm driving i have quick loses of power like not getting enough fuel for a split second.


P0068 MAP/MAF Throttle Position Correlation

That means that the Manifold Absolute Pressure data doesn't jibe with the Mass Air Flow Sensor data and the Throttle Position Sensor Data.

So, any one of these three items may be the cause of your problem.

LIkely, that the TPS is not giving accurate data, but must read codes from the computer to determine any further conclusions.

Wife's durango is idling rough and running rough


With both codes pointing at TP sensor, I'd certainly take the time to replace it, as well as make sure connections to it are clean, and good. Chances are, you won't be able to take part back anyway. As far as exhaust goes, if it's leaking in the right places in may cause improper readings at sensors downstream, but if not obvious leak, I wouldn't be concentrating in that area right now.

p0068 is Throttle Position sensor inconsistent with Mass Air Flow sensor.
